As a follow-up, and having heard back from Ahlborn agent in the UK, confirmed - once the acid seeps through the vias or feed-through-plated holes, then the glass fibre has become impregnated, and with it being a multi-layer board (2 trace layers sandwiched inside as well as component and solder sides) EVEN IF a repair worked, it would not be reliable.
The batteries in question have about a 6-7 year life span and OUGHT to have been a dealer recall with design modification to remove the battery from the board and relocate at some distance.
Very sad, and doubtless fairly expensive for a small rural Church at the time, this size of instrument would have been ideal for donation to retirement/care homes, but unless design engineers take into consideration a single life-limiting component, the entire brand name will suffer.
I gather it stopped working about 10 years ago (made in 1999 I think) so not good value.
Otherwise with battery intervention, it would still be good as new and could doubtless last may years.
Replacement boards are not available, so it is terminal.
Ahlborn agent did offer to examine board free of charge to see if it was repairable but mine is considerably damaged all the way through.
Thank-you for a most interesting forum chaps.
