Jimmy Joe,

You haven't proved it to me that weak batteries damage starters. Weak batteries will cause less heating in the starter than good batteries. Starters are run in overload condition and thus will overheat if used too long.

Starters are damaged by over heating. It destroys the insulation and current starts to leak thru it. Then the starter pulls alot of current but does not give enough torque to crank the engine fast enough.

When the engine is hot, the starter is also hot and can not dissipate internal heat fast enough. So cranking a hot engine like when you run out of fuel overheats the starter much quicker than when the engine is cold.


I think you just overheated your starter from too much cranking and that is what did the damage, not a weak battery. It appears that your battery was good enough to overheat your starter, so maybe it wasn't as bad as you thought it was.
