Tanatare 8-Pack AA Lithium Rechargeable Batteries with 2.5H Fast Charger,1.5V Stable Output 3000mWh High Capacity 2000 Cycles Li-ion Battery with 2 in 1 Charging-Storage Box

I’m really impressed with these Tanatare rechargeable AA lithium batteries! The 3000mWh capacity provides consistent power, and the 1.5V output remains steady, making them perfect for my high-drain devices. The included charging-storage box is a brilliant addition, making it easy to keep them organised and charged.The fast charging time (around 2.5 hours) is a huge plus, and I’ve noticed very little self-discharge, meaning they hold power well even when not in use. The build quality feels premium, and they’ve been performing flawlessly so far.Highly recommended for anyone looking for reliable rechargeable AA batteries!

I am very impressed, I’m comparing these batteries and the charger to other li-ion AA batteries and these are so much better. Not only do they have a higher capacity but they are safer too, other batteries have the charging circuit built into them and when connected to a cable then the batteries short each other if they touch and when charging their output voltage is 5V but these batteries do not as they are kept safe inside a case which has additional safety features and can charge multiple batteries safely. I have tried them with my Quest 2 controllers and Logitech mouse and they work like any other battery. I highly recommend these for people who need long lasting, powerful and rechargeable batteries.

Originally purchased this to replace the batteries in my Blink video doorbell artificiality a month ago.Very neat packaging, quality design and looks very premium. Charges easily and fairly well with an appropriately powered mains plug (purchased separately).These batteries do work with the Blink doorbell but you will receive a 'low battery' notification soon afterwards and a low-battery icon on the cameras thumbnail -- it's been like this for weeks and still works well, so it's just a case of waiting until the doorbell no longer rings (aka, "guesswork"). I assume those is more the fault of the Blink doorbell then the batteries as Amazon keeps trying to push Energizer as the implied 'ONLY' replacement.If anything changes I'll update the review - but so far it's reasonably good, recently priced and appears well built.

Arrived promptly all 8 batteries charged within 3 hrs.I brought them for my out door sensors for my weather station.They have been out in -3 overnight temperatures and are still working on their first charge!I was going to buy Nimh batteries but read that lithium batteries are better for outdoor use, I can see I made the right choice here.Charger is also very compact not taking up to much space unlike normal chargers, and it charges all 8 at the same time! Bonus!

We've been using these for a couple of months now and have had no problems with them. The charging case is very convenient and the led inidicators on the top show clearly when the batteries are ready. The slots for the batteries and the magnetic lid makes them much less fiddly than other 'generic' battery chargers, so are less likely to be left not chearging between use. (We use them every Sunday powering radio mic transmitters for 4 hours in a church setting)

Bought these for LED Xmas tree lights. I have to agree with some other reviews. Good. : 1. Bought for the extra power (3000). 2. Recharge unit is compact. Bad : 3. Batteries are unstable. They go from fully charged to dead in minutes. 4. Takes ages to charge. 5. Charger does not recognise other makes of rechargeable batteries. 6. They don’t charge in another battery charger. For me it was a waste of money.

Works well with easy to read indicators for state of charge. Occasional use so I can comment on performance or longevity.

Very good value set of 8 rechargeable batteries +charger. Very neat design
