| 1105507 | 2010-06-01 11:47:00 | I have started a car using a 12 volt 7 A/H SLA battery in not very good condition. I didn't connect it via the cigarette lighter though, I banged it straight across the battery terminals. The car started no problems, but the SLA battery was totally stuffed afterwards. I can't see a 12 volt SLA 'charging' a flat battery, at best it might put sufficient float charge on it for a start if the motor is in good condition, backed up by whatever current can be supplied directly via the lighter socket during the actual start. If the vehicle battery is really low it wil suck a solid current out of the jump battery so the car may not get enough juice to start. As the old proverb says, you can't get a quart out of a pint pot. Cheers Billy 8-{) |

Cheers Billy 8-{) thats all thats in those jump start pack. just a 7-14ah SLA battery. they are enough to get a partly discharged vehicle battery up enough to turn over the motor. don't forget most cars have really small batteries. |
