These batteries are the Premium Intelligent Series Computer-Protected Lithium Ion Rechargeable Battery.
I know that’s a mouthful, but here’s why we use these batteries in our own lights and why you should too…
In short, Intelligent Series Batteries utilize “Smart Circuitry”, which prevents the battery from being overcharged, overheated, and overdriven during both recharge and flashlight operation cycles.
This protective circuitry combined with a Grade A Premium Lithium Build, make for longer run-times and increased battery cycle life.
You won’t have to worry about battery leakage (Battery acid that creates a nasty white crust that forms around batteries.)
You’ll save money because you won’t be replacing batteries all the time due to constant overcharging.
These batteries will outlast the cheap batteries so you won’t have to worry about your light failing you after a few minutes of run time.
Includes two batteries per pack.
