Tanatare AA Rechargeable Lithium Batteries with Charger, 8 Pack 3000mWh High Capacity 2000 Cycles 1.5V AA Batteries with 2 in 1 Charging-Storage Box

Why did you choose this product over others?:I bought this set of rechargeable batteries to use with my Aqara video doorbell, and I have to say — I’m genuinely impressed!Previously, I struggled with other batteries draining too quickly or not holding a full charge. I decided to give these a try, followed the charging and usage instructions to the bone, and the results have been nothing short of amazing.▶️ After a full charge, the battery level on the Aqara doorbell stays at 100% for at least 5 days, even with regular use and motion notifications.▶️ There’s been no sudden drop-offs, no overheating, and recharging is quick and hassle-free.▶️ The overall performance is far better than any other rechargeable batteries I’ve tried for smart home devices.If you’re using battery-powered gadgets — especially smart home tech — these are 100% worth it. Long life, reliable output, and serious value for money.Highly recommended!

Functionality: I chose these based on their higher voltage. Most rechargeable batteries are only 1.2v which I’d fine for most cases but we use a uv dummy steriliser which requires a higher voltage.Longevity: they lasted approximated twice as long as was expected of disposable.Functionality: They charge quickly in the included case. I did wonder if I’d have to take out the spare fully charged batteries before recharging the used ones but no it quickly indicated that it had completed charging the full ones and continued charging the used ones.Values for money, I would say reasonable, they are expensive but they are a premium product!Fit - they’re no biggest than a standard AA battery

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 USB-C plug (not included) & cable.Once charging, little green lights appear on the top of the unit above the compartments being charged.Having charged these a few times - there charging is very quick and assists solid enough!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 this 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, reasonably priced and appears well built.

UPDATE:I brought these batteries on 7th Jan 25 for my sensors in my weather station. We are now early June and batteries are still going strong i have not charged them apart from when they arrived as per instructions.they have been outside for part of the winter, and spring coming into summer, I am glad I got these batteries as they said they hold the charge in the cold, and they have proved this to me.If you need batteries for out doors i would highly recommend these batteries, that come with their own compact fast charger.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!

I'm really impressed with these! Rechargeable 1.5V batteries are not easy to find and most gadgets that require AA batteries require the full 1.5V. Most rechargeables are 1.2V and leave people thinking that rechargeable batteries are not compatible with their devices. These power our Blink cameras, battery fairy lights, remotes etc. and they last for ages. The batteries come in a neat little case with their own charger. We've saved a fortune using these and also they're more environmentally friendly than burning through disposables.

Charger packed up after 7 months, with little use in that time. No ability to contact supplier. Much more expensive than disposable batteries would have been.

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)

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.
