4 Pack AA Lithium Rechargeable Batteries, 3700mWh High Capacity, 1.5V Constant Output, 1600+ Cycles, for Blink Outdoor Camera

These rechargeable AA lithium batteries work great, especially for devices that need stable power like security cameras. The 1.5V constant output keeps the performance consistent, and I noticed my devices run smoothly without sudden drops in power. The high capacity is impressive, and the batteries last a long time between charges. I also like that they can be recharged many times, which saves money compared to constantly buying disposable batteries. The 12-slot charger is very convenient. It allows charging all batteries at once, and the setup is simple and easy to use. Everything feels well made and reliable. Overall, this is a great rechargeable battery set for home devices, cameras, remotes, and other electronics. Highly recommend if you want a long-lasting and cost-effective battery solution.

I am extremely happy with these Rechargeable AA Lithium Batteries with Charger. I’ve tried many rechargeable batteries before and these are by far some of the best I’ve used. They hold a strong charge, last a long time in high-drain devices, and recharge much faster than traditional rechargeable batteries. The charger is very easy to use and the indicator lights/display make it simple to know when the batteries are fully charged. I’ve been using these in things like wireless mouse, keyboard, remote controls, and small electronics, and they work perfectly. It’s great not having to constantly buy disposable batteries anymore, which saves money over time and is also better for the environment. The batteries seem very well made and reliable, and I haven’t had any issues with charging or performance. Everything works exactly as described. Overall, this is a high-quality product and I would definitely purchase again. Highly recommend these rechargeable AA lithium batteries and charger to anyone looking for long-lasting, reliable rechargeable batteries.

I'm very happy with these batteries. They maintain a constant 1.5V output, making my devices last longer and perform better than with other rechargeables. The included charger is super easy to use and feels very high-quality, charging all the batteries at once. The perfect solution for my high-drain devices. Highly recommended.

I got these about two weeks ago specifically for my Blink cameras and they've been great so far. The 1.5V constant output is a real advantage over regular rechargeables that start dropping voltage early on — my cameras haven't complained once. The 12-slot charger is a nice touch since you can do all 12 at once, which is exactly what I needed. Charging time seems reasonable, around 3-4 hours for a full charge. Haven't had any issues with heat or anything unusual during charging. For the price and the capacity (3700mWh), this is a solid deal. Already went through one full cycle and performance held up well.

I'm extremely disappointed in these batteries as they had great reviews and I purchased them trusting in what others had wrote. They were worth a try but hopefully I can find something better. They don't take terribly long to charge and initially they started to work fine held a charge for a month to 6 weeks. Like some other reviewers I bought them to use in outdoor blink cameras. I don't have the settings in the cameras set for high sound or motion detection to avoid draining the batteries. I also live in a low traffic area. It's a quiet neighborhood and maybe a couple deer set them off a few times a day so I am boggled at how these die so fast. They don't last more than a week (some a few days) which is ridiculous to be changing them that frequently. I understand they are outdoors but it hasn't even reached below freezing here in the NE yet and I've only had them a couple months, charged several times and they're deteriorating rapidly. Update: 1/12/25- 2 stars to 4 stars* The seller has rectified the above issue. They were very responsive, friendly and prompt. They went above and beyond. It's evident they care a great deal about their product quality and customer satisfaction. Since, I've purchased 2 additional smaller sets of these batteries/chargers and have not encountered any issues with charging times or longevity. They have performed and held up exceptionally well. As I mentioned it gets cold the NE, and now these have been outdoors 24/7 in freezing temps and still work PERFECT! Having the extra batteries charged and ready to go for an easy swap when needed has been great. We also find the AA's come in handy in other things around the house. Having these has undoubtedly saved us a great deal already!--They've saved time, money and a lot of headache. Definitely worth buying!!

Great replacement for disposable batteries. They hold charge well and keep devices running consistently without sudden drop-offs. The charger is easy to use, and having multiple slots is super convenient. Solid option if you use a lot of AA batteries and want something reliable.

Solid rechargeable AA batteries with long lasting, consistent power. Charging is fast, and the independent slots plus clear LED indicators make them easy to use. Great value and a good alternative to disposables.

I have 3 Blink cameras that blow through batteries so I thought this rechargeable setup would save me money. I used 6 right away and was very happy with them. Unfortunately when I needed to change out one of the sets, I realized one of the batteries sitting in the charger never charged. No red or green lights. I tried all of the spots to make sure it was truly the batter and still no luck. Of course I'm past the return window by a week. I don't even want the hassle of returning the whole thing because I like the 7 working batteries I have now and want to keep using them. I'm hoping the company reaches out and sends me 1 new (working) battery. I'll update my review to 5 stars if they do. If you get this far, please verify all 8 charge before using them. I'm not the only one with this issue. Learn from my mistake.
