Tenergy High Drain AA and AAA Battery, 1.2V Rechargeable NiMH Batteries Combo, 8-Pack 2500mAh AA Cells and 8 Pack 1000mAH AAA Cell Batteries

All of the 6 double A and 6 triple A Tennergy batteries still hold a full charge. The performance of all 12 batteries is the same as it was 2 years ago. That's when I first purchased the set of 12 Tennergy 2500 amp batteries. I'm purchasing 12 additional batteries to completely switch over to rechargeable batteries. I don't need to replace any of the original rechargeable batteries. I purchased the first set in May of 2020. There still fast to recharge and hold their charge well. I like the performance and durability of the Tennergy rechargeable batteries over other brands that I had tried.

Tenergy is a decent Chinese manufacturer of rechargeable batteries and they're priced right too. I've purchased these a few times before and never had issues. Much, much better than the throw-aways that leak ending up with destructive white residue ruining the device it's powering.

These are 1.2 volt batteries, rather than the 1.5 that is standard for almost all electronic devices requiring batteries. Hence, the do not a hold very long. And, once I remove them from my charger, they seem to loose some charge (often enough that I keep needing to rotate them in the charger to alway have at least 4-6 fully charged batteries (AA, and AAA). But, if you’ve ever tried to buy rechargeable batteries at the local store, you’ll find prices such as 4 batteries for $16 or more. So, as a pain in the ass it is to keep them charged (with my 8 port machine), the value for the money is far superior ton that which you might find in nearly every store. I don’t believe their claim of 2500 mAH, but what the hell; I’m saving the environment just a little as I can. I’ve purchased this item twice so I am never without batteries. KFH.

Stumbled across these 14 years ago trying to find a product easier on the environment. Through the years, they have only improved. This was my first purchase needed in 10 years. Yes, 10 years, I still have some of the 14-year-old and several of 12-year-old in good working order. Thank you tenergy for making the weight and my families' footprints less. No other battery can compare. I refuse to purchase anything but Tenergy, Fortunately, their product is so well made I have not had to. Very rare to be able to give such a positive rating. I am very thankful to give feedback that is 100%++ longevity and environmentally progressive.

We had a major power outage here in Pennsylvania last year and these came in handy. I was able to run things with them for about 5 days before they started to die out (but I hadn't fully charged them to begin with) . These are a must have though if you live in an area where you have power outages because they will get you through for awhile , I've purchased multiple packs of them just in case. They hold a charge for a long time too.

I have been using these for a while. I really like them. Work in all my devices. Great way to save money in these tough times. Awesome Bundle Deal. Not my first purchase or my last.

These definitely seem to drain quicker than regular batteries do, particularly in electronics that use a lot of power. That being said, given the fact that they can be recharged several times (and quickly), especially for the price, I'm very happy with the purchase.

Came super fast and well packaged. Very easy to use. I plugged in using my phone charging cord and it charged really quickly. Love the lights that blink to tell me the charge level. This is my first set of rechargeable batteries and recharger.

Han trabajado muy bien hasta ahora los puse en una máquina para medir la presión y ocupa 4 baterías AA y consume bastante energía y no he tenido ningún detalle con ellas, las recomiendo

Muy buenas pilas recargable, duran bastante

Me fueron muy útiles para el trabajo. Las usé bastante. Lástima que algunas de la nada se chorrearon.

Las estoy usando para juguetes y controles, si dura la carga, no se, si porque son nuevas, buen precio, hay que esperar un tiempo

Bien
