POWEROWL AA Rechargeable Batteries, 2800mAh High Capacity Batteries 1.2V NiMH Low Self Discharge, Pack of 16

Updating 11/14/25: Company messaged me and offered full refund after seeing this review. I was going to accept. Then discovered these are 1.2v not 1.5v. I automatically assumed voltage was same in AA and AAA batteries. Rechargeables are different. My bad. Outstanding customer service deserves 5 star and batteries are working great now that I understand. Kinda disappointed in how long charge last. I bought a bunch of various sizes based on an extensive youtube review. They sure seem to poop out pretty quickly compared to non renewable major brands. They do charge to their full voltage measured on my multi-tech.

This past Christmas of 2023 I have decided to do something different. We have no streetlights and our yard is very dark until the spotlight goes on. Being here for 13 years we have never set up Christmas lights outdoors, mainly due to the cost of electricity. Well, to brighten up this past Christmas and future Christmases I invested in solar-powered Christmas lights in various sizes that have Ni-MH rechargeable batteries varying from 400-1200mAh. The downside of these lights is that they carry the lowest capacity batteries that operate the lights for the advertised run time. In the majority of the 14 sets of lights, these did not meet the advertised run time. That is mainly due to the lack of 6 full sun recharge time required. In my area, that is impossible due to tree shade in the summertime, and in the winter when there are no leaves the sun peeks through in and out the tree trunks and branches so these lights don't get that full sun necessary to operate for at least 6 hrs advertised. I had lights in this scenario operate only for 1-3 hours. Another downside is cloudy days. On cloudy days mine as well forget the lights. The solution was to get replaceable Powerowl Ni-MH batteries with much higher capacity and a Powerowl recharger. I got 32 AA2800mAh to replace the batteries that ranged from 400-1200mAh. The new 2800m batteries after fully charging them in the house stayed on all night until the daylight turned off the lights. The following day there was very little sun but these lights stayed on another night until daylight turned them off. I got another set of 32 batteries and hold it as a backup this way I will always have a full supply to replace all batteries in 14 sets of lights. I also wanted to utilize the batteries that came with the lights and started to recharge them. I had 8 400mAh and the recharging indicator red light was blinking. Not knowing what that meant I reached out to the support at Powerowl and asked why the indicator light was blinking. Their first suspicion was the batteries were too low of a capacity at 400. To confirm this they asked to send a picture of those batteries. After reviewing the pictures the company responded quickly stating that these were too low of a capacity and they felt sorry that I could not use these batteries with their recharger but to keep a customer happy they offered to send 8 AA2800mAh as a consolation for my troubles free of charge. Additionally, the rechargeable batteries have improved greatly. The older versions of rechargeables were limited by their memory. The new rechargeables have no memory and these can be recharged as much as 500 times. With the cost of other brand-name, batteries range anywhere from $1.50 per battery in a pack. The rechargeable batteries cost about the same per battery but the brand name once they run out we throw them away while the rechargeable can be recharged and keep on going. I plan to convert all brand-name throwaway batteries in all devices that have batteries in the house and never buy a brand-name battery.

Who doesn't need batteries, right....?!? Ironically, I purchased the WRONG, SIZE....as I purchased these while I was away from the item(s) that I was initially purchasing them for: space saver -cabinet lights! (We have over 20 lights [4X batteries in each]) throughout our RV, and the cabinets/utility spaces in our home. Nevertheless, we needed AAA BATTERIES, but as I mentioned, earlier; I purchased the AA batteries,...AT FIRST!! Well,...after realizing my mistake, I went ahead and purchased the correct ones; AAA! But never fear, for as I asked; WHO DOESN'T NEED BATTERIES,...RIGHT...?! The AA batteries were used in 2 of our HIGH LUMEN,...handheld & portable flashlights,...as well as several of our remote controls (T.V.'s, stereos, peripherals, etc.) The POWEROWL brand offers PLENTY of value for your money! Lots o' power! Slow drain/discharge. Super easy & quick recharging times, too! Definitely can't go wrong, here!.

After researching I paid a premium for these batteries and wanted to say these batteries don’t hold a charge very long and some won’t even charge anymore. I’ve charged them only twice. I’ve only had these batteries for 5 months. UPDATE: The company reached out to me and sent me another package of batteries as a replaced. Fantastic customer service. Thanks!!

I use these for my gaming equipment and work equipment - last a long time and holds a change better than my other rechargeable batteries. Does not heat up too much during charging, fits AA slots easily.

I was a little skeptical because of the price but after much use these batteries have preformed very well. I use them a lot in my Xbox controller and for other everyday items that require batteries. The really nice feature that I didn't even think was a big deal at the time was the ability to charge both AA and AAA batteries together in the same charger. Extremely convenient. Every time I am in the store and I see those big packs of batteries I am always reminded how expensive that was and kind of mad at my self I didn't purchase this earlier.

Great batteries

I bought 2 sets of these 12 pack cause of good rating and performance. They worked just fine. I alternate/cycle thru these batteries for daily use. But I find that every time I had to recharge them, the Amazon Basics battery still has 40%+ charge remaining, while these were down to 0%. The Amazon batteries were older. I thought Amazon brand was generic batteries. I did some research and found that Amazon batteries has higher capacity, low self discharge, and hold a charge for up to 2 yrs & up to 1,000 charge cycles. So much for buying these overrated brands. Sticking with Amazon for now on.

Cargando muy bien

I was tired of replacing regular batteries especially in my Christmas decorations so chose to go to reusable batteries. Love them! I had a charging issue with a couple of them but Powerowl customer service was excellent in replacing them promptly.

This is my second purchase. good batteries comply with ña description

Funcionan pero no cumplen con la capacidad que ofrecen, cicladas con un cargador hitec a 0.9 volts por celda

They work well
