1.5V AA

Blink states its 2 years life span for lithium batteries... it's a deceiving statement. My lithium batteries died in 1.5 month. These rechargeable batteries are ideal for blink cameras and save $$$ on long run since lithium batteries are not cheap. Would recommend for blink cameras.

Only 2 of the 4 batteries worked even after charging for days. I contacted their support team and they were great and easy to work with. They actually sent me 2 packs of 4 batteries to replace the 2 that didn’t work!

Very poor quality. I had to request a replacement because only two batteries worked, but the second package had the exact same issue. I eventually combined the working batteries from both sets. Returning them seems like a waste of shipping costs, but they have been sent back. I'm now testing the remaining ones. I do not recommend this product

Battery life isn't great, but recharges quickly. But I would buy more than you need sk you can charge some and use some.

Tried these USB-C rechargeable batteries for the first time, and I’m seriously impressed. The built-in fast charging via USB-C means no need to buy extra chargers—just use the cable I already have. Even better, they come with a 4-in-1 charging cable that lets me charge all four batteries at once. I’ve been using them in my RC transmitter, and they’ve held up great through multiple uses. When one had a hiccup, customer service quickly replaced it without any hassle. For the price, the performance, support, and convenience make this a smart buy for anyone watching their budget.

I am using this battery on my keyboard and mouse. I fully charged the battery and its been 4 months and battery is still showing 100%. I have not switched off keyboard and mouse since then

Small things that require their other detachable small parts in order to work right are an issue for this lady who lives with ADD & my ADHD husband lol! These are a man toy…my husband really was captivated by these… Guys like things like this in their Christmas stocking!!! Unfortunately we can’t use these batteries because we have no clue where their special 4 charging at once cord is now… So, * You’ll need to have a rememberable place to store your special charging cord for these… or else; you end up with 4 useless batteries you don’t want to throw away because you know somewhere you have the cord to recharge them. Only you never find that cord and when you finally unalive and your adult kids are going through your things, they’ll wonder why these batteries have those holes in them and probably finally toss them in the trash…

Muy bonito, pero no duran mas de 10 min. En unas luces que llevan 3 baterias doble A. Maybe no sea para ese uso? Pero por ahora nos vamos con 3 estrellas.

They last forever lasted like 1 month in my quest controller before they died

super pratique et intelligent, à voir avec le temps et après beaucoup de recharges, pour l'instant parfait, rien à redire, je recommande réellement, merci

Does exactly what you'd expect. Never run out of batteries again. Really handy for things like battery powered fairy lights, cameras. Come in a really useful case, and the charging cable is excellent.
