Can I use other rechargeable batteries?

hi

I understand besides the ML2032 can one use other re-chargeables like VL2032 or LIR2032 ?

VL2032

VL Battery Chemistry

A Lithium Ion chemistry that works well in camcorder and rechargeable electronics applications. Batteries with the VL designation have no memory effect, meaning they can be charged to full capacity at any point in the charge cycle. You don’t need to empty the charge before recharging.

VL Batteries:

Have a high energy capacity

Are perfect for camcorders

Can be recharged at any point in the charge cycle

LIR2032

LIR Battery Chemistry

Unlike the other chemistries, the LIR chemisty has a voltage of 3.6V instead of 3V. This chemistry is rechargeable, however a protective circuit is absolutely necessary due to the very high energy density of this type of cell. LIR2032 batteries are frequently used in car security systems, memory backup batteries in electronic devices, electronic watches, and many other applications.

LIR Batteries:

Have a voltage of 3.6V rather than 3V

Have an extremely high energy density

Are rechargeable, but require a protection circuit

I used them but they stopped working after few days. I don't know why but I tried 2 of them and both failed after a few days. They went open circuit.

@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.
