Rechargeable Lithium AA Batteries with Charger, 3400mWh 1.5V High Capacity, 1500 Cycles, for Household, Cordless Phones, Remote Controls, Electronics (8 Pack)

Exactly as described and works great!!

Every one needs these cost effective batteries, alkalines are such a waste.

These are by far the worst batteries I've bought to date. Delivered the last day of June and already half the batteries are pretty much dead. I use them in game cameras and so far they last a few hours before they shut down which causes the voltage in the camera battery pack to drop and shut down the camera. I also run Deleepow, EBL and Sinceholy lithium batteries which average 3 days of recordings which usually is north of a hundred 1 minute videos. I tried to pair them up with other brands but they still go dead. When I hit them with a current from the charger after they have shut down and they show anything from 0 volts to 1.1 volts. They will show a full charge but then the same problem happens when placed into the battery pack.

I like the charger. Seeing charging rates in the LCD is nice. The AA Lithium batteries charged right up. Some AA Ni-MH batteries I have needed a kick start to get charged. I like the idea of lithium I am really hoping they don't leak and ruin my battery run clocks and other wireless devices. I checked the battery voltages, both types seem to be charged ok. Note the Lithium is 1.5V same as alkaline. Some AAA Lithium I have did not charge from flat which surprised me, my only con was not having both AA and AAA in the package. Otherwise good product so far

8 batteries and the charger at great price! It works as described,

If I could separate the review for the charger and the battery, the charger would score a 5. The batteries a two, as they are just not up to the task.Charger - Operates correctly, charges the cells without any mis-terminations, or any sign of overheating. The charger so far works with other manufacturers such as XTAR and Tennavolts LiON AA cells and charges them correctly. The LCD display provides decent feedback as to the status of the battery being charged. All in all, an acceptable charger. I did not try to charge any NiMh battery in this as I have better chargers for that purpose.Batteries - Nowhere near their advertised capacity. In fact, the capacity of 3,400 mWH could be looked at a deceiving. Battery capacity is rated in Amp hours or Milliamp Hours. So, converting the advertised number to the standard battery rating you get 2,266 mAH, which is respectable for an AA battery. Comparing this cell to an Eneloop NiMh battery, the Eneloops are rated at 1,900 mAH.Putting the cells through the torture test using a Westmountain Radio Computerized Battery Analyzer exposes their serious deficiencies. Not one of the eight cells managed to get even close to 80% of the anticipated capacity of the cell. In fact, most had trouble getting to even 50% of the rated capacity. To be fair, I conducted 16 separate tests, the first round of testing was at 0.4C discharge and the second round was at 0.2C discharge. At 0.4C discharge the cells all failed at or around 38% of rated capacity. At 0.2C discharge all the cells failed at or around 41% of capacity. The delta between 0.4 and 0.2C is very surprising. I would have expected that discharging at half the load should have resulted in double the runtime. It did not.Most people do not put their cells through this type of a torture test, so the last test I ran was a set of these batteries and a set of NiMh Eneloops in a Blink Camera and let the two cameras run until they shut off. I got three days and 10 hours out of the GRBatty and four days and one hour out of the Eneloop.In conclusion, does the batteries work, yes. Do they deliver what is advertised, not even close. Will I not use them, no, I will continue to use them in items that do not play nice with NiMh cells, but certainly will not use them in any high demand item as the runtime will be poor.

Two stars because of Deceptive item description.The first bullet point in the description reads as follows:- "3400mWh AA Rechargeable Lithium Batteries-- 4 packs rechargeable lithium polymer aa batteries with high capacity, long-lasting, ideal for your smart home devices, outdoor surveillance systems, and daily electric devices, such as electric toy, remote controlled toy, wireless mouse or keyboard, bathroom scales, medical devices and so on"The item was purchased in order to use with Blink cameras, which require a lithium battery, and rechargeable seemed like a good investment, especially with the existing discount.The item arrived in good packaging and a manual. The manual is broken down into several sections, with one section named "Battery Usage Knowledge". Number 4 in this section reads as follows: "Most Lithium Rechargeable Batteries can't compatible for Apple Mouse/key board, FM Radio/Blink Camera Series" (this is verbatim from the manual, thus the grammatical errors).This contradicts the item description (outdoor surveillance systems, wireless mouse or keyboard).If you're fine with recharging batteries every 30 days (as per the instructions) and you're fine with NOT using them for certain devices, such as Blink cameras, there's no problem with the item.

I use for my wireless lockes on front and back door. They take 4 each, and this is the second time I charged them since purchased in December 23.They were not dead, I just figured it's been a while, and a dead battery on locked front door is no good, especially when I dont keep keys on me.I give it an a plus, outlasted an Aa lithium non rechargeable and of course the Alkalines.Hope it helps you decide..Chris
