1.5V Rechargeable AA Lithium Batteries 8 Pack, 3600mWh Lithium Rechargeable Long-Lasting Double A Li-ion Batteries for Blink Outdoor Camera

Edit: The seller contacted me and painlessly made things right. Props.They seemed to work fine, but after one discharge cycle 1 of the 8 cells is dead. Voltage reading is 0 and it will not recharge. The other 7 are fine… for now. Not confidence inspiring.

Don't know yet...they were delivered to the air freight company yesterday I think, but I won't see them for another week as we only get mail out here once a week. But I've had these batteries before and they work great in my handheld radios, so you got that going for ya.

Excellent 1.5V Rechargeable AA Batteries at reasonable price1.5V Rechargeable AA Lithium Batteries is the best economic and environment friendly alternative for alkaline AA batteries. It is especially useful for the devices and applications that need an operating voltage higher than 1.2 volts as Ni-Mh rechargeable batteries cannot be used.The problem I previously have for such Lithium AA batteries was that their marked capacities are usually greatly exaggerated. As an example, one set of the batteries that I have was marked as 5500 mWh but was actually only 1500mAh or 2250 mWh. This made buying decision difficult. Moreover, 1500 mAh is also less than the capacity of regular alkaline AA batteries.Recently after I made another unsatisfactory purchase of another brand of such batteries, I decided to give these Dracutum AA 3600 mWh Lithium Batteries a try. To my (pleasant) surprise, they worked very well. Their capacities at 1.5 Volts are between 2100 to 2200 mAh. Then the voltage reduced to about 1.1 volts that lasted a little bit longer. The total capacity is about 2200 to 2300 mAh. It is still a little lower than the claimed capacity of 2400mAh/3600mWh, but I feel this is acceptable. The discharging curve of one of these batteries is attached.The price of these batteries is also reasonable. With discount coupon on Amazon, 8 of such AA batteries cost less than $18. Comparing to the best of such batteries reviewed and published online, such as Hixon and Xtar, their capacities are almost the same at about half of the price.For now, I am very confident to recommend these Dracutum 1.5V 3600mAh AA Rechargeable Lithium Batteries. I will update this review after using these batteries for longer time when I have new information.Update: Unfortunately, after a couple of charges, one of the batteries stopped working. It didn't hold charge anymore and cannot be recharged in anymore. I hope all the other batteries can be recharged up to the times as promissed.

I have a lot of trail cameras and I thought these batteries would be a good option so that I would not be continuously changing batteries. However, for Lithium-ion batteries these things do not have the life they should have. Likewise many times I have to insert the battery into the charger many times to get a green light because it thinks the batteries are defective.UPDATE: after using these batteries since April I am barely getting two weeks of use in a trail cam. Likewise the spare set that I have has a high rate of self discharge which should not be the case with a lithium battery.

These are strong batteries with extended life. Charging with the dedicated charger is very fast. I recommend

Update - Changing from 1 star to 3 stars since the seller reached out to me and offered a refund. Great customer service!Bought these batteries to use in my smart lock and they died within 3 months. Tried charging them but they would no longer hold a charge. Would not recommend.

Good guality ,fair price.

Use these 8 AA in all my tools daily, so far have held up well and work great in the single AA tools. Charging time is pretty decent so I wait till they won't power on anything then charge up and pull off the charger so nothing cooks. I did test one in a yard light in the dark of my garage last 3 days on solid.
