EBL Rechargeable AA Batteries, 4 Pack AA Lithium Batteries 1.5V 3000mWh High Capacity Double A Battery...

These batteries take a charge quickly in the accompanying charger. Once charged, they hold the charge well in storage. The 3000 mAh batteries are more powerful than most rechargeable batteries, which is one of the main reasons I bought them. I was very happy to see how quickly they took a full charge. The charger indicates the state of charge of each individual battery. I took the accompanying photo after all batteries were at full charge. When one or more of the batteries is not fully charged, the LED light will show red, instead of the green shown above all the batteries in my photo. I have used these to power strings of LED lights and to power a computer mouse. They worked well in both applications..

Bought these because I was sick of spending a ton on Energizers. Cost is good compared to them and the are rechargeable so cost will be excellent. I use them in the ZeeBooth Blink cameras. They don't last as long as I thought they would. Perhaps 3 to 4 weeks at most in my most active cameras. Charge time is about 4-5 hours for 8 batteries on the charger at the same time. Its a RECOMMEND if you have easy access to whatever you are using them in in order to swap them out.

September 2022 Update: Bottom line? These are lithium AA batteries done right! I have a battery toothbrush, and alkalines don't seem to last very long. NiMH rechargeables don't seem to put out the voltage to make the toothbrush work very well. These rechargeable lithium batteries are PERFECT for the job. They put out strong voltage, and so far they are running my toothbrush, flashlights, and whatever other device I use them in MUCH better than NiMH batteries. These are great for devices where having the full 1.5v matters. Also, I have one other brand of lithium AA batteries. They also put out strong voltage, but they also have circuitry for lighting when they are charging. While this is a neat effect, like the lithium AAs with built in USB ports, any additional circuitry takes up space that could be used for actual battery capacity. These EBLs last significantly longer than the other brands of lithium batteries I have. I highly recommend them. You're getting a pure battery that will last as long as possible with no superfluous bells or whistles. And that's how I like my batteries! Excellent product by EBL. May 2022 Update: EBL has AWESOME customer service. I'm updating my review because they replaced the batteries with a new set, and the new set charges PERFECTLY! I must have just had a bad batch, but I'm happy to report that EBL stands behind their warranty on their product. If I have any additional issues with the new batteries, I'll update, but so far so good!! Old review: So first off, my son ended up taking them. He planned on using them but never did. Never used them and never charged them. Since we purchased these batteries we have had to move. As we've gradually been unpacking, we finally found the batteries. They all look brand new and have no signs of use. They are over a year old, but as they've never been used or charged, I never expected them to be bad! Sadly, 6 of the 8 batteries won't charge. The 2 that do don't hold a charge very well. These were expensive, and it was a lot of money wasted. As you can see in the picture, six of the batteries don't charge at all. They will stay red indefinitely, even if the charger is connected for several days! I have other lithium AA chargers, and those charges also do not charge these EBL batteries. My older lithium AA and AAA batteries all work fine. These EBLs are the first ones I've ever had problems with. Moral of the story? Make sure you test your studf out RIGHT AWAY before your return policy runs out.
