As a previous post says, the battery can be quite a critical item in how some vehicle electrical systems work in practice. Generally speaking cars have tended to become less sensitive more recently (due to the extra complication and therefore the need to be more robust to variation), but 15 or 20yrs ago quite a lot of systems could be a bit fussy, if they didn't see quite the voltage (value, range, stability, recovery after start etc) they were expecting it could upset how they worked.
Have a look at your battery, there will probably be a date code on it somewhere, very often a week/year 4 digit code etched into the casing, like 2612 or something (week 26 year 2012).
If it's more than a few years old it might well be worth getting something like
https://www.tayna.co.uk/car-batteries/yuasa/ybx5054/ , (double check it's the right one for your car!!) even if it doesn't fix your problem you won't have "wasted" much in the big scheme of things. If it solves it, it'll be a cheap simple fix. Based on the earlier report of a fix it sounds promising.
A lot of folk on this forum have had very good service from Tayna, including me. Generally next day delivery.
