Lithium Polymer

Rechargeable Batteries

GMB Series from 100mAH to 10,000mAH

www.powersolve.co.uk

Lithium ion polymer batteries are the new generation lithium ion
batteries. They not only give the same high voltage, long
recharge life, steady discharge rate and pollution free as liquid
lithium ion, but also eliminate the safety hazards associated
with these type of batteries. The battery design becomes more
flexible, convenient, light and easily moulded into a specific
size requirement. The performance has reached or exceeded
the technology parameters of liquid lithium ion batteries with
better reliability.
Applications include communication equipment, mobile phones
and radios, portable computer equipment or instruments, digital
cameras, camcorders, LED lamps and any equipment where
small size and high power density are important.

Note: All batteries above can be supplied in multiple packs to increase voltage or current. Custom sizes
can also be accommodated but these will be subject to tooling charges and minimum order quantities.
Consult sales office for details. All cells and battery packs are provided with Protective
Circuit Modules (PCM) to protect against over charging, over discharging and over current.

Handling Precaution & Guidelines

Charging Current The charging current must be less than the maximum charge current specified in the electrical

Charging Voltage The charging voltage must be less than the maximum nominal voltage 4.2V and the charging

Charging Temperature The cell must be charged within the range specified in the electrical specification

Reverse Polarity Since charging is done with a constant current or a constant voltage, reverse charging is prohibited. If

Discharging Current The cell shall be discharged at less than the maximum discharge current specified in the electrical

Discharge Temperature The operating temperature when discharging the battery should always be within the range specified in

Over Discharge Over discharging will cause cell degradation and functional losses. The cell can degrade into an over

the electrical specification

discharge state through self discharging. In order to prevent this the cell should be charged periodically
to retain between 3.6V and 3.9V

Cells should be used with a PCM that can protect against over charging, over discharging and over
current

If cells are to be stored for 3 months or longer they should be held in a dry cool environment. Voltage
during storage needs to be maintained between 3.6 and 3.9V. If stored for long periods keep in a half
charged state

• Avoid any short circuit, it will cause the leads to get hot and lose electronic functions

• Packaging is easily damaged by sharp objects. Avoid touching with sharp objects during handling

• Next to leads is sealed edge, Don’t bend or fold sealed edges it is sensitive to movement

• Don’t open the folded edge on the side of the cells

• Don’t bend the tabs as these are sensitive and could be damaged

• Avoid mechanical shock to the cells

• Do not place cells in an oven, washing machine or high voltage container

• Use only recommended charger

• You should immediately stop charging if cell overheats, emits odour, changes shape or colour etc.

• Adults should supervise the use of batteries by children

• Before using batteries carefully read and understand handling guidelines.

• Avoid electro static discharge when using, charging and storing cells.

• Avoid accidentally putting battery in contact with metal conductors, which may cause a short.

• Don’t short circuit battery output terminals during assembly

• Never incinerate or dispose of the cells in a fire
