OBERHEIM SYNTH

Hello

I have a Matrix-1000 (cream face model) and would like to replace the stock solder leads battery with a holder/standard coin cell.

Does anyone know the correct holder part or has done this prior? Can anyone advise what information/specs I need to order a battery holder for replacement. How to measure leads distance and correct voltage for instance. I have some experience in soldering and appears easy enough but my understanding of electronics and what I need specs wise is limited.

I always wondered why so much synthesizer users want to exchange soldered battery for battery holder, and use standard batteries... It could have some sense when the battery has to be replaced for the new one each month, or let's say, once in the year.

But when I consider that batteries in the most of my numerous instruments still work well after 25 or even 33 years, I really don't see any reason to do such replacement :-)

If battery needs replacement, I use again the soldered battery - it's the same soldering effort, and it will last another 25 years (that means probably it will survive me).

Hi.

The correct voltage should be very easy to find out: just read it from the battery you are about to desolder ;-)

I did such a job in my GEM S2 Turbo and put a CR2032 with holder in it... no big deal, as long as you have enough space in there...

Let us know what/how you will do!

BR,

Flavio.

Hello Matrix-People,

If battery life ends on a synth I always replace the original battery with a holder. It simply is the same amount of work and makes future replaments easy. Hold in mind that the battery life is very dependend of the synth / gear model. E.g. my Motu Timepiece(s) need a new one every two years, others last about 12 years (Korg Z1) and so on. On the Matrix it is easy enough and feels good to have memory working properly.
A standard holder like below fits perfectly.
A helpful page on different synth is this one:

Hi, Flavio,

this can be valid argument, because it's quite possible the quality of older products was better than the recent Chinese cheap imitations :-) But I haven't any detailed and deeper information concerning this - the answer can be found after another few years of using it...

From this point of view it can be good idea to use battery holder - the next battery exchange will be easy.

If I understand well the backup battery is loaded a little bit (if it's technically possible) when the instrument is switched on, and RAM chips don't need much current to keep their contents - probably that's the main reason why battery can last so long time.

Hi Daniel,

your thoughts make sense. But isn't it that the new CR2032-like batteries are less prone to battery leakage, and therefore preferred when desoldering old/used batteries? I9;m not sure this is true, it's a simple question... ;-)

Also, I would think that having the correct voltage is very import as they arent all the same. Its worth noting installing a battery holder with different specified voltage can permanently damage your equipment I would venture to guess.

Maybe I will propose and post this at Gearslutz likewise or someone else can start it if they like. To my knowledge the DX7 series, Matrix 6/1000, QS, Z1, Alpha Juno/MKS-50 and more all have soldered batteries.

These are very popular instruments and would think there is interest in having this reference info.
