Yeoman Battery

[earlybird]

My Yeoman Pro must be well over-due for a new battery. It's no longer marketed and even if Precision Navigation would do the job, I really don't want the trouble and expense of returning it.
Has any-one carried out a DIY replacement. What's involved, any potential snags?
TIA

It's just a normal CR2032, in a clip holder. Dead simple to replace, I did it as a precaution before walling up Kindred Spirit's Yeoman inside the chart table (it was designed to come apart again for future replacement, but would have involved a varnish patch-up).

The only gotcha is that it needs to have 12v power supplied while you change the battery, otherwise it forgets all the stored charts. Someone on here told me that that wasn't the case, and it would only reset the options to factory defaults; having just bought the thing second-hand I thought that sounded good, so I deliberately left it unpowered. Poof, all the charts gone, he later admitted he didn't know what he was talking about and was just going on what "seemed likely"

So, make sure it has power and the swap is easy.

Thanks, just what I wanted. I wouldn't have thought of the power-on tip.
Mine is mounted under a "table".

I wouldn't have thought of the power-on tip.

If it remembered everything with the battery out and no power applied, it wouldn't need the battery in the first place

(It's 1980s memory technology, before flash and other non-volatile RAM, which needs constant power to retain the data.)
