The battery of my SAT IV is not holding it's charge. I used to be able to tune 15 - 20 pianos on one charge, but now it's down to 3 or 4. Did I read on this list that someone replaced the battery, but not from Inventronics? Please respond privately or on this list. Thanks.

Hi Wim:  Yes that was me, I had my batteries replaced at the local Bulbs & Batteries store a while back.  They did it in one day and charged me $35.  They are just AA rechargeable batteries soldered in place.

I have replaced the batteries myself in both of my SAT I's.  SAT II is the same.  They are usually the old NiCad batteries, AA size, 4 of them.  You can buy them as a "pack" shrink wrapped together.  It's possible to replace them with lithium rechargeable ones, but you'd have to charge them with a different charger.  The SAT III is not NiCad, I think they're lithium.  I don't know about the SAT IV, but all you'd have to do is unsolder them and take note of any markings on the batteries so you could find replacements.  If you send it in, there may be a substantial wait before you get it back.  Then there's the risk of voiding any warrantee that might still be available.  I guess it might be a good reason to dust off those aural skills!  PM me if you'd like to borrow my SAT III in the meantime.

I have an old SAT II (serial # 19) that's been sitting on the shelf for years.  I like it for very specific things it does well like directly measuring  intervals but it seems to have crashed. I've been thinking about sending it back to Paul but it seems to be a rather expensive proposition.  I've changed the battery in it myself too but I can't remember exactly what I did.  I seem to remember it was a very specialized small sealed lead acid battery.

I tossed one of those in the trash about 6 months ago.
