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

Excellent battery Why did you pick this product vs others?:The reason why I pick this product is was bought in the pass but directly to Ebl web site thank you guys Charge speed:Charge fast as well .

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 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.

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.

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.

You will not find a better more reliable battery.

Well 7 of the 8 batters work great but 1 was dead on arrival. My meter shows zero volts (the others were all over 1.5 as normal). I tried recharging it but my charger gives it an error after running its diagnostics. 2 of the 7 good ones charged well.1 battery away from 5 starts. : (

They work, but don't hold a charge very long in our Blink cameras. And with each subsequent use, the charge's duration is getting shorter. After cycling about 10 times, down to two or three days in a Blink camea.
