My Battery Supplier 5 Loopacell LIR2032 Lithium Rechargeable 3.6V Coin Cell Batteries

Very easy to use

These seem to be working well. They arrived fully charged, with one exception. It is important to note that the stated voltage rating is more than the 3.0v of a non-rechargeable CR2032. Indeed, some measured up to 4.0v, perhaps in a transient moment. I tried using one to light a small LED bulb, and the bulb burnt out. That bulb is one of the free-standing lamps you might put in a panel or decorative device. The forward voltage on different LED's varies, and that can be a clue as to whether a bulb is going to survive. Some colors in my collection work fine with these 3.6v-rated cells, but some were destroyed, apparently by overvoltage. Not the supplier's fault, just something to know.

These were hard to procure and they are Mando so far so good! Need them for car fob, led light remotes, air tags. I can't stand batteries that aren't rechargeable. Plus they always leak and destroy the electronics eventually. Rechargeable batteries never leak and they usually r there for u and many times they can be salvaged for free but not these these r unique and awesome!!

They hold a good charge and provide plenty of power for my AirPods. They fit perfectly in my AirPods case and work just as well as the original batteries.

I'm always nervous when buying rechargeable batteries. This was my first time ordering rechargeable button batteries. I popped them into the charger, and they charged right up. Couldn't be more pleased. I haven't used them as I purchased them for items I use very sporadically so I can't attest to their longevity. That's the ONLY reason I'm giving this four stars instead of five. I don't like when people post a five star review for a product they haven't yet used it its entirety. Those aren't helpful in my opinion.

Good buy good value

I've charged 2 so far and they're 100% so they are a decent rechargeable battery.

These work well for replacing CR2032 batteries in regulated devices (Air Tags, remotes, etc.) but they will blow LEDs due to the high 3.6+ voltage if you try to drive LEDs without a resistor. All of mine arrived half charged and charged up without issue.
