you will need an analyzer, I found removing the battery from the car safer, store it on a block of wood then plug in the tender. I think the tender specifies ventilation.

It will most likely be the battery in the trunk. Use the MB charger in the trunk that came with the car or your own charger. This is the normal reaction when the battery is low due to low use or sitting for awhile. If it does not take or hold a charge, go to any battery retailer and get a replacement. Unlike the starter battery - this one is readily available.
