Recharging a car battery
My burning question is if I can recharge a car battery with a 12 v 5 Amps DC energy source. The car battery is a 12v 70 A standard battery, i think it uses Lead. I am asking because i do not have any experience in recharging car batteries and i know that mobile phone batteries can explode if you do somenthing wrong, so i want to get it right the first time with a car battery. Thanks.
