If you have one of these, you can pick any voltage you like and change it when needed to make up your own charging profile. Gets you clear of the unsuitable fixed voltages and charging profiles out there.

BTW people here have been reporting on their Schus over the years how bizarre they are. I would be afraid, very afraid :)
When I saw 8.1V, I assure you, I was!!! Luckily it was about 30 min maximum like that and the battery didn't even get very warm. I never really figured that the Schumacher was going to be the answer, but I had it laying around so I wanted to at least try it.
