Chaging Batterys on a SL500 R230

Hi. I’m preparing my SL500 for the winter and wonder about one thing.
I have mounteda battery charger on my consumer battery to keep it in good condition.
When I charge the consumer battery dose the front startbattery get charge at the same time?

Charging battery

No, they are NOT connected.

So you'll have to charge up the front battery (starter) aswell, but only a few times during winter.

Note: The starter battery is only used for starter motor armature and back up power for the system circuit, so it is almost not draining at all.
