EBLAA Lithium Batteries, 1.5V 3000mWh Rechargeable AA Batteries Long Lasting Double A Battery 8 Pack

Swapped these into my trail cams and they have gone 3 weeks now without needing a charge. With the previous rechargeable NiMH batteries I had to charge every 3 weeks. With a small solar panel on each cam these Li-ion batteries appear to be maintaining 100%.

I have these in my trail cameras with solar panels attached. Once I got the solar panels pointed in the correct direction to collect enough sun, I have not had to recharge them in over six months. They are a reliable battery. You cannot just use any battery in a trail camera because they will drain quickly. These charge up and hold a charge. This is way more cost effective to use these than buying disposable batteries. I had one set that got moisture damage, and I only lost one battery out of eight. I was doing 3-minute videos which seemed to drain the batteries, so I have since only been doing 1-minute videos which these batteries seem to have enough power to do and still keep a full charge.

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.

Bought these to use in my blink cameras. I have a bunch of them on the farm and due to them being in high traffic areas it’s not cost effective to use non-rechargeable lithium batteries. These work great and are still going strong.

This is my 3rd purchase of this brand of batteries.I've used the other 2 sets of 8 in trail cams. They do not last as long as a lithium battery pack which makes no sense. I've changed\charged the batteries about a dozen times now and one set has 2 batteries that complete the charge an hour before the other 6. The other set takes about 2 hours longer to charge.With this specific purchase, the batteries arrived dead. I was not able to locate an expiration date. It took about 3-4 hours to charge them. They must have been sitting on a shelf for a decade to have arrived dead when the batteries say they are pre-charged and ready to be used on them.When you have 8 batteries in one device and suddenly 2 of them charge more quickly than the others it means either 2 or the other 6 batteries are going bad because they should all be depleted together and charge to full together. Having one set take 1-2 hours longer to charge is also not a good sign. It could be the charger, but I marked it so that I will know next week when I charge the two sets again if one charger is taking longer than the other. Both chargers are the same correct model for these batteries.

Me encantó, tal cual la foto, buena calidad, entrega rápida

It stays fully charged until the end. Perfect replacement!

Soon after I got these, a few stopped working and refused to charge. Considering how much these cost and quality control issue, I wouldn't recommend this brand except on sale. Try a different brand or stick with disposable alkaline.These Lithium based batteries do output true 1.5v similar to disposable alkaline batteries which is great for some electronics that can't run off 1.2v that NiMH based batteries output.
