EEMB 10PCS LIR2032 Rechargeable Battery 3.7V Lithium-ion Coin Button Cell Batteries 45mAh 2032 Rechargeable Battery

OMG the wonderful world of LIR rechargeable coin cell batteries For the longest time CR style coin cells were the only reason i said i couldn't go full rechargeable. With 10 Apple Air Tags and 20 smart home sensors all running on CR 2032 and CR2450 batteries, i was buying in bulk. I recently swapped all my AirTags and Sensors to LIRs, have not noticed any performance issues and am just now needing to recharge my most Frequently used ones three months later. Far more sustainable. I am not going back to traditional CR Cells.

I had fully charged these and put them in a battery storage unit in a drawer. I went to get one to use in a security device. Upon replacing the old one, within 15 minutes, I was alerted that the battery was dead. It's a rechargeable unit, so I attempted to charge it, and it needed a charge. I also went to use a different one, and two others were simply overheating and were just sitting in the storage unit.

This is a great value for the batteries. at 45Mah they will not last as long as their alkaline counterparts. However I have NEVER know a single rechargeable battery to last longer than their alkaline counterparts. The point isn't to be better, the point id not to have to buy new batteries often. Yes you have to charge them, but that's better than buying new ones and throwing the old ones away.

Siento que la carga le dura muy poco, donde una de estas alcalina me resiste 2 meses, estas a penas me soportan 2 semanas

Sometimes the items I order never arrive. Or gets canceled and I never get refund for them. But usually I get everything ok. I use these items for my electronic design and reach.

I was buying coin batteries by the truck load. And could never buy any with a full charge till now. With these Lithium-ion rechargeable replacement coin batteries anytime they start losing charge. I just recharge them & upto around 300 times each. Math whiz or not these are a great deal. And a great deal even if some say they don't work well in everything. When the truth is with a little preparation & forethought there's few situations these won't work well in.

Poor quality. Discharges fast.

The charge doesn't last very long. I put them in some timer tealights. After about an hour, they start fading and are dead within 3 hours.

古いポケコンでCR2032の代わりに使ってます。 ホントはCR2032が3V、コイツは3.7Vだからあんまりよくないのではありますが、こちらを使うと液晶のコントラストがハッキリします。 しかも一度満充電するとかなり長持ちします。中華製の充電器で充電してますが、問題なく使えてます。 そういえば結構使っててもなかなか電池切れにならないですねぇ。以外とタフです。

充電しても直ぐ使えなくなって使えませんでした。

10個入りを2セット購入しましたが4個しか充電できなかった。

一般的なコイン型リチュームイオン電池は3Vですが こちらは公称電圧3.7V充電終止電圧4.2Vも有ります 使用機器に使えるか事前に確認が必要です

問題無く使えています。
