(ET) 12 volt batteries

["wombat" <wombat RealNS com>]

I run a John Deere E-90 that uses 3 12 volt batteries, i don't remember the
make but they were listed as heavy duty marine type.  I currently have
either 2 or 3 years on them, haven/t checked them yet this year but will
next week.  They are run to the point where the mower slows down 
(typically)
before recharging.  They are also on a "trickle & bump" charge cycle at all
times when charged including over winter.  The E-90 uses a drive motor and 
2
mower moters, probably like the E-8 but no motor speed control, just on and
off.
