Its probably not the battery, its more than likely the alternator that isn't keeping the charge, to check it turn your car on and the unplug the battery, if it stays on then its something else, but if it turns off then get a new alternator
Yes, a lawn tractor can be jump started with a car battery, in the same manner as another car can be jump started.
Jump start car and do not run heater with engine not running.
Best guess would be that you have a short to ground somewhere that is draining your battery.
It sounds like you have a break in the wire which connects your alternator to your battery, get it checked out.
Dead battery?
You would fry the vehicles computer and risk a possible explosion of the battery.
i got a 2007 mercedes benz e350, battery is dead and i need jump started but i can't open the trunk and get do it from the battery, is any other way to jumped?
Dead or weak battery Loose or corroded battery cables Excessive starter drag
almost all vehichles can be jump-started by using the battery terminals instead. so try putting the cables on the end where the wires meet the terminals. (over the screws that hold the battery connectors on the battery.)
Each step from first to last is presented in order
Take it to a mechanic. You might try charging the battery or borrowing a battery or car to try jump-starting.
This usually means that you have a dead battery. Either from a bad battery, or a bad alternator.
