If the battery discharges after only 10/20 minutes then it's not in the best of health.I have laptop connected for around 10/ 20mins using hex V2 , think it might be because drls are on and maybe even battery needs changing . Funny thing is when i put jump leads on the other car only needs to idle for a min or so and bang she kicks back in .
Do your DRLs not shut off if you set the hand-brake?I have laptop connected for around 10/ 20mins using hex V2 , think it might be because drls are on and maybe even battery needs changing .
