General information

Congratulations with the purchase of Batterytester. The Batterytester is specifically developed for testing

e-Bike batteries and other rechargeable batteries between 6V –48V. Already in the development stage of

Batterytester we stressed the fact that the testing of an e-bike battery should be as user-friendly as

possible. A thorough knowledge of e-bike battery technology is not necessary however we advise

everyone who is involved with e-bike batteries to invest into a course or study about battery technology.

This manual gives all information needed to test e-bike batteries in a reliable manner. We advise

everyone for a proper use of Batterytester to read this manual completely. In case of not following the

stipulations in this manual we exclude all forms of liability.

Testing of e-bike batteries has many advantages for you. The only way to measure the capacity of an e-

bike battery is by discharging this under resistance. E-bike manufacturers deliver software by which the

BMS can be read-out. Please be aware that this does not give any true value about the e-bike battery’s

capacity. On our website: www.batterytester.nl you will find more information and you can follow the

developments of Batterytester. You can also follow us on LinkedIn

(https://www.linkedin.com/company/batterytester-e-powered-by-flamec-bv/)

and Facebook (https://www.facebook.com/accutester/?ref=aymt_homepage_panel).

Which batteries I can test with Batterytester?

Batterytester can test all rechargeable batteries in a range of 6 –48V (min3V –max 60V). The following

types of batteries can be tested with Batterytester:

•Lead

•NiCd

•NIMH

•Lithium Ion

When your battery is not mentioned in the above list or you doubt about the type of battery you want to

test please send an email to: [email protected]. Please indicate the type of battery, description and

some pictures. After we received your email we will check if it is possible to test your batteries with

Batterytester.

All above mentioned batteries can be tested with Batterytester. Besides the types of batteries there are

also different brands of batteries. Depending on the type of battery a certain cable or adapter might be

needed in order to be able to test the battery concerned.

User instructions:

Batterytester can be used as stand-alone unit and also be connected to a PC / Laptop. The differences will

be explained below.

For both versions of testing e-bike batteries applies the following:

The basic rule for a reliable battery capacity test is to discharge the battery with approximately the same

load as for which it is designed. We recommend to always take the half of the Ah listed on the battery. If

a battery has a nominal value of 10Ah, the discharge current should be set at 5A. This automatically

means that the battery test will take approx. 2 hours (10Ah/5A=2).

When you choose a higher discharge current as the nominal Ah stated on the battery this means:

•Risk of damage of the battery because of risk of battery damage;

•A prematurely abandoned test due to the thermal safety (safety provision in the battery because

of the battery management system (BMS);

•Unreliable test results because of thermal losses.

Batterytester has developed an automatic programme in which e-bike batteries will be discharged with a

set 5A load. However this load is changed every minute by half. The only way to test battery capacity is

by having a changing load. Even if you do not make use of the automatic programme the load is halved

every minute. E.g. if you decided to discharge the battery with 7A, Batterytester will every minute

decrease to 3.5A shortly and after go up to 7A again.

Using Batterytester without connection to a PC / Laptop)

When using Batterytester without a connection to a PC / Laptop you can print the test result from the

integrated thermal printer on a cashier paper. Please be aware that the readability will deteriorate over

time. Using Batterytester without a PC / Laptop is often done for internal purposes. The test result is

stated in Wh (Watt per hour).

Steps for a battery test without connection to a PC / Laptop:

1. Please take care that Batterytester is switched off;

2. Please take care that the ventilation output is not covered. Place Batterytester in a spacious area

and only use Batterytester indoors;

3. Connect the 12 Vdc Power Supply. First in the Batterytester;

4. Connect the fully charged battery. WARNING, check the polarity;

5. Turn Batterytester ON;

6. Press shortly the ‘Select’ button for the automatic testing procedure (the battery will be

discharged with 5A and the current where Batterytester will stop (Ustop) the test is set as follows:

Uopen (opening current) * 0.72 = Ustop. The Ustop is set in order to prevent deep charging the

battery;

7. Hold the ‘Select’ button for a longer time if you want to manually change these settings (select

discharge current (I) by turning the ‘Select’ button and press the ‘Select’ button by fixing the

discharge current. This also applies fort he Ustop. When changing the Ustop one has to know

what one is doing. In case the battery is discharged with a too heavy load the battery will be

heated and the test will be stopped prematurely;

www.batterytester.nl

Page 7/19

8. Batterytester is now discharging the battery. The discharge session will take several time

depending on the battery capacity and the set discharge current.

