My battery is showing 11.5 which I believe means its discharged. I'm not sure how to recharge it.
Will simply using jump leads from another car and running the second car for n minutes cause the battery to recharge? how long should I leave the second car running for?
Will a car booster work? As far as I'm aware this doesn't recharge the battery like a car battery charger does so won't work?
Can I disconnect my battery and take it to the shop, is there anything they can do to recharge it?
Basically these seem the simplest options to avoid buying a new battery but I just want to know if they may work?
