EBL Lithium AA Batteries 4 Pack, Rechargeable Double A Battery 1.5V 3500mWh with USB-C Cable, 2H Fast Charge, Over 1600 Cycles

Update: 3-15-25 I didn't notice customer service had contacted me twice after my review so this update would've been sooner had I responded. Once I did, there was no typical back and forth that is often the case when dealing with customer service depts. I only typed two words and they sent a replacement without wasting my time. This is how customer service should be and they deserve their own 5/5. Ordering batteries online can be risky and it's not easy to send them back so it's nice to know I can buy EBL with confidence at an affordable price. That said, I'm going to offer to pay EBL or if it was the seller for the replacements. The dents and the uneven button top wasn't wear from my controller which is good because it means they're not falling apart or too big. The dents at the top is on them all and simply how its manufactured. The uneven button isn't considered a defect by any manufacturer or by any standards, verified using Bing and Google's AI to find legitimate information. I just thought it looked crushed in from being in the controller but I'm glad I was wrong. I might have not said anything about it and just kept the replacements but the fact is I'm nowhere near the return window and they didn't have to reach out to me at all. The least I can do is admit I was wrong and pay for what I got.With that out of the way, you're reading reviews trying to find a good battery that don't cost a fortune, right? EBL checked all of my boxes and I can vouch for these lithium AAs and their Ni-MH AAAs. My quest 3 controllers were burning through my enloopes and thankfully, these lithium AAs can handle the power hungry Touch plus controller. All I hoped for was to reduce changing them as much and that's what I got. I can never go back to the Ni-MH enloopes I was using. To give you an idea of the difference, I used the EBL in the right handed controller that I use the most as the pointer. I put the enloope in the left controller so the disadvantage would be on the EBL because it is lithium after all. Even so, I went through about 2.5 eneloop charges before changing the EBL and considering the advantage eneloop had, I think that's great and I know this is a bad way to compare batteries, but I'm really just comparing how often I have to change the batteries, not lithium vs Ni-MH. I don't care what they are, I just don't want my game to be interrupted as much. If that's what you want, then give these a try, and I think you'll be as happy as I am. I also tried EBL16ct Ni-MH AAA w/charger that's turning out to be a solid purchase as well. I'll review them next.I don't expect to get eneloop's longevity out of these batteries and that's okay because they cost twice as much. Even so, one thing I realized with the AAAs is the more you have the less you charge each one. Since I'm getting like twice as many batteries and charging them less than the AAA eneloops that I charged twice as often, then in the end I'm not sure how it might turn out. If you thought I was going somewhere with that, so did I but now I'm not sure. I'll just have to wait and see. I'll update in a couple years or earlier if something goes wrong. If you're reading this two years from now, you're in luck! Otherwise, just order your batteries and move on. I spent way too much time on batteries when I should've been playing my quest. EBLs are great and if something goes wrong they'll fix it. What more can you ask for?OG review:The good: I use these for the meta quest 3 controllers so I can only compare them with AA Enloope. I know it's apples and oranges but all I know is I change out the batteries way less now which is what I was hoping for.The ugly: All was well until I removed the battery after using it for the first time. It took a beating close to a 1st round KO with visible wear to the body and an uneven button top. That's after one use! I checked the Enloopes that I've been using since the quest 2 and not a scratch on them. The build quality is poor but who knows, maybe they will still last a while. I'll update after I find out. For now, can't recommend.

Cansado de estar comprando baterías desde que compré estas a mí en lo personal me han resultado muy buenas las he cargado muchas veces y aún sigues manteniendo toda la carga si necesito más en un futuro compraré por el momento estoy muy contento con estos

This four pack of rechargeable lithium ion AA batteries is as you would expect. They come with a charging cable that splits into four so all can be charged at the same time. I do find that plugging a USB cable in can be difficult. There's an integrated light to let you know the charging status. They can be charged with any other USB-C cable as well.

The batteries and the charging cable are well-made. I have only charged the battery once so far before its first use. The charging indicator is really helpful, and it did not take too long. The batteries work well for the device, which was not happy with 1.2V from NiMH. One application that did not work out well for me is the milk froster. We were trying to whip up the heavy cream, and it was much stiffer than normal, so we had to run the froster much longer than usual. This extra load on the motor pulls high current for an extended period, causing the battery to shut down. The overheat protection works well in this case. The frost works fine with regular milk. I need to be aware of the Li battery limitation.

Good product. Good price,

In its reviews many people claim they bought this battery because its claimed capacity of 3500 mWh. It sounds pretty good so I ordered one. For a 1.5v battery to provide 3500 mWh, it should have a capacity of 2333 mAh. After receiving the batteries, I did a test of its mAh. The tester shows the first battery test is about 2100 mAh. Its not quite as large as claimed 2333 mAh but not bad. But I noticed that before the test finished, the output voltage reduced less than 1.1volts and lasted for quite some time. Then during testing of the second one, I found when the battery is at about 1.5 volts, its capacity is only about 1500 mAh. Namely, the remaining 600 mAh was generated at the voltage of less than 1.1v. A rough calculation shows its capacity in mWh is only 1500x1.5+600x1.1=2910mWh. However, it you application need a battery of 1.5volts, you can only use its capacity of 2250mWh, i.e., about 2/3 of its claimed capacity.Actually, I'd rather have a battery with 1.5v output all the way with a true capacity of 2900 mWh. What do you think?

they last long

Batteries are very convenient no need to run out to store for batteries in emergency situations.
