Car battery/door lock problems
Does an interior light left on in a car normally run the battery down overnight?
Today I had to break into my car, setting off the alarm, as the remote keys didn't work. The garage I spoke to suggested that an interior light had been left on, but I wouldn't expect that to run the battery down overnight.
The problem with the car seems to be due to a badly fitting rear boot lid in a Toyota Prius - the catch doesn't always work well. However, I still wouldn't have expected a problem within 12 hours - so is the 12V starter battery also now at end of life?