9. If needed, press the ‘Select’ button for a pause, change the discharge current or stop the test if

needed (turn, press to confirm);

10. When the test has finished “test ready”, one can print the result by pressing once again the

‘Select’ button. By pressing multiple times this button multiple test results will be printed;

11. Compare the test result with the battery specifications. On the cashier paper at the bottom line is

stated the capacity in Wh. If the battery stated it has a nominal capacity of 540 Wh and from the

test it appears is still has 500 Wh capacity left the percentage is (500/540)*100=92.6%;

12. After the test you need to charge the battery again in order to prevent capacity loss and deep

charge.

Using Batterytester with connection to a laptop / PC)

By connection Batterytester with a USB cable to a PC / Laptop the user has the following advantages:

1. In the Batterytester Software Programme the user can fill out the nominal data (Voltage,

Amperage, Watt per hour). At the end of the test the nominal data is being compared to the

tested data and this automatically results in a capacity percentage present;

2. The user can also fill out a description of the test. E.g. the customer name, addressed can be filled

out;

3. At the end of the test a PDF test report can be printed. This test report also demonstrates

different graphs;

4. Batterytester saves the test report as well as a ‘.csv’ file. In this file you can find all measured data

per measurement item in a Excel File. This gives you the opportunity to create your own reports.

Testing an e-bike battery with Batterytester when connected to a PC /Laptop is often done if the test

result is shown to a third party (customer / supplier).

Steps for testing an e-bike battery when Batterytester is connected to a PC / Laptop:

1. Please take care that Batterytester is switched off;

2. Please take care that the ventilation output is not covered. Place Batterytester in a spacious area

and only use Batterytester indoors;

3. Connect the 12 Vdc Power Supply. First in the Batterytester;

4. Connect the fully charged battery. WARNING, check the polarity;

5. Connect the USB cable to the Batterytester and the PC / Laptop. Start the Batterytester Software

Programme on your PC / Laptop. Select the ‘COM’ port, fill out a file name, fill out the nominal

data of your battery (V, Ah, Wh), press ‘connect’, fill out the data of your customer, press

‘connect’;

6. Turn Batterytester ON;

7. Press shortly the ‘Select’ button for the automatic testing procedure (the battery will be

discharged with 5A and the current where Batterytester will stop (Ustop) the test is set as follows:

Uopen (opening current) * 0.72 = Ustop. The Ustop is set in order to prevent deep charging the

battery;

8. Hold the ‘Select’ button for a longer time if you want to manually change these settings (select

discharge current (I) by turning the ‘Select’ button and press the ‘Select’ button by fixing the

discharge current. This also applies for the Ustop. When changing the Ustop one has to know

www.batterytester.nl

Page 8/19

what one is doing. In case the battery is discharged with a too heavy load the battery will be

heated and the test will be stopped prematurely;

9. Batterytester is now discharging the battery. The discharge session will take several time

depending on the battery capacity and the set discharge current.

10. If needed, press the ‘Select’ button for a pause, change the discharge current or stop the test if

needed (turn, press to confirm);

11. After testing “test ready” you can print the test result both from the Batterytester itself (Select

button) and also via the Batterytester Software Programme. If you select a PDF printer you can

save the test report on your PC / Laptop;

12. After the test you need to charge the battery again in order to prevent capacity loss and deep

charge.

How do I judge the test result?

To judge the battery test result depends for which the tested battery is used. In general the common

value is that batteries with a capacity < 70% are economically depreciated. As there is many difference

between the different types of batteries / battery brands you need to consult your battery supplier about

the expectations of the batteries’ capacity over the years. In case you use Batterytester for a customer

who wants to exchange his or her e-bike for a new one you can offer a well-funded price for the

exchange bike.

Besides the fact that Batterytester is a service tool you can also use Batterytester as a sales tool. Based

on the battery test report you can possibly convince your customer to purchase a new e-bike battery. Of

course you can also ask for a testing fee for a battery test.

Quick test, capacity test in which the driving behaviour is simulated

In order to determine the battery capacity, the battery needs to be discharged with a varying load. This is

the only right way to determine the available capacity. In order to determine this a full capacity test

needs to be executed. This is not possible with a so-called ‘quick test’. However it is possible to

determine via a ‘quick test’ if the battery is in a bad condition. This is the case when the resistance (Ohm)

shows a too high figure. Batterytester has opted not to implement a separate programme for a ‘quick

test’. From the standard test programme the internal resistance is indicated on both the display and

when connected to a PC /Laptop in the Software Programme. This requires some knowledge about

battery technology. We recommend however to execute a full battery capacity test.

