Coin cell recharger?

anon_ymous

There's a decent amount of chargers and rechargeable batteries when it comes to AA and AAA batteries but I'm looking at rechargeable CR1632 batteries and a corresponding charger, I don't find much

Does anyone know if such a thing even exists? Or are they kinda like those alkaline chargers where they technically exist but it's basically pointless because the amount of charge continually decreases at a rapid rate?

Well, there's this. Don't know how reliable it would be, it has non-uk mains pins on the back, but there's a USB input too by the look of it.

Theres also this which is just one cell and just usb input.

Both not much more than a fiver.

Genuinely rechargeable button cells are a thing, most desktop computers have them for clock backup. No idea how long these kinds of chargers would take to recharge a drained cell, I'd assume from the price they're just simple trickle chargers and it would take a while, but these cells are typically used in places where they take a long time to run down as well, so I can't imagine it's much of a bother.
