C Size Rechargeable Lithium Batteries

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

[Ni-Cd, Ni-MH] 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.

[0.145 lb] ZX800 battery works just fine as do all Coast rechargeable lithium batteries.They offer decent run times and and std discharge while not being used is slow which is a good thing.

[0.095 lb] 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.

[0.025 lb] 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.

[0.5 lb] Performance with two disposable lithium batteries is average for the current market, but with the rechargeable battery it easily outshines much bigger devices. I'm impressed

[Clear] These have to be the best rechargeable batteries i've ever purchased. I have used them for photography with on camera flash before Godox came out with the lithium batteries. Have used these batteries until a plum war out and I couldn't recharge them anymore, they last a long time.

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

[0.1 lb] 18650-type lithium rechargeable batteries are very popular for high-powered LED flashlights. These batteries have a high energy content (up to 13 watt-hours) and are capable of high peak current discharge (up to 40 amps); they should not be stored loosely such that an accidental short-circuit could occur! This carrier is made of very tough, flexible rubber, about 2 mm thick. It securely holds the batteries and protects the battery contacts. Unlike a tray-type carrier, this carrier allows single cells to be removed or inserted without allowing the other cells to become loose. You can carry extra batteries in your toolkit or range bag without fear.
