Thank you for your purchase of an AUDIOROOT 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 fu-
ture reference.
Embedded OLED fuel gauge (OFG) operation
1. Waking up the OFG from deep sleep :
If 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.

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 contain ammable items
such as organic solvents. If the battery is mishandled, it may
cause re, smoke or an explosion and the battery’s functio-
nality 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 come 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 any-
more and should be disposed of properly.
Guideline 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. If 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 faster 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
If you were to observe fuel gauge discrepancy proceed as
follows :
• Fully charge the battery
• Fully discharge the battery by connecting it to your
equipment (i.e leave the battery cut off)
• Fully recharge the battery again
Your battery is now recalibrated.

Air transport / IATA regulations
Here is a short guideline for li-ion battery users :
• It is prohibited to carry li-ion batteries in checked-in
baggage on civil airlines.
• You may carry a « reasonnable amount » of li-ion spare
batteries in carry-on baggage 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 baggage.
Warranty and Warranty Exemptions
AUDIOROOT li-ion batteries have a 3 months warranty
which covers any manufacturing defect.
AUDIOROOT is not obligated to warrant eSMART Li-neo
batteries, if defects are related to damage caused by abuse/
neglect, or from the following: - Damage from shipping or
corroded terminals- Manufacturer codes tampering or re-
moval
- Failure to properly install the battery, in addition to keeping
the battery properly charged and maintained
- Breakage from collision, re 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.
• AUDIOROOT will not be liable for any damage caused by
violations of the precautions in this user manual.
• AUDIOROOT will not be liable for any problems caused by
design defects of the application and/or chargers.
• AUDIOROOT will not accept any damaged batteries if
caused by incorrect use.

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 capabi-
lity 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.
