Lithium ION/POLYMER Battery Safety Warnings

LITHIUM ION/POLYMER BATTERY

SAFETY WARNINGS

Ensure that the charger and battery are placed on a non-flammable surface whilst charging and ideally charge outdoors wherever possible. NEVER charge a Lithium ION/Polymer/Fe battery inside a vehicle whatever the circumstances.

ALWAYS ensure that the charger is correctly set for the battery being charged, checking both voltage and capacity. Be particularly careful if using a series/parallel battery pack, or if using packs of different specifications with the same charger.

NEVER charge at a rate higher than that recommended by the cell manufacturer, this can be very dangerous.

DO NOT leave Lithium ION/Polymer/Fe batteries unattended whilst they are charging. Monitoring the batteries during charging is very important.

ALWAYS monitor the temperature of the battery being charged every few minutes. If the battery becomes hot to the touch, disconnect it from the charger immediately and allow to cool. DO NOT recommence charging until the battery and charger have been checked for compatibility and the charger settings have been confirmed as being correct.

In the unlikely event of the Lithium ION/Polymer/Fe battery catching fire DO NOT use water to attempt to put the fire out, instead use sand or a fire extinguisher designed for electrical fires.

When used correctly, Lithium ION/Polymer/Fe battery packs are as safe as any other type of rechargeable battery pack.However they do require different charge regimes to the longer established Nickel Cadmium and Nickel Metal Hydride technologies and have the potential of catching fire if severely mistreated.

If Lithium Polymer battery packs are short-circuited or severely over-charged elemental Lithium may be deposited internally, and if the battery pouch is damaged this can escape from inside the battery. If this occurs a fire may be caused, as elemental Lithium is highly reactive when exposed to water or moisture, producing flammable hydrogen gas and corrosive fumes. Elemental Lithium is not produced unless the battery pack is severely mistreated, so in normal usage there is no likelihood of explosion or fire.
