14500 Lithium Ion Rechargeable Battery

Please only add ONE battery to your cart with the purchase of a flashlight.  Shipping regulations require that we only ship batteries installed in a flashlight. We are not able to sell or ship extra batteries.  This battery requires a charger for charging.

This is the battery we recommend for our F2, F2R, F3, F4 and F4R.  It is a 14500 lithium ion rechargeable battery with a protection circuit.  That means that it has a controller built into it that stops it from over heating and over discharging.  Our lights have this protection built into the electronics on the the lights but the added safety is a great idea and makes this battery safe to use on other brands of flashlight that may not have built in protection.

It also has 1100mAh of capacity.  This is quite high for this size of battery and will give you great battery life on your flashlight.
