  1. However a dying battery can overload a charging system especially when it has a shorted cell. As a motorcycle mechanic (where batteries tend to be undersized for obvious reasons) I've seen that fairly often. I load test my batteries (load testers are cheap being basically a resistance wire, switch and meter) and marginal ones get recycled. Batteries are expensive but charging system parts are brutal and regulators/alternators never fail at a convenient time.

  2. You are correct! Weak batteries fry motors and solenoid contacts. I don't do it (mechanic since the later '70s, jets to chainsaws and more).
