Lithium Ion 2032 Battery Charger for Coin Cell Rechargeable Batteries LIR2032 4pcs Replace CR2032 Batteries

Who knew they had rechargeable 2032 batteries - I didn't.But, I did find this and have since use and recharged these batteries several times.Very handy.I use a heart rate monitor that goes through the 2032 batteries. I have always put off changing the battery until it actually starts giving me problems. Now with this option, I just change it out so often just to always have a fresh battery in it. They are rechargeable, so no big deal. It has been great.It seems to work good - batteries do recharge and work. I am happy.Hope this helps.

Bought a USB version before i found this one. USB charging is too slow for me, but good for a disaster recovery feature. This one however, is great for recharging MULTIPLE batteries, faster. So if you're like me, and got tired of spending a lot of money for 1 or 2 batteries, then rechargeable is the way to go. So far i like this one best.

Normally I would not make reviews because it is time consuming (or I just forget/am too lazy), but I do like to warn others of some defects.For starters, I thought these batteries would be like some other rechargeable batteries that would be reliable. Unfortunately, these are not it. I will say, the recharge station does work. Now onto why I have a 1 star review:- The batteries do not last long at all. Maybe 4 hours at best even after a full charge. (Mind you, this is after purchasing these for less than a week of this post.)- The packaging in which I received this was atrocious. Not only were the batteries outside of its sockets within the package, it was also poorly taped together- The packaging, after removing the dense job of taping it together, contained food stains. I thought this was strange.- Lastly, one of the barriers is defective and will not recharge.Now, let me start with the good:-Recharge station works. Yup, that’s it.Remember folks: I’ve had this for less than a week, as of this post. I would return it, but, as stated earlier, the recharge station does its job. Thank you for taking the time to read.

Batteries don't hold charge very long. Maybe 12hrs.

My key fobs now work on my cars. Having trouble with 3.0VDC CR2032 batteries going dead in less than a month. Turned out the Voltage was 2.8 volts but not high enough for the key fob or the Sonata receiver? ! Either way, two cars and fobs, the dealership couldn't figure it out. Bought some LCR2032's at 4.6 VDC and have been working great. Even 60 - 100 feet away. There is a big difference in voltage and current and, obviously, the signal. Haven't had to recharge them yet.

I guess I should have read the specs... these last about 20% as long as regular non rechargeable...waste of money for me...sorry

This little charger (and the included batteries) work really well. I have some gadgets that voraciously consume CR2032s, and this thing has been a game changer. All the batteries were solid out of the box, and several months later they’re still working very well. The charger is fairly idiot-proof and the micro-usb input makes it super convenient.

I live far out in the country and it is nice to be able to have rechargeable button batteries on hand.
