My SQ-80 doesn't clack, at least it does not bother me.
And all the aftertouch and velocity works for each key.
call me lucky.

I kept a dying->dead battery in my SQ for 5 years before replacing. I've never heard of one leaking or exploding.

All of those batteries will leak over time -- the only question is how long will they last. I had the same kind of battery in my Poly-800 for literally 31 years (with half of that unprotected in an attic) before I had the entire synth cleaned up. The battery still had 2 volts left it in, but for the $4 it cost to have a new one put in, I wasn't going to risk damaging the mainboard by seeing how much further I could push the battery.

Also, a battery showing only .33V will not save your settings or patches -- or not save them for very long, at least. If you can replace the battery for a few dollars, you might as well. The damage a leaking battery can cause to the mainboard is expensive to repair.

Don't all batteries leak in time?

I'd replace it, power it up, and have some fun.

Has anyone done the ESQ-M conversion to add the extra SQ-80 waves? Is it easy enough to do on your own? I am OK with a soldering iron.

On a different topic.
How many have re-capped the PSUs on your Ensoniq gear?

I have an SQ-80 that is randomly rebooting and I think it is time to re-cap
(once I scope and actually see that the caps aren't doing what they should)

Will be looking for excessive ripple on the +5Vdc line.

It's pretty common to replace the batteries in these with a battery holder that can use standard coin batteries. If you're going to go to the trouble of replacement, you only have to wrangle with it once.

Exactly. And since the Ensoniqs here were newer and more expensive than the Poly-800s (some of which didn't even come with internal batteries), I would hazard a guess that most of the synths we're talking about here have a battery holder that's just waiting patiently for another $4 battery to hold the synth's settings over for another decade or two...and to keep the current one from spilling its guts all over the mainboard.