Software & Firmware

With a Batterytester, the Batterytester Software Programme is included. This Software Programme also

takes care of automatic firmware updates. To be clear: The firmware is the ‘software’ present in the

Batterytester itself. When we speak about the Batterytester Software Programme we mean the

programme you install on your PC / Laptop (Windows only).

When we have essential improvements in the operation of our Batterytester these will be implemented

in firmware updates. An example of a firmware update is e.g. if the test cable between Batterytester and

the battery gets disconnected (for whatever reason) in the past one had to restart the battery test all

over again. With the firmware update one is able to turn the ‘Select’ button and select the ‘continue test’

option.

refuse to accept the products neither/nor to refuse settlement of the amounts owed by them to Batterytester on account of the agreement.

6. If it was not possible to deliver the products due to a circumstance which can be attributed to the counterparty, Batterytester will store the products at the

risk and expense of the counterparty, without prejudice to the obligation of the counterparty to settle the amounts owed by them to Batterytester on

account of the agreement. The additional costs which are to be incurred in connection with the non-reception by the counterparty as intended here, such

as additional delivery costs and storage costs, will be borne by the counterparty. In case storage costs are impossible to determine sufficiently, they will be

fixed by Batterytester in a reasonable manner.

7. In case it was impossible to deliver the products due to a circumstance which can be attributed to the counterparty, the counterparty will accept the

products in second instance still, within a reasonable term to be set by Batterytester, failing which Batterytester will be authorised to rescind the agreement

while the counterparty will be obligated to settle the amounts owed by them to Batterytester on account of the agreement, also including the additional

costs as intended in the preceding section.

www.batterytester.nl

Page 17/19

ARTICLE 5. | DELIVERY TERMS

1. Batterytester exerts itself to comply with the delivery terms it has committed itself to vis-a-vis the counterparty, but these terms can never be considered

fatal time limits. The default of Batterytester will no sooner become effective than after the counterparty has formally notified Batterytester of their default,

which notification mentions a reasonable term for compliance, and Batterytester still remains in default with regard to compliance after expiry of the latter

term.

2. If Batterytester depends on information which is to be provided by counterparty for the implementation of the agreement, delivery terms no sooner

commence than after Batterytester has received this information.

3. In the event of default of Batterytester as intended in section 1, the counterparty has the right to rescind the agreement, without the counterparty being

entitled to claim further indemnification than restitution or remission of the established price in proportion to the non-delivered part of the agreement as

a result of the default.

ARTICLE 6. | SPECIAL OBLIGATIONS FOR RESELLERS

1. Batterytester guarantees the counterparty acting as a reseller the constant, established quality of the delivered products. The counterparty acting as a

reseller of the products, bears its own responsibility for fulfilling its legal obligations towards its final customers. Without prejudice to the preceding in this

section, resale to purchasers of the counterparty takes place at the own risk and expense of the counterparty.

2. Any collaboration between the reseller and Batterytester never is exclusive, unless it is expressly established otherwise; Batterytester has the right to

appoint multiple resellers, without any geographical restrictions.

3. Batterytester grants the reseller the right to make use of the brand name of Batterytester (“Batterytester”) and of their logos, though exclusively to the

extent and for the duration in must be considered reasonably admissible within the framework of the resale activities of the counterparty, and in conformity

with all possible instructions of Batterytester with regard to their use. For the use of the brand name of Batterytester and their logos in any other sense

than as is intended in the preceding sentence, prior written consent of Batterytester is required.

4. The reseller is obligated to use the brand name and markings applied by Batterytester in connection with the resale of the products. It is not permitted to

the counterparty to remove or alter brand names and/or markings of the products, nor to apply their own markings to the products.

ARTICLE 7. | WARRANTY, INVESTIGATION, AND COMPLAINTS

1. Batterytester will deliver products which comply with the normal trade quality as applicable within the EU. In the event of usage or resale of the products

outside the EU, the counterparty itself must verify whether the items are suitable for usage over there, and must ensure that the conditions as are imposed

in the relevant country are complied with. For the rest, Batterytester only supplies the products with a warranty to the extent this is expressly agreed on by

parties, or to the extent this was specified emphatically by Batterytester upon adoption of the agreement.

2. Without prejudice to their possible claims to warranty, the counterparty must investigate on the moment of delivery whether the nature and quantity of

the products correspond with the agreement. In case the nature and/or the quantity of the products in the opinion of the counterparty do/does not

correspond with the agreement, they must (let) make note of it on the packing slip. In case the products are picked up by or on behalf of the counterparty,

the principle applies that by reception of the products it is tacitly declared that the nature and quantity of the products correspond with the agreement,

unless, prior to reception, a reservation is made with regard to it in writing.

