I was going to use the old battery from my jeep, I replaced it last year. Sadly it just won't hold enough charge. I can run a 60watt light bulb off it for about 20-25min. I was hoping I could get about a hour or more using my 200watt block heater. That would make it worth while to haul it in and out of the house. I'm not sure if it's worth buying a new battery for it. That's why I was hoping to test it with the old one.
Would it be crazy to just run it off the good battery for 10-15min before starting? I know it would need to recharge it after starting and that would require more gas. But it would bump the starting temp up 10-15F. Would it counter act whats needed to recharge?
How much power is in the typical car battery anyway? I'm sure the guys making the electric cars would know the answer to this one.
