Battery goes flat after standing for only a few days. New battery fitted but still same. Is something draining it? there's a lot of electrical/electronic stuff on this vehicle that uses battery power but the battery fitted is the correct one according to the RAC who came out to get me started.
I mentioned it to a friend of mine although he's not a mechanic he's very knowledgeable about car faults and issues. He seemed to think it could be the alarm system that's constantly operating even though the vehicle is turned off. He also recommended I get a solar charger and leave it on the dashboard to help keep the battery topped up.
