Horstmann H37 battery replacement.

[Unklian]

Hi Again.

My Uncle has a Horstmann H37 three zone programmer / timer.

These are fitted with a back-up battery.

The battery has a 10 year life and is "non-replaceable"

It has come to the end of it's life and now has to be reprogrammed after each power failure. To save expense (New programmer / rewire etc.), has anybody any information about the battery type or replaced one? We would rather not remove the programmer, have a look and then have to do it all again if possible.

Any information anybody?

Many Thanks.

Ian.

Almost 9 years since your problem, did you manage to fix it? I have the same, and would rather repair than replace.
