Hi Jules

I found removing my QX-10's battery stopped the machines working.  I tried
replacing it with a lithium battery after disabling the recharging circuit
but that didn't work either.

The old battery doesn't show any signs of leaking so I just left it in
there.  I check all my machines with batteries once a year for any battery
leakage so I'm comfortable with leaving it there.

before it leaks (i.e. it's not responsible for storing any parameters which
might be vital to system operation)?

such as TOD clock and so it's no big deal to remove them (and they'll run
happily without), but I do also have various "unknowns" - of which the
QX-10 is one.

batteries in, which ones need consideration before removal, and which ones
refuse to function without a battery present, are they?)
