Rated 5 out of 5

A must-have accessory.

This is, simply, a spare battery. In other words, it makes sense to purchase and keep it handy for when you need it.

Works great!

It’s a battery, it does what a battery does. I do like the fact you can run the light with both the battery and AC power. Mire options are always better
