Subject: (ET) How do your batteries die?
I bought a complete set of U.S. Battery batteries about 5 years ago.
Only 1 of those 6 is still alive. After talking to the U.S. B.
people, and this list, I think I should have been charging them
harder/longer, but I'm not sure that relates to my question:
Every one of the dead batteries read about 4v when it expired, and
couldn't be charged to much over 4v. This implies to me that a cell
shorted. I would have expected the more likely scenario would be for
each battery to just get weaker, i.e. still charge to above 6v but
not hold a charge for as long.
Am I thinking about this correctly and is my experience typical, or not?
Thanks.

Hi Thon;
Yur experience IS typical. But ask yurself ; How much did you USE
yur Badd-eries? How many miles DID you get out of them, 20k is a
decent range, or lifespan. I went through a pack of T105's in about
20k mikes a set of T-145's a bit shorter? But batteries have a
perverse anamosity; One dies, and the others think, in their lead
lined minds" I'm outta here, too!"In that you got 5 years is pretty
good, but you MUST have lost abourt all your range long BEFORE now?
Did you water them with store bough Distilled water, keep them
charged, etc? It's pretty normal for Newbees to kill off one or two
sets as the learning curve develops? Don't feel bad. Hell, the care
and feeding of Batteries isn't rocket science. They are like Sheeple;
Like to be kept clean, watered and charged. Not much else can you
really do!Oh don't run them DEAD, like car won't move, etc?
YMMV!
Bob
