1.2 Volt Aaa Rechargeable Battery 500Mah

The light is easily the most powerful pen light I have ever owned. I also really like that you can use a rechargeable battery or two AAA batteries. The build quality is excellent, I have dropped mine numerous times and there is no problems. Definitely a high quality product. One of my coworkers bought one as well after seeing how good mine is!

I ended up using this receiver. It takes rechargeable AAA batteries which is more economical that than the battery in the ShutterBoss lll receiver.

The pen accessory for my tablet drains the necessary one AAA battery. A rechargeable battery was required. I also bought the charger with the four AA batteries. I carry a few charged batteries with me. Works out well.Price better than @.

Hi, Upon receiving the rechargeable battery, I charged it up. I then removed the supplied 3 AAA batteries from the headlight and placed the rechargeable battery in. It fit perfectly and worked perfectly! Thank you and keep up the good work. Nothing like having a good rechargeable battery and if ever in a pinch, I can always put in the 3 AAA batteries.

If you use rechargeable AA's or AAA's, you should have a decent charger. Most chargers charge in banks of 2 or 4. That means that the battery will be treated the same as its neighbor. Better chargers charge each battery independently of the others. This way, the batteries get what they need. The best chargers give you metering on each battery. I've always had good luck with Watson products. This charger keeps the streak going.

happy about it after i found rechargeable Sony AAA batteries already dropped it on water; still fine.

Unbelievably bright for one AAA battery!

worked just like the product I replaced except uses a double A battery instead of a nine volt.

First impression was not good, kind'a dinky...� Well I put one of my rechargeable AAA's in it to make sure that would work.� It does come with an alkaline AAA battery, but I am interested in using a rechargeable with it so I had to see.� So wow, this little dinky motha is for real.� It's amazingly bright for it's size, it is well made so it turns on crisply with a twist of the front end.� It also looks to be durable but now time will tell if it will hold up.� I think it will as it's aluminum construction and excellent machining project durability and functionality.

It's nice and bright and so glad it uses one AAA battery.
