USER MANUAL
Version 1.0
created : 08/06/2019
Thank you for your purchase of an AUD OROOT eSMART Li-
48neo or Li-96neo battery. We strongly recommend that you
read this instruction manual before using your eSMART Li-neo
battery! Please keep this manual for future reference.
Safety instructions :
For safety reasons, users are responsible for familiarizing themselves with the contents of this manual and
all warnings before use.
The cells inside a li-ion battery pack contains flammable items such as organic solvents. f the battery is
mishandled, it may cause fire, smoke or an explosion and the battery’s functionality will be seriously
damaged.
Observe the following precautions:
•
Risks of explosion
◦
Do not subject the battery pack to strong impacts.
◦
Do not crush or puncture the battery pack.
◦
Do not dispose of the battery pack in a fire.
•
Risks of fire
◦
Do not expose the battery pack to temperatures in excess of 60°C.
◦
Do not place the battery pack near a heat source, such as a fireplace.
◦
Do not expose the battery pack to direct sunlight.
•
Risks of damage to the battery module
◦
Do not disassemble the battery pack.
◦
Do not allow the battery pack to get in contact with liquids.
◦
Do not subject the battery module to high pressures.
◦
Do not place any objects on top of the battery pack.
A physically damaged battery pack should not be used anymore and disposed of properly.
Gui eline for optimizing your battery's life :
•
You can charge / discharge your battery in any manner with a compatible battery charger.
Li-ion batteries are not prone to memory effect. You do not need to fully discharge your
battery before recharging it.
•
NEVER leave your battery empty for storage. The battery's electronics require a very small
amount of current to work and will drain the battery after several months of storage.
•
To store your battery charge it to approx. 40 – 60 %. This will provide 4 to 6 months of
shelf life. Check the battery's capacity every month. f the battery reaches 20 % recharge it
to 40 – 60%.
•
The greatest effect on the self-discharge is storage temperature. Higher temperatures

increase self-discharge. Storage of cells and batteries in non-temperature controlled
facilities in hot climates can cause more rapid self discharge hence the storage method
plays a role in the shelf life of the product. For optimum shelf life store your batteries in a
cool place. You can store your battery in your fridge (3 – 4 deg celsius). We do not
recommend storing your batteries in a freezer.
Fuel gauge accuracy
f you were to observe fuel gauge discrepancy proceed as follows :
•
Fully charge the battery
•
Fully discharge the battery by connecting it to your equipement (i.e leave the battery cut off)
•
Fully recharge the battery again
Your battery is now recalibrated.
Embe e OLED fuel gauge (OFG) operation
1. Waking up the OFG from deep sleep :
f the battery has been in idle mode for a period of more than 90 minutes (i.e. no current draw)
the OFG will enter deep sleep. The OFG can be woken up by shaking the battery which triggers
the internal accelerometer and turns the display on. After 4 minutes the display will turn off
again and the OFG will enter normal sleep mode.
2. Waking up the OFG from normal sleep :
3. OFG dynamic information display :
The battery's OFG will start displaying dynamic SoC (State of Charge) information if the 2 following
conditions are met :
1. OFG is in normal sleep mode
2. The battery is connected to a load or charger and the current draw or input is > 50mA .
The OFG will always remain OFF if the battery is connected to an SMBUS compatible device. When
connected to a SMBUS compatible device (for example a DC current distributor, smart charger or
digital audio recorder/mixer with SMBUS capabilities) the host is responsible for retrieving battery SoC
information and displaying them to the user.

The OFG does not need to be woken up for the battery to supply power to the device it's connected
to. Power supply capability of the battery is fully indepedent from the OFG's status/operation.
Provided a battery is fully or partially charged (and not in protection mode) it will always supply power to
the device it's connected to even if the OFG is in normal or deep sleep mode.

Air transport / IATA regulations
Here is a short guideline for li-ion battery users :
• t is prohibited to carry li-ion batteries in checked-in baggages on civil airlines.
•
You may carry a « reasonnable amount » of li-ion spare batteries in carry on baggages if their
nominal wattage per hour is < 100Wh.
• All Audioroot eSMART Li-xxneo batteries have a capacity < 100Wh so you may carry any eSMART
Li-xxneo type of batteries in carry on baggages.
Warranty an Warranty Exemptions
AUD OROOT li-ion batteries have a 3 months warranty which covers any manufacturer defect.
AUD OROOT is not obligated to warrant eSMART Li-neo batteries, if defects are related to damages
caused by abuse/neglect, or from the following: - Damage from shipping or corroded terminals-
Manufacturer codes tampering or removal - Failure to properly install the battery, in addition to keeping
the battery properly charged and maintained - Breakage from collision, fire or freezing—which includes
damage from extreme heat or cold, improper storage, water damage, our warranty does not cover spent
or worn out batteries or tampering.
•
AUD OROOT will not be liable for any damages that are caused by violations of the precautions in
this user manual.
•
AUD OROOT will not be liable for any problems caused by design defects of the application and/or
chargers.
•
AUD OROOT will not accept any abnormal batteries that were caused due to any incorrect use.
