Rechargeable Battery Li-Polymer Battery Cell Rechargeable Battery 3.7v 600mah Pack Model Quality 502060 Small Lithium Polymer Batterie Lipo 3.7v 600mAh KC Certified Batter

• Load circuit may cause voltage and current, and the voltage or current may add to pack, the voltage or current must be              controlled as lower than RWV and RWI, larger voltage or current may damage the PCM of pack.
• To prevent the possibility of the pack from leaking, heating, fire .please observe the following precautions: 
• The soft aluminum packing foil is very easily damaged by sharp edge parts such as Ni-tabs, pins and needles .
• Do not strike at pack with any sharp edge parts.
• Do not immerse the pack in water and seawater
• Do not use and leave the pack near a heat source as fire or heater
• When recharging, use the battery charger specifically for that purpose 
• Do not reverse the positive and negative terminals
• Do not connect the pack to an electrical outlet
• Do not discard the pack in fire or heat it
• Do not short-circuit the pack by directly connecting the positive and negative terminal with metal object such as wire
• Do not transport and store the battery together with metal objects such as necklaces, hairpins etc.
• Do not strike or throw the pack.
• Do not directly solder the pack or battery and pierce the battery with a nail or other sharp object. 

FAQ:

Q: Can I use Lithium batteries mixing with other battery types?

A: If different types of batteries are used together, or new batteries are used with old ones, the difference in characteristics of voltage, capacity, etc. may cause over-discharge of the battery which is exhausted first, leading to swelling, bursting or fire.

Q: What will happen if the batteries with different capacity are packed together?

A: If the batteries with different capacity or new and old batteries are used together, leakage, zero voltage and so on might happen.

If the batteries are rechargeable and are being charged, some batteries are overcharged and other batteries is not in full charged state.

During the discharge, some batteries cannot discharge fully and other batteries might over discharge. This way, the battery will be damaged.

Q: What are the possible reasons for zero voltage or low voltage of the battery pack?

A: Short circuit or open circuit of the connector or wrong connection, de-soldering or cold solder joint between the batteries and lead, wrong connection between the batteries.

Q: What are the possible reasons if the rechargeable battery or rechargeable battery pack cannot be charged?

A: The battery is zero voltage or there is battery with zero voltage in the battery pack.

There is wrong connection inside the battery pack.

There is abnormally of electronic components and/or PCB inside the battery pack.

There is failure in charger.

Outer element causes the charging efficiency to be too low, such as extremely low or high temperature.
