EEMB 4-Pack 1.5V AA Lithium Rechargeable Batteries with USB-C Fast Charging Cable - High Energy 1000+ Cycles Compatible with Toys, Flashlights, Remotes & More

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!

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.

Junk don't buy. I have tried four times to charge these batteries. They will not take a charge. Unfortunately I had recycled the box so I can't return them.

Bought 2 sets. 6 0ut of 8 batteries charged 2 didn't. Tried multiple times. I'm ok because I only needed 2

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…

Overall, this product is worth the money if you’re using the batteries for other purposes. But this product clearly states it can be used in the blink doorbell system although these batteries do the exact same thing that regular batteries do and the blink doorbell. They only last two days before you have to replace them. This was the only reason I purchased these batteries because it clearly states they can be used in the doorbell. Would be returning them if I didn’t need them for other stuff.

Hasta el dia de hoy es de perfecto funcionamiento muy buena calidad
