Default DEAD &%#*& Batteries?

Yes, but how? Doesn't it make a difference?

Agreed.
A moderate or low load test over a measured time interval is
easy to do and the best way to rate battery performance.
That's better IMHO than a quick high load test, unless you
are specifically testing start batteries.

Hey in some cases, that's all ya got!

If that's all, not a problem... with the right equipment, of
course.

A good charger is not expensive and makes a HUGE difference
in battery life & performance.
