I realize the 20 pack isn't ideal for everyone, but when your thinking long term game to replace non-rechargeable batteries throughout the home this is a good option! I bought this 20 pack around 10 years ago and I'm still using most of them. I don't have any flat out failed batteries yet, but two of them are quite faded and cannot be used in large load situations. Most of my batteries get used in low energy consumption motion detection lights which typically get used at night when wandering from room to room. When they were new they could go months without a recharge, but some of them need a recharge about once a week or once every two weeks depending on how much sun is flooding the room (which negates the motion detection light turning on). Even at 10 years of age most of these batteries can power mid power consuming devices such as multiple servos running in parallel which some modern robot toys have within.

My only complaint about these batteries is the shrink wrap shell it is protected by seems to be fragile against rubs and bumps. Once that shell is penetrated it can cause an undesirable circuit depending on the device it is installed in. Its mostly the shoulder around the positive tab region that is mostly concerning. It is my opinion that larger C and D batteries of any brand should take better care in providing non-conductive material there which can take a strike from the external elements. The batteries are naturally heavy so they will bump into things and momentum and mass will cause adverse effects.

They're extremely reliable so long as they don't get abused or neglected. None of them are leaking and none of them have failed on me. I would go this route again to replace my aged set, but I think I'll give the low self discharge version a try soon! Are these worth it, yes, yes they are!

i have bought these for a couple years--- about 25% of them only last a year or so - wished they would last longer before they won't recharge anymore. They are kind of expensive and I need alot on hand to run several trail cams,but it beats ordering non rechargable batteries all the time.

Have had these batteries for at least a year now and still going strong. I have a charger and they respond to the charger wonderfully. I am buying more because I have so many items that require these batteries. Thanks for a good product.
