Usage & Precaution:

Lithium-ion and lithium polymer cells are powerful batteries; you should take extreme care when using them. If exposed to abusive conditions, they may get hot, explode, or ignite and cause serious injury.

Unfortunately, we can not replace batteries damaged by non-compliant chargers or equipment.
Be sure to follow the safety warnings listed below:

Do not

• Overcharge: Ensure the charger voltage does not exceed the battery’s full charge voltage.
• over-discharge: Ensure the equipment you use this battery will not draw more current from that battery than the stated “Maximum Continuous Discharge Current.”
• leave batteries discharged for an extended period can incur irreversible damage
• by placing the battery on fire, heating, or direct sunlight to the battery.
• Install the battery backwards so the polarity is reversed.
• Connect the battery’s positive and negative terminal with any metal object,
• expose the battery to water or saltwater, or let the battery get wet.
• Disassemble or modify the battery. The battery contains safety and protection devices.

Additional safety notes: Do not use a NiMH/NiCad/lead-acid charger! Also, never charge or use unattended. Always inspect batteries and surrounding circuitry constantly for damage, loose wiring, or the possibility of short circuits.

As with all Lithium-ion polymer batteries and any power source, they should be used by experts who are comfortable working with power supplies.

Note:  Please check your current cable orientation, as there is no  Industry Standard for Cable setup. Wrong orientation can damage the cell and your item.
