Battery Tips for LED Flashlight
1.Do not attempt to simultaneously recharge batteries of different capacities, different brands or different ages. Do not use batteries of different brands or different ages together.
2.Do not put single-use batteries in a refrigerator or freezer.
Some people in the battery industry assert that placing charged NiMH batteries in a freezer, if well-packaged to avoid collecting moisture, will enable them to retain a high percentage of stored energy.
3.Frozen batteries should be restored to room temperature before usage. Other experts discourage the use of refrigeration or freezing for any batteries.
4.This tip was previously stated, but it's worth repeating: If left unused for long stretches of time, recharge standard NiMHs every 1 to 2 months, precharged NiMHs every 6 to 9 months.
5.Remove batteries from devices if they will be left unused for months at a time. This prevents a device from exerting a tiny drain on the batteries even though the device is inactive.
6.Remove single-use (non-rechargeable) batteries from a device when they are being powered by household AC current. Doing so spares the batteries from any tiny drain on their power reserves by the device.
7.Do not store batteries, particularly single-use batteries, in locations where heat can become intense, such as car trunks, attics or garages.
8.Avoid tossing batteries into a drawer, briefcase or bag where they may contact metal objects such as coins or paper clips. Doing so may cause a short or it could negatively affect a battery's polarity.
9.Never put batteries into a fire. Doing so could cause them to rupture and spill their contents. Also: Avoid tossing them into a metal container where heat could build up.
