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)?
I think most of my machines which have batteries just use them for things
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.
(I don't suppose anyone is working on a big list of machines with
batteries in,
which ones need consideration before removal, and which ones
refuse to function without a battery present, are they?)
cheers

In the early days of amateur radio transmitters with embedded microprocessors, some idiot
manufacturers put the firmware (all of it) in battery backed RAM. So if the battery went
dead, you had a boat anchor, not a radio.
I hope that sort of thing isn't what you're dealing with here...

I'd also very much like to know this too. I have three of these things and would like
not to lose them to a battery leak. I have done zero investigation so far apart from
taking a look and not seeing a visible battery problem. But I was hoping to do a battery
sweep later this summer, and these were among the ones I wanted to seriously look at
de-batterying. Anyone here successfully replaced the battery? I honestly haven't
checked the manuals to see if there are any notes on this, there might be. I think I have
the SAMS pamphlet on the QX-10 as well, which might say. I'll look around and report
back if I see anything relevant.

Hi Paul,
As I mentioned, I did try a standard Lithium battery after disabling the
recharging circuit. The machine just would not fire up boot. I haven't
tried a NiMH or Lithium ion rechargeable though. I'd be interested to know
if these work.

take it to the dealer to have the battery replaced when it is getting low and losing track
of the time (so they can back up the CMOS RAM for you). There did not seem to be any dire
warnings about crucial parameters or firmware being lost, and there was another section
that indicated that the battery should be disconnected when taking part of it apart, so it
seems like it shouldn't have unrecoverable consequences. But it is distressing that
you're not able to get yours to start again! I'm hoping that someone here will
know a secret that we don't yet know.

No, that's not the case fortunately. It would only not start with the new
battery and the recharging circuit disabled. I soldered the old battery
back in and reconfiguring the charging circuit back to what it was. It
works fine now. It's just (1) the battery is old and I'm worried about it
leaking at some stage and (2) I'd rather have something in there that is
not rechargeable. I don't use the machine often enough for the battery to
remain charged (especially a battery as old as this one) and I have to
re-enter the CMOS parameters each time I drag it out. (:
Cheers
