www.TenergyBattery.com email: sales@tenergybattery.com All measurements performed to determine the electrical parameters in this datasheet
were conducted under the following conditions:
o Ambient Temperature = 25°C ± 5°C
o Relative Humidity = between 65% ± 20%
o Using Standard Charging current (0.2C)
o Discharge cycle started 30 minutes (rest period) after completion of charge cycle.
Charge and discharge cycles are noted using the parameter “C” which refers to the
capacity rating of the mentioned battery with units of 1/hrs. Hence, the charge or
discharge current is a fraction or multiple of the capacity of the battery, in units of
milliamps. The following table gives examples to demonstrate this:
For example if a battery has a rated capacity of 1300mAh:

Charging is performed using a constant-current/constant-voltage (CC/CV) charging
method. This charging method, generally, has two main stages:
o
o
Stage 1: Charge with constant current specified by battery datasheet. This is
performed until the battery voltage reaches the fully charged cutoff voltage, also
mentioned in the datasheet.
Stage 2: Once the maximum cutoff voltage of the battery has reached, charge
with constant voltage. The current should slowly decrease as charging
continues. Once the charging current has dropped to ≤ 5% (ideally ≤ 1%) of the
initial current value the battery is fully charged.
Storage:
Normal (Short Term) Storage: 28 days after fully charging cell (using standard charging method
and values), and stored at 25°C ±5°C, residual capacity ≥ 90% of nominal capacity rating.
Long Term Storage: 12 months after charging cell to half of rated capacity (using standard
charging method and values), stored at 25°C ±5°C, and humidity of 65% ±20%, discharge time
is ≥ 4 hours.
Transportation:
UN38.3 certified

Each of the tests in this section was conducted with a battery fully charged using
standard charging cycle parameters. Tests performed at room temperature unless otherwise
specified.
Test
Short Circuit
Impact Test
Overcharge
Thermal Shock
Drop Test
Testing Details
The battery is shorted by connecting the
negative and positive terminals to each
other using a copper wire with resistance
of < 0.05Ω.
Cell is placed on a hard surface and is hit
by a 10Kg hammer that freefalls from a
height of 1 meter.
Charge cell with constant current of 3C
until the voltage reaches 10.0Volts. Then
charge at constant voltage of 10.0V until
current reaches ≤ 0.01C.
Raise cell temperature at a rate of 5C
±2C per minute until a temperature of
150C ±2C is reached. Maintain this
temperature for 10 minutes.
Cell is dropped twice from a height of 1
meter onto a hard surface. This is
performed to all faces of the cell.

To prevent the possibility of battery leakage, excessive heat damage, fire or explosion,
please observe the following precautions:
WARNINGS!
•
•
•
•
•
•
•
•
•
•
•
Do NOT immerse the battery in water or other liquids. Keep or store the battery in a cool
and dry place/environment.
Do NOT use or store the battery near any source of heat.
Use a charger that is clearly specified to be compatible for charging the battery and has
appropriate charging protection (voltage, current, temperature)
Do NOT install the battery in reverse polarity.
Do NOT connect the battery to an electrical outlet or other incompatible power source.
Do NOT discard the battery in fire.
Do NOT short circuit the battery. Do NOT connect the positive and negative terminals to
each other with metallic object(s) or other conductive material(s).
Do NOT transport or store the battery together with metal objects, such as hairpins,
necklaces, or any other conductive object or material.
Do NOT strike, crush, puncture, disassemble, or throw the battery.
Do NOT directly solder the battery or battery terminals. Do NOT pierce the battery.
Lithium batteries should be used only with proper voltage, current, and temperature
protection circuitry and protection.
CAUTIONS!

•
Do NOT use or leave the battery in a high temperature environment (for example, under
direct sunlight or in a vehicle in hot weather). Failure to take this precaution can lead to
overheating of battery and/or fire or explosion. Also, performance of battery will degrade
and lifetime will be reduced.
Do NOT use battery in a location where there is high static-electricity or magnetic fields,
otherwise safety devices may be damaged which cannot be visible.
If the battery leaks and the electrolyte get into the eyes, do NOT rub eyes. Instead, rinse
and wash eyes with clean water, and immediately seek medical attention.
It the battery gives off an odor, generates heat, becomes discolored or deformed, or in
any way appears abnormal during use, recharging, or storage, immediately remove it
from the device or battery charger and stop using it.
In case the battery terminals are dirty, clean the terminals with a dry cloth before use.
Otherwise, poor performance may occur due to the poor connection with the instrument
or device.
Be aware that discarded batteries may cause fire or explosion. Therefore, apply a nonconductive tape to the battery terminals to insulate them before discarding.
