15V is way too high. I don't know if that is dangerous, but it probably

yes, indeed it is all very upsetting. It overcharged it because its
software locked up.

yes, they are quite heavy.
I would contact the company at the
link I provided and see if you can agree on an acceptance criteria for
whatever charger you determine fits your need.
I have charged a very narrow range of 12V batteries, 50AH to 70AH. Thus

mine are marine deep cycle batteries. i have three: one for my onan
diesel generator, maintained by a 1.5 A battery charger/maintainer,
and two for general purpose fooling around and the boat.

hit the fan if you screw up. Nothing like burning down the house to
save $50 on a commercial charger. When I was designing chargers, I'd

on the power supply, like this
