RECHEARGEABLE BATTERIES
The burn-time of rechargeable batteries varies.
Burn-time is affected by:
(A) - Operating temperature – Do not use at highly elevated temperatures for extended periods of time.
(B) - Storage temperature – Store in a cool and dry place at room temperature (68-77° Fahrenheit / 20-25°
Celsius).
(C) -Time period the light was out of use. For extended storage, discharge a lithium-ion battery to about 40
percent (or approximately 1 hour on a fully charged battery) and store it in a cool, dry place. Warning: always take
batteries out of light when storing longer than 30 days.
(D) -Avoid completely discharging lithium ion batteries – Battery experts suggest that after 30 charges, you
should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a
condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery
discharge to the cut-off point and then recharge. The power gauge will be recalibrated.For safety reasons, do
not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several
months.
BATTERY DISPOSAL
Rechargeable lithium-ion batteries must be disposed of or recycled in compliance with all applicable laws.
Never throw into a fire, as batteries may explode.Keep batteries away from children
