SL55/63/65/R230 AMG: Winter Storage
a 15 minute idle will not fix it.
you need to go for a longer drive or better yet - charge the battery with a battery charger.
once you put the car away for the winter always connect a battery tender to the rear battery.
most of us use c-tek chargers which are safe and proven.
I hooked up a trickle charger (1 amp) this morning and it resulted in making all the warning lights on the dash light up so I unplugged it. Any ideas?
