1.5V AA Rechargeable Lithium Batteries,Kratax 8-Pack Double A Li-ion Batteries with Ultra Fast Lithium AA Battery Charger,3500mWh High Capacity,1600Cycles,Constant Output.[8AA+1Charger]

Bought these for a Trail camera which needs good batteries. It is important to note that you cannot charge these in any Rechargeable battery charger. I tried this with my first set and destroyed all four batteries in seconds. Having replaced them and bought the charger, all was fine. They do last a good time before needing recharging, but like a lot of lithium batteries when they lose charge they basically stop working.The charger has little led lights for each battery to show they are charging./charged (red/green). One of my batteries did not light up when put in the charger and when tested measured 0v, so binned. That was the only one so far, but these have only been in operation a few weeks so longevity a question mark.They are expensive so will need to make a decision whether o stick with them or move to the Panasonic Eneloop Pros.

Work perfect

The reliability of the product is not good. It seems that this was not the first time that all the batteries did not work, see other reviews. I tested the voltage of the non functional battery and it did not even register, while all the others did. The product was returned. Will be staying with Panasonic Eneloop Pro batteries.

These batteries are good I use these on high power appliances such as radiator valves torches and smoke detectors very reliable

UPDATE January 24th 2024 AVOID BUYING THESE BATTERIES FROM AMAZONI bought them in October 2023. They're advertised for use with BLINK security cameras, as they're supposed to be 1.5v. The batteries fully charged would las about 2 days in the blink outdoor cameras. They don't get to 1.5v, they are not long lasting. They're VERY over priced for what they are especially for use inBlink cameras.I requested a return in October of 2023, the same month I bought them. It was a 12 pack. It is now 24th January 2024 and I still don't have a refund from AMAZON. Every time I contact customer service they tell me they need to send it to a specific team. They will contact you in 48 hours. I am yet to have any contact from any team regarding this.I am VERY DISAPPOINTED in AMAZON too, as a prime member I'm pay for this service. I've never had issues like this for returning faulty items.Still now, I've returned items I bought for Christmas presents and they've been returned and refunded without any issues.I can only assume there is an issue with KRATAX and amazon.So PLEASE be aware that THIS is not worth the stress.As for the batteries, the AMAZON basics rechargeable batteries that are 1.2v work so much better than KRATAX brand. The KRATAX are supposed to be 3500mWh AMAZON are 2400mAh the AMAZON ones can last over 3 months in the blink cameras the KRATAX fail after 2 to 3 days. For 12 KRATAX it's £57.99 for 16 AMAZON AA is £17.02 at the time of typingThese batteries are NOT great. They're advertised for being suitable to use in Blink outdoor cameras. So claims to be 1.5v and be long lasting.My mum & dad installed them on 3 cameras outdoor. They lasted 2 days every camera, over a few weeks.The Amazon basics rechargeable are 4 times cheaper than the £51+ for 12 of these.Customer Service wasn't great either.I highly recommend the Amazon Basics rechargeable batteries, even in Blink cameras. They're only 1.2V BUT last for a couple of months easy.

Excellent battery's bought 8 more.

These batteries are perfect for my wildlife camera. After the initial outlay they have saved me an absolute fortune. They are fast charge, longevity is very good. Great compact usb charger. I would recommend.

These batteries are fine but oddly they didn’t work for my cat flap. I had these batteries before some time ago, I wanted some more and reordered them but they will not work in our cat flap. I checked carefully all the numbers to make sure I got the correct ones but they won’t work.
