4-STAGE AUTOMATIC CHARGING
The AC008 & AC015 are fully automatic battery chargers with 4 charge stages.
Automatic charging protects your battery from being overcharged so you can leave the
charger connected to the battery indefinitely.
4-stage charging is a sophisticated charging technique that gives your battery longer life and
better performance compared to using traditional chargers.
Projecta’s Charge N’ Maintain Battery Chargers are suitable for most 12V automotive,
marine and Lithium batteries.
The 4 charge stages are:
Battery Health Check, Bulk, Absorption and Float.
BATTERY HEALTH CHECK,
Checks to make sure the battery can accept charge.
BULK (CONSTANT CURRENT)
The Bulk stage reduces charging time by charging the battery at the maximum rate (constant
current) to a set voltage, at which point the battery is approximately 80% charged.
ABSORPTION (CONSTANT VOLTAGE)
The absorption stage charges the battery to 100% by adjusting the charge rate allowing
the battery to absorb more power.
FLOAT
The Float stage maintains the battery at 100% charge without overcharging or damaging
the battery. This means the charger can be left connected to the battery indefinitely.
FEATURES
SWITCHMODE TECHNOLOGY
Using the latest technology in battery chargers, switchmode chargers convert 240V AC
power to 12V DC power using electronic components unlike traditional battery chargers that
rely on heavy transformers. This allows the charger to be lightweight and compact without
sacrificing on performance.
SPARK-FREE AND POLARITY PROTECTED
All Projecta Charge ‘N’ Maintain battery chargers are spark-free and are protected against
accidental reverse connection making them safer to use around batteries.
WEATHER PROOF IP65
The chargers are IP65 rated which means they can be used outside without getting
damaged. Although the charger is a 240VAC device care should be taken that the plug
is not submersed in water.
LED CHARGE INDICATOR
The LED Charge Indicator is bi-colour and is green when charging and fully charged and
yellow if there is a fault.

CHARGING INSTRUCTIONS
STEP 1 – CHECK THE ELECTROLYTE LEVEL
Prior to charging the battery, remove the vent caps and check the electrolyte level (not
required on sealed & maintenance free batteries). The electrolyte should be 6mm (1/4”)
above the battery’s plates. If low, top up with distilled water to the correct level and refit
the vent caps.
STEP 2 – CONNECT TO BATTERY
There are three options for connecting to a battery.
Step 2A – Connecting to a battery that is out of the vehicle
Step 2B – Connecting to a battery fitted to a vehicle
Step 2C – Permanent hard wiring connection to a battery
STEP 2A – BATTERY OUT OF VEHICLE
Connect the RED lead (battery clip) from the charger to the Positive (+) battery post.
Connect the BLACK lead (battery clip) from the charger to the Negative (-) battery post.
STEP 2B – BATTERY IN VEHICLE
Determine if the vehicle is Positively (+) or Negatively (-) earthed. Negatively earthed
vehicles have a cable (usually black) from the Negative battery terminal to the
vehicle’s chassis.
Negatively earthed (most vehicles)
Connect the RED lead (battery clip) from the charger to the Positive (+) battery terminal.
Connect the BLACK lead (battery clip) from the charger to the vehicle’s chassis away from
the fuel line or moving parts.
Connection out of vehicle
Connection in vehicle
(negatively earthed)

Positively earthed
Connect the BLACK lead (battery clip) from the charger to the Negative (-) battery terminal.
Connect the RED lead (battery clip) from the charger to the vehicle’s chassis away from the
fuel line or moving parts.
STEP 2C – PERMANENT HARD WIRING
It is possible to hard wire the DC charging leads to the battery for permanent installations.
Use the supplied fused wiring harness.
AC008 use 1A fuse
AC015 uses 3A fuse
Connection:
1. Connect the RED lead (with inline fuse and ring terminal) to the Positive (+) battery post,
remove the supplied fuse.
2. Connect the BLACK lead (with ring terminal) to the Negative (-) battery post.
3. Fit the correctly rated fuse.
If the charger is used in a Permanent/Hard Wired application and the vehicle will not be used
for some time, it is best to leave the charger connected to mains power (turned ‘On’) so that
it can maintain the battery fully charged.
Ensure any modification to the 240V mains lead is carried out by a qualified person and that
connection to supply mains is in accordance with National wiring rules.
STEP 3 – CONNECT TO 240V MAINS POWER
Connect the battery charger to the 240V mains powered socket and turn on the mains power.
STEP 4 – CHARGING
The charging L.E.D should be on whilst charging and the full L.E.D will turn on when
fully charged.

STEP 5 – DISCONNECTION
Ensure the 240V mains switch is turned off and the charger is disconnected from the 240V
mains power.
Battery out of vehicle
Remove the BLACK lead (battery clip) from the battery.
Remove the RED lead (battery clip) from battery.
Battery in vehicle
Remove the chassis connection.
Remove the battery terminal connection.

PRODUCT OVERVIEW
FREQUENTLY ASKED QUESTIONS
Q. How do I know if the battery is charged?
A. The charger will indicate full on the display. Alternatively use a Battery Hydrometer
(Projecta Part No. BH100). A reading of 1.250 or more in each cell indicates a fully
charged battery.
Q. I have connected the charger properly but the Charger won’t start charging?
A. In some cases batteries can be flattened to the point where they have very little or no
voltage. This can occur if a small amount of power is used for a long time, for example
a map reading light is left on for a week or more. Projecta Charge N’ Maintain battery
chargers are designed to charge from 2.0 Volts.
If the voltage is lower than the voltages stated above use a pair of booster cables to
connect between two batteries to provide more than 2.0 Volts to the battery being
charged. The charger can then start to charge the battery and the booster cables can
be removed.
Q. Can I use the charger as a power supply?
A. Projecta chargers are designed to only supply power to the battery clips when they
are connected correctly to a battery. This is to prevent sparks during connection to the
battery or if connected incorrectly by mistake. This safety feature prevents the charger
from being used as a ‘Power Supply’
Q. How can I tell what stage the battery charger is in?
A. The LED indicators will show Green flashing when charging and Green solid on when
fully charged.
