EBL AA Lithium Batteries, 1.5V 3000mWh Rechargeable AA Batteries Long Lasting Double A Battery 8 Pack(Only Compatible 1.5V Devices)

Some time ago, I bought a set of eight of these with the charger. The batteries require a specific charger, so I bought the set first. Those batteries hold their charge well when not in use and they last longer than most other rechargeable batteries I've used.These are also a full 1.5 volt. Many others are 1.2 or 1.3 volt. The 3,000 mWh is also a much greater capacity than most AA batteries. These cost more than many others, but they are worth it.

All arrived on time and well packaged however one of the eight batteries was DOA - totally discharged and will not charge.UPDATE - Seller very promptly replaced the defective battery backing up the product - will go to them again for batteries

I purchased these to use in my trail cameras, as they cost only slightly more than Energizer lithium AA batteries, and the cameras like to eat batteries, especially when it gets colder in late October and November in the U.P. of Michigan. These batteries paid for themselves the first time I swapped them out with freshly charged batteries, which was my goal. These rechargeable have the typical lithium power curve in that they hold their voltage up until the the last day or so, then they drop like a rock, just like normal Li batteries. The biggest difference between these and regular Li batteries is that these charge to 1.5-1.53 volts, whereas regular lithium are typically 1.7+ v out of the package. Depending on the device, that might cause issues as many expect Li batteries to start at a higher voltage. Some devices allow you to pick the battery type, and if that's the case you should select alkaline if it's an option. Speaking of alkaline, these rechargeables work considerably better than standard batteries.These don't hold their charge as long as regular Li batteries, but the fact that they can be recharged obviously negates that a bit. My trail cameras are about 1.5 hours away, but the way things timed out it didn't cause an issue, and I was able to just swap out another fully charged set whenever I was in the area.Now to the reasons why I can't give these 5 stars. As mentioned, the fully charged rate of 1.5ish might cause issues. The second is that not all of the batteries seem to hold their charge at the same rate. I bought 6 packs, so tracking this down to individual batteries is going to be a pain. But right off the charger some seem to discharge quicker just sitting there than others do. Two of the sets I purchased came with the charger. The chargers are pretty cheesy and take quite a while to top off the batteries, and I haven't tried any other chargers. My biggest complaint with the batteries is the fact that there seems to be two versions, as I was sent both. One version has gold colored contacts, and the other doesn't. The version with the gold contacts is physically shorter by about .5+ mm or so (maybe a touch more). That might not sound like a big deal, but when they're stacked in a battery tray, it adds up and the shorter batteries don't put as much pressure on the tray contacts. I have one camera that won't work with any of the gold tipped batteries so I have to pay attention to this. The final thing with these to be aware of is that they are slightly fatter than regular AA batteries. Again, depending on the device, it can make it difficult sliding them into the battery slot. On my cameras, I have to be careful to get them in/out, and I need to pay attention to make sure they're fully inserted and making contact as once installed, they won't slide at all.All-in-all they do the job I wanted them to do. I do need to track down the weaker batteries and get them out of the rotation. It took a while to notice this was an issue so I'm past my return window. I may sound negative on these, but the 4 star rating should tell the story. I just want others to be aware of a few issues. I'm not sure if I'd buy these again, or try another brand. I have a feeling most of them are the same batteries with different wrappers so not sure it will make a difference.

Easy to charge and holds its power. I like it

Worst batteries ever. Ordered one set and out of the first set only four charge up out of the eight when I got the second set only six, which charge up out of the eight contacted. The manufacturer said they would make them good never sent me new ones sent the old ones back got a credit for them. And then they sent me a package and only four charged up.I don’t recommend you buy these spend the extra money and buy a better brand cause even after talking with the company on the phone when they said they would make good and send you new batteries they don’t. That’s what you get for buying stuff from China. The second ones that I bought from another company I have no issues with that all they’ve been running at 100% for four weeks straight And they’re on my Security Camera cameras.These don’t work don’t buy them

The media could not be loaded. I love these batteries! I own maybe $200-$300 worth of these batteries. I have stopped buying disposable batteries once I became aware of the lithium ion batteries in the AA and AAA size. I use them in kids toys, thermostats, flash lights, outdoor thermometers, indoor air quality monitors, walkie talkies and etc... I no longer worry about burning through disposable AA and AAA batteries. I have most likely already achieved a full ROI on these batteries. These batteries hold their charge as well. For example, you can charge them and then let them sit on the shelf for months without loosing a charge. As far as fit, they do seem to be a little bulkier then a standard AA or AAA battery. However, I have never had an issue getting them into a battery compartment on a device.

Probably not what most people think of as the primary application for these.... but I find these most useful with my Schlage Encode smart locks. The Schlage is meant to be used with alkaline batteries and so if you try to use Nimh rechargeable batteries with them you will find it is constantly alarming for low battery. These lithium cells have a nice flat voltage curve and last a very long time in the smart locks. A bit pricey for such a specific application but trouble saved nonetheless. The only slight downside with using these is with the flat voltage curve the Schlage will always think it is at near 100%, so it will basically just work until it doesn't.Out of the 16 I have over the last 2 years, one has died so far and would just not hold a charge any longer.
