Just FYI.

I have several pair, because I thought the batteries were going too quickly.

Turns out, I should have just not left the case on the charger, all the time.

Nowadays, I just let them charge for a couple of hours, every few days, take them off the charger, and leave them in my coin tray.

I haven’t had a single battery issue, since; even on the ones I thought were “dead.”

But I think it’s a big design error, that this happens. Everything else has”smart charging.”
