12 Pack Rechargeable 2032 Battery with Charger, 3.7v LIR2032 Button Battery Can Replace ML2032,CR2032 3v Lithium Batteries for Airtag, Car Remote Key

This is a nice kit to replace the money drainers that I have to use in my alarm system I have to replace the batteries almost every mont (the alarm company says they last up to 6 months) I tried everything they suggested and the result is the same so I decided to get this rechargeable batteries so i can keep my system working all year round plus they can be used in all my cars for the key fob

I thought this would be a great option to use in my flame less votive candles. I want to keep them lit all the time. Fully charged these last less than 8 hours. They don’t even go dim, just lit well and then dead. I had hoped they would last 5-7 days. Big disappointment.

Very disappointed battery do not charge.

The unboxing was horrible. All of the batteries were shipped loose in a ziplok sandwich bag. All of the batteries looked horrible, old, and covered with corrosion - green stuff. First instinct was to return, except I really need them. I am a retired Navy electronics tech, and I have seen worse, but not by much. This could easily be your standard GI stuff of any day. So I plugged in the charger. Only 3 of the 4 slots lit up. Slot 2 was dead. I put a battery in it and it got super hot and smelled of burning in under a minute. Only 2 of the batteries showed a charge of any kind, but amazingly 10 of the 12 batteries charged to 4.0V to 4.6V in roughly 2 hours. All 10 held their charge and worked great in the guitar tuners I bought them for. So two DOA batteries, not too bad actually. So basically I knocked off a star for packaging and appearance, and I took off a star for functionality, which was 80% roughly. Understanding electronics, things work or they don't. For $21 I think this was a great buy, so I am keeping these. A week later all is still very good. I bought 2032 3v Energizers for $4 each locally, and they would not power up the guitar tuners. At an average of 4.4v these batteries did what they were supposed to do. Not sure if I would recommend, and I would NOT buy them again, but....... I am glad I bought these. At $2 a battery, and lets call the charger gratis, a battery set like this is still a steal, in my book anyway.

Great price fast Shipping higher recommend product and seller thank

Qas exactly as described.

1. 1 battery was dead on arrival.2. 3 more batteries only charged a couple times. They are claimed to last 500 charges. So far all have refused to take another charge after only 0 - 5 times.3. I didn't even bother opening the last 2 batteries from the package.4. I was using them in a clip on visor led light side by side with a light using generic CR2032 batteries. These LIR2032 batteries didn't even last an hour. In comparison the light using CR2032 batteries lasted 8 - 9 hours!!! The carbon footprint of these LIR batteries is huge !!5. They were very bright for about 20 min due to higher voltage which potentially shortened the led bulb lifespan. Then they quickly dimmed to be useless.Conclusion: At least for me this purchase was not only a waste of money but an even much greater waste of dollar value of my time; to the point of being unethical for Amazon to sell them!

We have several electronic LED candles in our house, and I wasn't happy using 2032 batteries that ended up in a landfill. This has mostly solved the problem. My one suggestion to the manufacturer is that it would be better if it held more than 4 batteries.
