I have had a 2013 Subaru Forester XE petrol, which I bought second hand from a Subaru dealer, for a few months. It is an automatic (CVT) with stop start technology. I didn't drive it for around a month and it appears that the battery in the car has gone flat as it will not start and the remote key will not work. The car is in my drive at home.
I am assuming it is not the battery in my car keys, as I have two and it seems unlikely that both batteries have gone flat at the same time!
Luckily I joined the RAC through my insurance and have cover at home if I breakdown. My main question is, if the battery needs replacing, do I have to get the ECU reprogrammed at a Subaru garage? As I read with AGM batteries this may be necessary. AGM batteries are quite expensive, I would prefer to avoid having to pay to have the ECU reprogrammed as well! I also read that you should not jump start AGM batteries.
I know little about cars. I past my driving test a few months ago (I am 56). I just want the Subaru for driving out to the countryside and shopping. So far I really like it, apart from the battery problem.
I may get either a solar charger or an intelligent trickle charger, as I have read that the battery is likely to go flat if left for any length of time.
Is it safe to use a trickle charger from the mains to my car outside?
I am waiting for the RAC to arrive, maybe I will be lucky and the battery won't need replacing!
