what type of battery is needed?

I bought the "IntsunUltraFire 18650 3000mAh 3.7V Rechargeable Li-Ion Battery (Pair) + Charger Combo". It was $10.80 delivered with my amazon prime. They hold a charge well, rated at 3000mAh. they charge fast, and the charger's compact with no parts to lose. I paid $39.00 just for a light that wasn't nearly as bright before this so in my opinion, this light battery combo can't be beat! Especially when you get two of the batteries. Hope this helps you.

The item has a built in rechargeable battery. No need to replace battery, but I do not know the model. That would be a question for the seller.

Any AA batteries will work, I used regular ones and they are still working two months later

My understanding is that it is the type of battery. The SL requires the slide-type battery.

2 - 3Volt 123A Batteries. You can use any type but I prefer the Surefire Brand myself.

You can purchase batteries here on Amazon or the following locations: Radio Shack, Best Buy, Batteries +, or any battery supply house.I would suggest that you do a Google search for the size / type of battery you need followed by your zip code. This will give you local options as well as internet suppliers.Enjoy - Mark

You should use a 8.4V mini battery pack and its not that hard to install. There are many videos on youtube you can view to show you how to install the battery also.

The battery is a backup in case of power interruption. From a practical viewpoint you need a low voltage power supply.

The batteries needed are two D cells, preferably alkaline. A set of batteries should give you 20-25 hours of running time.

A battery and charger. If you look at some of the reviews you'll find suggestions for third-party battery-and-charger kits.

I purchased one last Christmas. I don't remember what kind of batteries it needed. It did work great.
