1. General

This product specification describes the technique standards, test methods and precaution notes of prismatic type( Lithium ion) LiFePO4 rechargeable cell, manufactured by SHENZHEN TOPBAND BATTERY CO.,LTD.

2. Product specification(RT: 25±2℃)

3. Test Conditions

3.1 Standard Test Conditions

4.1.1 All tests defined in this Product Specification are conducted at temperature 25±2℃,humidity 15%～90%RH,atmospheric pressure 86～106kPa.

4.1.2 Unless there are other special instructions,all performance was tested with unused cells within 1month after production date.

3.2 Standard Charge Method

The "Standard Charge" means in an ambient temperature of 25±2℃,the cell was discharged with 0.5C constant current to cut-off voltage 2.0V,standing 1hour.Then charged it with 0.5C constant current to 3.65V,then change into constant charge mode,until the charging current down to 0.05C,then stop charging and standing 1h.

6.Precautions and Safety Instructions

Abusive use of (lithium-ion) LiFePO4 rechargeable batteries would cause damage to the cell and/or
personal injury.Please read the precautions and safety instructions below before using.

6.1 Standard cell precautions
a.Do not expose the cell to extreme heat or flame.
b.Do not short circuit, over-charge or over-discharge the cell.
c.Do not subject the cell to strong mechanical shocks.
d.Do not immerse the cell in water, or get it wet.
e.Do not disassemble or modify the cell.
f.Do not handle or store with metal objects like necklaces, coins or hairpins, etc.
g.Do not use the cell with conspicuous damage or deformation.
h.Do not connect cell to the plug socket.
i.Do not touch a leaked cell directly.
j.Do not mix the new and old Lithium-ion cell and use together.
k.Do not expose the cell to blazing sun (or in heated car by sunshine).
l.Keep cell away from children and pet.
m.Do not nail into the cell, strike it by hammer or tread it.
n.Do not impact or throw the cell.
o.Do not direct contact the cell positive and negative electrode with aluminum case.

6.2 Cell Operation Instructions

6.2.1 charging
a.Charge the cell in a temperature range of 0°C to 45°C.
b.Charge the cell at a constant current of 1C until 3.65V, and then at a constant voltage of 3.65V
until current is 0.05C.
c.Use a matched or recommend (CC/CV) lithium-ion (Li+) battery charger.

6.2.2 Discharging
a.Recommended cut-off voltage is 2.5V.
b.For maximum performance, the cell should be discharged in a temperature range of 0°C to 35°C.

9.2.3 Storage Recommendations
a.In case of long period storage (more than 3 months), storage the cell at temperature range of
–10~+30°C, low humidity, no corrosive gas atmosphere

b.Charge and discharge the every 3months is recommended, charge and discharge the cell every
6months is obligatory. Charge and discharge steps as bellow:
In temperature of 25±2℃, 1C discharge to 2.5V, stay for 30min,1C CC/CV charge to 3.65V cutoff
0.05C, stay for 30min,1C discharge to2.5V, stay for 30min ,1Ccharge for 0.5h.
c.To protect the cell, good storage environment is necessary.

Note 1.The customer is required to contact Shenzhen Topband Battery Co.,Ltd in advance, if and
when the customer needs other applications or operating conditions beyond those described in this
document.

Note 2.Shenzhen Topband Battery Co.,Ltd shall take no responsibility for any accident when the cell
is used under other conditions than those described in this specification.
