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.

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!.

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.

*** Update: Changing my review to 4 stars. Even tho the diameter of the batteries is a little larger than the standard AA battery is and it they wont fit into my drink mixer, they still work fine in most things . The seller took care of me after learning of my issue. These batteries do pretty well, i learned about them on the Youtube channel called project Farm, and the project farm guy reviewed several batteries and these scored pretty high, which is why i bot them. cheers **** Batteries charge up fine and power devices well, the problem is the Diameter of the battery. For devices where the battery fits into a definded space these batteries will not fit . My drink mixer has holes where an AA size battery barely fits into. These PowerOwl batteries will not go in, unless your force them... and then its almost impossible to get them babck out once they need recharged eventually. I got out my digital calipers and checked the diameter of a regular alkaline duracell and rayovac AA battery and they are both .542" diameter, these recharable PowerOwl AA batteries all measured close to .570". They are fine if they do not need to go into a tight defined space. Apparently the manufacturing tolerances where these batteries are made in china are not as tightly controlled as where they make name brand batteries like Rayovac or Duracell etc....

These are a family favorite! I've been using my other ones I've a few years and decided to grab some more. I love them and that they hold a nice charge after being used literally hundreds of times :). Takes several hours to charge them but they last after charged. They will get a little warm on the charger so I always make sure to remove them right away and let them cool off before using them in something. No issues with any though. I recommend. Make sure you have the charger!

I order the Powerowl Battery about 2 year ago and I like them, now for my Christmas Decorations I needed more of Battery and since there are lasting long and you can recharge them I order more. A bit pricey but it is worth the money and are good

Cargando muy bien

Production batch issue, finally got to use them and recharge for the first time, they would not take charge at all, tried with 2 chargers and still wouldn't take charge Seller reached out to rectify the issue, top notch warranty and CS for sure New batteries are yet to test, but added 4 stars (from 1 star to 5 star) for CS and warranty support, and replacement are good quality so far, 1.38v to 1.42v fully charged

these bad boys have been in my daily arsenal since i bought them. the capacity seems to be correct cause they last a long time. longer than my ikea rechargables with a lower capacity and these are much cheaper

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

They work well
