26650 Rechargeable Battery 3.7V, 5000mah

A growing number of electronic devices use 26650 Li-Ion batteries. Larger flashlights are using the 26650 battery to power current hungry 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 PKCELL 26650 5000 mAh 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.
