Maybe you should switch to those pre-charged NiMH rechargeables.
They hold their charge much better than ordinary NiMH cells.
Then you can recharge them every so often and not buy so many alkaline
cells.

Rechargeable batteries are not a good choice for his keyboard
because it uses three cells. If he leaves the rechargeable cells in
the keyboard until it no longer works, one of the three cells will
be reversed and ruined most of the time.

Some devices are designed to use rechargeable cells. They shut off
when the voltage drops to around 1.0 to 1.1 volts per cell. Devices
that use just one or two cells can not reverse cells.

They were all gourmands!