3. In the event of reasonably invisible defects, or of such which were otherwise impossible to be aware of at the moment of delivery, of products, the

counterparty must communicate such to Batterytester within seven days after discovering the defect, or at least after it should reasonably have been able

to discover it, in writing.

4. If the counterparty does not file the complaint on time, such complaint entails no obligation whatsoever for Batterytester.

ARTICLE 9. | SUSPENSION AND RESCISSION

1. In case the circumstances of the case reasonably justify such, Batterytester is authorised to suspend the implementation of the agreement or to completely

or partially rescind the agreement with immediate effect, if:

a) the counterparty does not, not timely, or not fully comply with its (payment) obligations; or,

b) after adoption of the agreement, circumstances come to the cognisance of Batterytester which are grounds to fear that the counterparty will not fulfill

its obligations, the counterparty has been requested to pledge security for compliance and this security has failed to materialize within a reasonable

term stipulated for it by Batterytester.

2. If fulfillment of the obligations of the counterparty with regard to which it falls short as intended in section 1 under a, is not permanently impossible, the

competence to rescind only becomes effective after the counterparty’s default has been notified in writing, in which notification a reasonable term is stated

within which the counterparty is still able to fulfill its obligations and fulfillment has still failed to be provided after expiry of the latter term.

3. The counterparty is obligated to compensate the damage which Batterytester suffers as a result of the suspension or rescission of the agreement.

7. In the absence of timely payment, the default of the counterparty becomes legally effective. From the day that the default of the party enters into effect,

agreement, are borne by the counterparty.

ARTICLE 11. | LIABILITY AND SAFEGUARDS

1. To use battery testing devices delivered by Batterytester, knowledge of battery technique is required. Batterytester advises end-users to acquire knowledge

of battery technique through education, a course, or training which are certified to that effect. The reseller is responsible for providing this information to

its purchasers. Batterytester does not accept any liability for damage (both caused to batteries for which the delivered product is used, and otherwise),

caused by the incorrect or inexpert handling of the product, by the incorrect or inexpert application of the product, and by use of the product which violates

or is non-compliant with the instructions manual included or other instructions of Batterytester. Furthermore, Batterytester does not accept any liability

for damage caused as a result of the lack of a product, which lack has occurred as a consequence of an external cause or of another circumstance which

cannot be attributed to Batterytester, including, though not limited to, defects as a result of damaging, natural wear, the inexpert and regular maintenance

and application of changes to the products (by third parties), which also includes repairs which are carried out without the previous written consent of

Batterytester.

2. The counterparty sustains the damage caused by inaccuracies or incompleteness of the information provided by the counterparty, which emphatically

includes the information regarding the delivery address. In addition, the counterparty sustains the damage caused by shortcomings in the fulfillment of the

obligations of the counterparty pursuant to the Law or the agreement.

3. Batterytester is never liable for consequential damage, which also includes loss of profit, losses incurred, and damage resulting from operational stagnation.

4. In the event Batterytester were to be liable for any damage, Batterytester will at all times have the right to repair this damage. The counterparty must

enable Batterytester, failing which all liability of Batterytester concerning will lapse.

5. Brring intent and gross negligence on their part, the liability of Batterytester is always limited to a maximum of the invoice value of the agreement, or at

least of that part of the agreement which the liability of Batterytester regards. In case the damage for which Batterytester may be liable, notwithstanding

the provisions in the rest of these general conditions, were to be excessive, such liability will be limited to no more than the amount which in the relevant

case is effectively disbursed on account of the business liability insurance taken out by Batterytester, increased by any possible deductible of Batterytester

which is applied pursuant to that insurance.

6. In derogation to the statutory limitation term, the limitation term of all legal claims on Batterytester amounts to one year.

7. The counterparty and especially the reseller of the products, safeguards Batterytester against any potential claims by third parties that incur damage in

connection with the implementation of the agreement, and of which the cause cannot be attributed to Batterytester. If Batterytester were to be addressed

by third parties on such account, the counterparty will be obligated to support Batterytester both extrajudicially and judicially, and to immediately carry

out all such things which may reasonably be expected of them in such case. Were the counterparty to fail in the taking of adequate measures, Batterytester

will have the right, without any default notice, to take such measures itself. All costs and damage on the part of Batterytester and of third parties that have

resulted, will be integrally at the risk and expense of the counterparty.
