Hi, my car battery has failed twice In a wk but both times the mrs had borrowed the car . Today she told me she unlocked the doors forgot to use the immobilizer fob tried to start the engine and the battery was dead. I then had to jump the battery,I use the car daily and it's never happened to me, I'd driven 30 miles today before she borrowed the car so the battery should of been fully charged. Do u think I just need a new battery ? is it somethin to do with forgettin to use the fob and tryin to start the engine ?or should I ban her from driving the car ?thanks for any replies
