This hand power flashlight contains a bright LED light that never needs replacing. Shock and water resistant, the shake LED flashlight is durable and tough for any outdoor activity. Outstanding performance combined with a great price makes a shake LED flashlight a great buy. Buy the shake LED flashlight online or call 800-479-6334.

To determine battery life, simply divide the capacity by the actual load current to determine the hours of life. A circuit that draws 10 ma powered by a 9v battery life is roughly 50 hours. (500 mah/ 10 ma) The cell voltage of alkalines decrease with usage from about 1.5 volts to around 1.25 volts when half discharged. The voltage is around 1 volt when the battery is discharged.

It is also noteworthy that alkaline batteries exhibit a slightly increased capacity when warmed and the capacity significantly drops at temperatures below freezing. Lithium batteries perform better at extreme temperatures and should be used when applicable.

It is best to keep this in mind when choosing a battery for a particular device. If you have any questions on which battery to use, do not hesitate to call the experts at Medic Batteries at 800-479-6334.
