14500 Li-Ion 3.7V 800 mAh Rechargeable Battery High Capacity Flat Top  1 PC

Flashlights are using the 14500 battery to power high brightness LED bulbs, and to provide longer standby time when not in use. Previous rechargeable battery flashlights had to be left on the charger almost all the time so that it would be ready to use in a moment's notice. This 14500 Li-Ion battery can be left off the charger for months and still have over 90% of its charge. This enables you to charge an extra battery and have it ready to use in your flashlight in case you are going to be away from electricity for a long period of time or you forget to charge your original battery.

This battery is the same size as a AA battery, but do not use it in place of a AA. Since the 14500 fits into AA holders, many new projects requiring higher voltage are using this Li-Ion battery. It's more than double the voltage of a AA battery, and the standby charge versus other rechargeable batteries is up to three times longer. Save space by using three 14500 batteries instead of eight rechargeable AA batteries in a 12 VDC project.
