1.5 Volt Lion Aaa Lithium Rechargeable Batteries

The rechargeable lion battery that comes with the XP11R is the only way to go. Reason is simple. It has power to use the turbo feature. That is what makes the XP11R special. It is also very convenient to charge the battery while it is the flash light. I would strongly recommend get at least one spare battery from Coast for these reasons. If you go camping you will have extra power or if your current battery ages and all rechargeable batteries do you have a spare battery. What I did was to get a spare battery and a an extra light: I will probably get one more extra battery for the XP11R. That way I will have two lights two spare battery batteries.

I already had two of the Nikon EN-EL15c Rechargeable Lithium-Ion Batteries, but I recently purchased the Nikon MB-N11 Power Battery Pack with Vertical Grip for my Z7ii which takes two of the EN-EL15c batteries, so having a spare made sense to me. I also own several EN-EL15 batteries for my D850 and have experience zero problems with Nikon batteries.

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

This light is compact, very bright, and uses common AAA batteries instead of the more costly lithium ion rechargables. Overall a great little light for use around my shop. The only thing I don't know yet is how long the LED will last. However as a guide, I have had a 4 DCell LED Maglight for around five years and it's still going stong.

I had origianlly been using 8 AAA bateries and they ran down quickly. This Lithium battery is definitely a upgrade to a handful of AAA batteries.

This is my first time purchasing rechargeable Lithium Ion batteries with a built-in USB charging port. That's a very convenient way to charge the battery especially if you forgot the adapter at home.

I purchased this, not for analyzing rechargeable batteries, but for measuring capacity of several different brands of lithium AA batteries. There is a common knockoff of this product that didn't actually work for my use case, but I did use it for charging batteries, and I can say that the user interface of the Powerex is much more intuitive and easier to use. As far as customer service, I emailed Powerex to find out if this would do what I was trying to do, and a representative called me and let me know that while it is not an officially supported use, it would work, which proved to be true. I would definitely buy more products from them after having that experience.

Coast’s lithium battery ZX450 all batteries that Coast supply are excellent. Reason I say this is because rechargeable lithium batteries sometimes have issues like premature failure. Things like not taking a charge, memory issues, and short run times to name a few. I do handle lion cells as recommended which is important for long life. Coast batteries and my lithium cellular batteries are the only batteries that work as promised regarding rechargeable lithium cells. I expect an a dramatic improvement with rechargeable lithium batteries of all sizes any time.

50W is very loud! Lightweight Lithium Ion rechargeable batteries. Very easy to use. I especially like the 10 second built-in memory.

I have used Watson lithium rechargeable batteries for years in Nikon, Fujifilm and Pentax cameras. No problems with battery life, recharging or performance.
