3.7V 1 2 Aaa Rechargeable Battery

[1x LED] 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!

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

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

[Hook & Loop] happy about it after i found rechargeable Sony AAA batteries already dropped it on water; still fine.

[58 mm (Front)] Youd think for the price this would have some flaws. At f.1/4 its pretty sharp at f.2 its razor sharp. I did not look at the outer edges of the frames as Im concerned with my subject. Good buy for the price.

[3x LR41] It's nice and bright and so glad it uses one AAA battery.

[NiMH] These are the best rechargeable AA batteries I have found. The AAA are the best also. They take a bit longer to charge but hold a charge better than any other I have found. Try them!

[12x AAA] The ZITHION-X AAA Rechargeable Batteries I recently purchased are very handy around the house. I especially like the way that no external charger is required. And it’s great to never run out of batteries.

[750 mAh] I bought a Coast headlamp that did not come with rechargeable batteries ,so you ordered a 4 pack of the rechargeable aaa batteries, I was and still surprised at how long they last and stay bright on full power .and since they are versatile unlike any other rechargeable headlamps I will continue to buy your great products. keep up the good work I look forward to what you will come out with.

[0.185 lb] Great light but getting the rechargeable battery will make you use it so much more often.
