When does battery need replacing?
Hi all, it's been a while! I've got a 2012 F30 320d and I've never replaced the battery since having it from new. It's very low mileage - about 35,000. I was away for over 6 weeks until last week and the solar trickle charger I connected to the OBD port doesn't seem to have worked; the computer was complaining about the battery being discharged when I started it up, and it's still not happy because I haven't done a run of more than 20 minutes in it yet.
Last time this happened it settled down after I'd driven for an hour or so - but I'm conscious the car is now only a few months away from being 7 years old. Will the computer tell me when the battery needs to be changed? Or does it need changing after a certain amount of time regardless? I don't want to swap it out prematurely but obvs also don't want to get stuck.
