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.

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

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.
