Korg poly 800 battery replacement
The last thing you want is the battery to leak and take out some expensive (and rare!) components with it. This is doubly true if the machine was manufactured in the early ‘80s before they started using the more stable CR2032 batteries. It’s therefore a good idea to open any vintage gear you buy as soon as possible and assess the health of the internal battery. And if you happen to have a Korg Poly-61 or other, older model, that battery could be rupturing and corroding the PCB as you read this. If it hasn’t died yet, it will very soon.
It’s quite possible that the Yamaha DX7 you’ve just bought on eBay still has the original battery in it. The trouble is, these are only rated to last for a few years. Usually a CR2032 three-volt coin-style battery (although not always, particularly on older models), this is attached to the PCB and makes sure that your carefully created patches (and sometimes the factory patches as well) are still there the next time you power the instrument on. However, the synthesizer requires an internal battery to save the patches while the machine is powered off.

This soon became the norm and most every synth since has had patch memory. Dave Smith changed all that by creating a synth that remembered your settings. Why Does Gear Need A Battery?īefore Sequential Circuit’s groundbreaking Prophet 5 synthesizer, if you wanted to save a patch you had to physically jot down settings on a piece of paper. We’d like to cover them all in future installments of Hardware Focus, but this time, we’re going to look at perhaps the number one issue facing owners of vintage synthesizers, drum machines, and other hardware: the dead internal battery. Things like cleaning, refreshing key contacts, and working the noise out of potentiometers are all fairly easy to do. Thankfully, some basic repairs can be done at home and with a minimum of technical fuss. An internal battery in need of a replacement.
