POWEROWL Rechargeable AAA Batteries PRO, High Capacity 1100mAh, Premium NiMH Triple A Battery -16 Count

I switched to PowerOwl PRO Batteries. Feb 2024 and ALL are still WORKING Good.Since Feb 2022 to Oct 2023,I bought Tenergy Solla(2) 12 AA Batteries,(1) 24 AA Batteries,(2) 12 AAA Batteries,Total of 72 Batteries .I have about 24 that are still working.Some didn't hold a charge, the rest stopped charging .

Love these batteries. They work as advertised.- They won't leak battery acid like normal batteries, so you never have to worry about battery acid ruining yourelectronics.- In the long run, they save money because you don't have to keep purchasing new batteries.- These batteries when fully charged will last longer before having to be replaced in your devices.I liked these so much that I have AA, AAA, C, D, and 9 volt rechargeable batteries

Why did you pick this product vs others?:Love the charger, charges batteries individually, my other charger only charges if 2 batteries are in it, only thing I don’t like is the usb micro port since those ports are horrible and always break or get loose, I’ll be careful with it and probably never unplug it because other than that it’s a great battery charger, I can’t speak for the batteries yet, hopefully they last a long time.

the power is nice however they don't hold they self discharge sooner than expected. For the price a they were a good purchase. They fit in all my devices exactly like a standard AA. The performance increased after several charging cycles. While they work in every device iv'e tried them in some devices are not capable of displaying % of charge level.

I have changed my below review because of their great customer support! I would consider them again because if there is a problem the company will take care of it. They gave me a full refund."First time buying and first time charging, some of the AAA took a lot longer to charge. Noticed one had acid leaking on top. I searched about contacting the company and I finally found a number and a name but who knows if I will reach someone. Won't purchase again because they don't compare to my other recently purchased Eneloop and EBL which are cheaper anyway. Added to this now 2 have went acid!"

Excellent rechargeable system. Changes pretty quickly and that batteries last a good long time. We use them for remote control candles throughout the house and they are the best for this.

So far so good! Works well with circular charger.

It is now the end of November 2024. I bought these Powerowl brand batteries in December 2023. I had a Powerowl brand charger that I bought in 2019. I recharged these Powerowl batteries using the Powerowl charger. I labeled the individual batteries with the month and year I bought them and an alphanumeric designator to tell the batteries apart, so I know I haven't used the same ones every single time. Plus, I haven't recharged any of them every single day, so there's no way any of them are approaching 400 or 500 recharge cycles. I'd be surprised if any of these batteries have been recharged even 100 times. It would have been nearly impossible to do so unless I were using a very high drain device all day long. Probably about 4 to 5 of the batteries now indicate that they are not working properly and do not hold a charge or recharge. They are not being used in extreme conditions. I don't know for sure if it is due to a malfunction with the Powerowl batteries or the Powerowl charger. I suspect it could be a problem with the Powerowl charger, since multiple brands of rechargeable batteries (brand new Energizer rechargeables, slightly older Energizer rechargeables, older Rayovac rechargeables, older Duracell rechargeables) have ceased to function after I used the Powerowl charger to recharge them a few times. I am using different rechargeable battery brands and different chargers for those batteries now. In the case of batteries that I had already used the Powerowl charger to recharge, I will continue to recharge in the Powerowl charger, especially the Powerowl branded batteries. I am disappointed by the performance of one or both of the Powerowl products. It could possibly be a malfunction only with my particular Powerowl charger unit that could only be known after use, but even off-brand rechargeable batteries are more expensive up front than regular batteries, and it is less eco-friendly and less frugal if the rechargeable batteries function less than 100 times before ceasing to work properly. I don't know how much the Powerowl batteries can then be recycled, but I hope they are not ending up in a landfill.Also, these Powerowl batteries are slightly bigger in circumference than most other single-use or rechargeable AA batteries, and they do not fit in some battery compartments.The good aspect of these batteries is that when charged, they do last a long time in most devices, several days or weeks, most of the time. However, the fact that so many of these Powerowl batteries have not managed to function for a whole year and have malfunctioned with fewer than 100 recharge cycles is disappointing, to say the least. The question remains as to whether it was the fault of the Powerowl batteries or the Powerowl charger, or both.If you bought the Powerowl charger unit with Powerowl branded batteries on a good deal, I think that could be saving a bit of money and a little bit of the environment versus buying regular single-use batteries, but I would be hesitant to put any other brand of rechargeable batteries in the Powerowl charger. I don't know what other users' experiences are with these batteries when using a different charger than Powerowl brand.It is frustrating that few brand name chargers charge more than 4 batteries at once in one charger, and many of them don't charge odd numbers of batteries or single batteries. However, some name brands do make chargers that do so for up to 4 batteries, and the name brand rechargeable batteries seem to last longer when using their same charger brand, though they are generally more expensive than the off brands. If you can get the name brand rechargeable batteries with the name brand charger on sale, ultimately you might be saving money and the environment a little more.UPDATE (05 December 2024): The seller contacted me on 01 December 2024, the day after my review of these batteries was posted to Amazon. The seller offered a full refund, apologized for any inconvenience, and expressed hope that I would give them another chance. I appreciate the gesture and am inclined to do so in response to such great customer service. Perhaps I will use any money refunded to purchase another Powerowl charger with Powerowl batteries and see if they have the same issues. I will update my rating of the batteries accordingly if I do not have the same issues with another batch, but for now I do not want to rate the batteries higher than a 3-star rating. I wish I could give 3 1/2 stars, pending further evaluation. The *seller* gets a 5-star plus rating for customer service and response, however.UPDATE (07 June 2025): I have been recharging the Powerowl AA batteries in an EBL charger I had already had. At first, it recharged some batteries that the Powerowl charger had not charged properly, and they worked great for a while. Now, many more batteries are not working properly and lose their charge immediately. It may be a malfunction of the EBL charger. I don't know why two different chargers would be malfunctioning, but appliances and other things often malfunction in my current residence even when plugged into surge protectors, so perhaps it is the ever improperly employed "sh*t fairy" visiting my residence in order to break things, and not actually a problem with the products themselves at all. It's difficult to determine the problem accurately under current conditions.
