ER14505 3.6V Lithium Battery 2400mAh AA Size Lithium Battery Li-SOCL₂ Non-Rechargeable 4pcs

Please be aware that these are 3.6 volt batteries, more than double the voltage of a standard AA battery (1.5 volts). This is important because if you use them in a device that only requires 1.5 volts, it will very likely overwhelm and damage your electronics.Now that that's out of the way, these batteries are great so far. I use them in my security cameras which require more voltage and they've been going strong for a month now. Lithium is known for its longevity so I expect these to last a while. They came well packaged and worked immediately out of the box. I would recommend these for devices that need 3.6 volts.

I have a couple of weather stations that have remote temp sensors. These remote sensors do not do well with standard alkaline or rechargeable batteries in the colder months. This is where these lithium batteries shine. They can handle the colder Colorado temps much better. I've tried rechargeable lithium AA's and they also work great, but don't last as long between charges as these non-rechargeable lithium batteries.I've never heard of this brand before and the batteries shipped with no branded packaging. So far, so good however, and I'll update this review should I find these batteries don't live up to my expectations.

I got these to try as a cheaper alternative for my Blink Cameras. They seem to work just fine. I don't get a warning about the battery type/life. It'll take 1-2yrs for them to die typically (if they are as good as the name brand). So it's hard to judge longevity within a reasonable time frame. I'll update if these die quickly though. I don't have any reason to believe they will.If these work out and the price doesn't go up, I may get some more.

I needed lithium ion batteries for my blink cameras. I tried these and the camera didn't come on. I check in other devices and the batteries were totally dead. I would not recommend these batteries to anyone.

Pay attention: these batteries are AA sized but deliver 3.6V, more than double the voltage of an alkaline AA battery! Do NOT replace alkaline AA batteries with these, chances are your device will not survive the high voltage.These batteries work as intended, a nominal 3.6V is their voltage without any load. The specs look very good: 2400mah and working temperature range -40°C to 80°. I cannot test these specs, can only tell the one battery I used as replacement for a depleted one does work as expected so far, under normal indoors conditions. The batteries look well made, and they have a 10 years shelf life, long enough to put all of these to good use even though there are not many devices that I have using such batteries.

I used these in a few flash lights and they are great. Lots of power and long lasting, I wanted batteries that would last a long time in my lights and these did a great job,Great quality and preforms well

Long life and low price!

There are still a lot of devices that use removable batteries, old and new. The problem with some of them is that if you don't use them, eventually you lose them. These have a 10 year shelf life so they can go into your emergency kits and (hopefully you won't need to use it) they will still work. Normally you would swap out the batteries every couple years, but these only about a decade.
