Can I use other rechargeable batteries?

@ghat no reason why you could not. The keyboard will have the overcharging protection required, since it would use that for the original ML battery as well. BTW the ML 2032 does show some availability and I would try to get one of those first.

"So? is it posible to use LIR2032 instead of ML2032 for the K750? does someone have experience with those?

Thanks!!"
