So the undervolt indication of the Schumacher is a safety feature to not boil over the calls on a long trickle charge?
What caused me to question it, was that a 22-month old Batt on the GMC was indicating low volt condition. Before I put the charger on the Batt read 12.05 [Fluke]. I put the mechanical charger on overnight, maybe 12 hours. In the morning it read 11.43, and didn't start without attaching the charger back on at 12/6A, and then it caught.
Assuming the Batt wasn't taking a charge anymore, I swapped it over.

Anyway. I have to take the C/10 in to get the O'RAP kid to check it out. We'll see what he says.
