Artman Rechargeable Lithium AA Batteries 8-Pack 3600mWh with Fast Charger, AA Lithium Batteries for Blink Outdoor Camera, 1.5V Constant Output Double A Battery Recharge up to 2000+ Cycles

I have loads of Blink cameras around my house for different things and was tired of going through expensive lithium batteries like water. Bought these as they were well rated and lithium. They work great in the Blink cameras and everything else I have used them in. My only complaint is the way the usb cable plugs in to the lid of the charger. I have had no issues with dead batteries from this brand. I have had a few that when used in the Blink they show as low battery but work nonetheless.

Bought these batteries for our blink outdoor cameras as the disposable replacement batteries prices have gone up so much we were looking for another option. Batteries arrived and I charged them and when the old disposables die, I've been replacing them. Had one camera stop responding all of a sudden, went and swapped the batteries out and went to recharge the new ones I had removed from the camera and one battery wouldn't charge, the charger showed all the other batteries were charged with a steady green light, but this one was flashing red. I swapped it to another charging bay and tried again with the same result. Emailed the seller and explained the issue, received a prompt response with an offer for a total replacement of the charger and all 8 batteries free of charge. I was hoping for a replacement battery. Problem resolved in just a couple of emails. So far the one battery is the only issue I have encountered and the customer service was fast and resolved more than my one battery issue. Can't recommend this seller enough.

Added: For those using these for Blink cameras, the problem is not with these batteries, but Blink expects Lithium batteries that have a nominal voltage of 1.7V, not the 1.5V that Alkalines have and the Artman's mimic. So, to a Blink camera a 1.5V battery looks like it's going empty. Using Alkalines in a Blink will also immediately result in an empty battery indication. They work well. Easy charging. Claimed capacity is 3600 mWh, which btw is only 3600 mWh / 1.5 V = 2400 mAh => I got missed that when researching, since most battery manufacturers claim mAh. Measurements, @ 100mA discharge, give 2700 - 3000 mAh (1800 mAh - 2000 mAh). Big disadvantage of course is sudden death (very steep slope when getting empty), so no low battery warning from your device. But that is inherent to the technology used. Although they could probably add something in the electronics to mitigate this.

Great product for recharging AA batteries. I use this to swap all my Blink outdoor camera batteries. There are LED indicators on the top of the charging case that show you when the batteries are fully charged. Long lasting batteries

If you have a Blink security system, you have to buy this product, otherwise the cost of replacing the lithium batteries for all of your devices will bankrupt you. Well constructed, the price is reasonable, easy to use, and convenient to have on hand.

I was initially pleased with the price on this lightning deal. I wanted a good solution of rechargeable lithium batteries for my Blink cameras. I started using them and they lasted a good amount of time. However, the first time I recharged the set, they indicated a fault and would not recharge. I bought 2 units, and the same happened on a set of batteries in the second set. Unfortunately I didn't even use them until after the return window had closed. I'll continue using the other good ones little by little until they die I guess. They do take a while to recharge though, but I do like the compact easy to use case.

Bought the 8 pack at the end of February. Used in a game camera. Worked fine until I tried to recharge them. Seven of the 8 recharge just fine, but the 8th will not recharge. Warranty period is only 30 days - which equates to, in my mind, no warranty. Find another brand!

I bought 2 of these. They came charged, they charge fast and I find them to be very good.
