LITHIUM POLYMER BATTERY SAFETY
Before Charging Li-po’s
■
Before charging your battery check for any damage e.g. check if the battery has expanded or swollen
in size or if the battery cells have been punctured. If any of the above is true: DO NOT CHARGE THE
BATTERY!
Charging Li-po’s
■
Only use a charger designed to charge Lithium polymer batteries. Never use a nicad or other charger
as this is very dangerous.
■
Never attempt to charge at a rate faster than that recommended in the instructions. Check that the
battery
cell count matches the
charger
cell count switch (if fitted).
■
Never charge unattended. Always stay with your battery whilst charging in case of overheating or fire.
■
Charge on a safe surface or container (e.g. old unused microwave oven). Charge
only
on non-flamma-
ble surfaces, e.g. concrete floor preferably outdoors, or in a pyrex cooking dish with the battery placed
on a bed of sand, or in a fireplace. Never charge inside a car!
■
Switch off charger if battery gets too hot. If the battery becomes hot to the touch during charging,
disconnect and switch off immediately.
■
Extinguish fires with sand. If something goes wrong and your battery catches fire, always have sand
from a fire bucket at hand to douse the flames. Do NOT use water!
Using Li-po’s
■
Do not modify/change any part of the battery or lead. Do not remove its heat shrink protective covering.
Removal or modification may damage the battery and will invalidate any warranty claim.
■
Do not place this battery near fires or anything with high temperatures.
■
Do not charge batteries while you are driving and do not store batteries in any type of motor vehicle.
