EEMB 3.7V Rechargeable 2032H Batteries LIR2032H Lithium-ion Coin Cell Button Batteries 70mAh for Car Remote Key Fob Watch - 4PACK

I love these batteries they are excellent for my use. I have a small flashlight that uses them and they come in handy. They hold a charge for a long time and they don't take longer to charge.

Good

these are supposed to last longer than the regular version - we will see!

Fit perfectly and has been working fine.

I have purchased these before. really like them I fee for me the are economical and convenient. I purchased this as a gift for my son several years (Charger and Batteries) ago. So I now have one for myself and the extra batteries.

Well I try to purchase rechargeable batteries where I can and these don't seem to work as expected.The voltage output on the battery is too high for most devices and causes the device to not work. My car remote stopped working when I used the rechargeable, but I put a non-rechargeable in and it works fine. I tested with a multi-meter and verified the voltage was way too high 3.98v - 4.01v for the pack. I'm glad it didn't blow out my car remote as that would have cost close to $500 to fix/replace.The voltage for these should actually be 3.05v - 3.40v why they are making them at 3.7v is beyond me. They should match the tolerances for voltage of a non-rechargeable as that is the international standard IEEE.

Good quality

I got what I ordered and the order arrived on time. These are rechargeable button batteries. I needed one for my weather station which uses a small solar panel during the day and rto power the unit and rrechsrge the button battery. The battery supplies power at night. I won't likely will not know anything about longevity of the product for months unless that rating turns out to be poor. The packaging is actually quite nice. Cardboard backing is sturdy and slides in and out of the hard clear plastic cover, so it's easier to remove a battery than most of the other button battery packs I have used in the past. This leads me to expect that the batteries themselves will also be of high quality.
