The original battery on my 2007 coupe is dead since the car has not been driven for about six weeks. The car is parked where jump starting is impossible.

I do have a battery charger. I ma concerned about charging the battery since the car has a smartkey. If I disconnect the battery for charging will the smartkey be affected? Can I charge the battery with the battery connections in place?

What are your recommendations?

Thanks.

 

mine went dead while sitting in the garage over the winter. I hooked a trickle charger to the batttery without disconnecting the terminal cables and my battery was fully charged the next day .

 

Not sure if this is any help, but when i took my car to the dealership last week they charged my battery up.. they didn't disconnect anything.. they just charged it while on the car. I don't know if that is the right way to do it.

 

There's no reason to disconnect the battery, if you're going to drive it get a jump if not just use your charger. Make sure you know which of the terminals is + or - mixing them up would be a major problem.
