Deleepow 4 Bay AA AAA Battery Charger, LCD Display, USB High-Speed Charging, Independent Slot Only for Deleepow Rechargeable Lithium Batteries

The batteries work well. I have a charger and it doesn't work on it. It works with all the other batteries. Deep low has to use their own battery charger.

May not last as long as Alkalines but don't have to deal with recycling batteries and buying new ones.

I've used EBL rechargeable lithium AA batteries from day one of installing my Blink security cameras. I bought this brand for the first time because of a discounted sale. I immediately noticed several bad things happen to my camera system. The live view feature would not activate, the sensitivity would not trigger, night vision was completely shut down, and when I contacted Blink support, they advised that all these things happen when the batteries are too weak. They claimed that this typically happens when customers try to be "economical" and use alkaline batteries instead of the required lithium batteries. In other words, they were suggesting that these batteries were performing no better than alkaline batteries. VERY disappointed.UPDATE AS OF 08/15/2021. After seeing this review, the seller contacted me to point out that, in fact, there was a note on the item description page that stated that these batteries were not compatible with the BLINK cameras. The seller was gracious enough to offer me a refund, even though I had exceeded the time limitation to return the item. This was really helpful and I am impressed by the proactive customer service. I almost always post a review, be it a restaurant, a car repair shop, or a purchase -- major or small. I'm glad this had a happy ending!

I have had 2 cells die prematurely. One did not take a second charge after prematurely losing charge (compared to the rest of 8 in a battery pack). The second one took maybe another 2 charges before it could not take an additional charge.Now after 15 months of owning these cells, I have had another one die after 4 charges. I have a volt meter so I know it dead as there is 0 amps that I can draw. There are 3 more of the 8 cells I have had from the beginning that are showing signs of charging difficulty.The thing is, these are being used in cordless window roller shades mounted high up on a stair case. It is extremely difficult to go up and retrieve the pack to charge the batteries. I have a total of 3 windows with packs of 8 cells. So, really hate it that I have to make that climb up on the banister, as it is not easy to set up a ladder on the stairs. I hope that the seller compensates me.

There are many rechargeable batteries on Amazon, but many are out of stock. I use Amazon’s alkaline batteries, but I wanted some rechargeable AAs. I found these because they were in stock, and I am glad I picked them!These are rated 3200mWh vs. Amazon’s rechargeable AAs at 2000mWh. What will that do for you? Well, they will last longer. Every year, Apple gives presentations on how they are able to get longer-lasting batteries and larger capacities. Capacity is rated in milliwatt-hours (mWh). The larger the number within the same battery class, ie. AA, AAA, C, D, the longer your devices should run. These should be roughly 60% longer lasting than Amazon’s batteries. Obviously it depends on the device and how much it pulls, but usually, this is how it works.I really enjoy the USB interface, I wish it was USB-C, but this will do. I have so many USB devices, this is helpful since I do not have to worry about losing another bulky power adapter. You should enjoy this as well.They charged in less than two hours. The higher the mWh, the longer it should take to charge.The self-discharge isn’t bad. These AAs will retain upwards of 80% battery life after 12 months. Basically that means, if you charge these and don’t use them for 12 months, they should still have more battery life than a fully charged Amazon AA.There are SOOO many devices that need these, I am just happy I was able to find some that worked for me! I hope they work for you too!

Bought 12 of these batteries and two chargers because I needed them for usage in trail cameras that use 6 each. After about a week, each camera showed low battery. When I check the voltage in each of the 12 batteries, I found 2 that were completely discharged. Charged them and reinserted. A couple of days later checked all the batteries and the same two had lost their charge. The other 10 are great and have an initial charge of 1.54v to 1.56v. Should have contacted Amazon or Delipow but just didn't get around it till it was too late.

If I was designing and selling this product I would make sure they were actually the same size as standard AA batteries. Not much good to anyone if the batteries don't fit. Slightly larger diameter becaiae of label. You can't remove said lable either because it holds the positive post on. Also that post is just a bit shorter than alkaline batteries so it doesn't quite reach in some scenarios.

9v batteries have been relegated to antiquated electronics as AAs rise in popularity and built-in rechargeable batteries become the new norm. However regardless of the trend, there's always going to be some electronics that work perfectly fine with the older style batteries. If you don't need to replace it, why bother? I'm glad these "retrofits" exist. I can't be bothered to spend $3-4 for a single 9v one-time-use disposable batteries. Even though it lasts a while, I find it unnecessary. Moving into the 21st century, we can now buy rechargeable 9v batteries that simply require micro USB to rechargeable. Better for the environment and simply more convenient.These batteries work exactly as promised. The battery charge measures at 9v and seems to last a while. The charge is quick and the capacity is large. No problems so far. The convenience of the micro USB port means I don't have to worry about getting a separate charger for something I don't use often. The size is identical to my disposable 9v battery. The LED indicator makes it easy to tell when it's charging and when it's full. Glad to get something like this for a good price. Hard to beat Li-Ion cell density.

Have switched over to lithium to operate remote blinds. These work much better than NiMh batteries. Am pleased with my purchase.

These batteries are not 1.5 Volt as advertised. They charge to 1.3 Volt max and are dead at 55% Wrote to both the Seller & Manufacturer a week ago and both have ignored my questions. Very Unhappy as batteries are very poor quality & NOT as advertised.
