A fellow EV motorcycle enthusiast highly recommends a desulfator to extend the life of lead-acids --

... based on his experience and information from what he calls the "battery bible"

Sulfation is covered on the subpage http://jgdarden.com/batteryfaq/carfaq16.htm

Anyone have experience with how well desulfators work?

Mark,

I have gotten 3 years and 15,000 miles out of my trojan J150 batteries.
Since early this summer I can no longer make a round trip to work and home,
but I can charge at work, so they are still 'usable'.   One charge a work
day most of the year(250) and 2 a day for Dec-Mar, means nearly 9000[sic]
cycles.  The batteries are heating up more now during charging and venting
a little acid. Im holding off replacing them to see if LiFe drops some
more...  Keeping my fingers crossed.

I draw around 100 to 180 amps from the batteries during my trips, up to 300
for brief acceleration on to 183.  Car would hold 60 mph up and down hills
on north 183 untill revently, now it drops to just under 55 up the great
hills overpass.  I still only use about 40-42 amps a day from the
batts(averaged 270 watthour/Mile).  Max ah used during a range test was 95
when the batts were about a month old. The geo is about 2800 lbs with the
batts.  About 40% overall average depth of discharge,

I dont have a 25 amp load to test the batts with, so I cant compare to
published data.  

This is all DC efficiency metering,  I have an inductive clamp AC amp
meter, I should make a  power cord one of these days before I replace the
batteries to see what the AC efficiency is.........before and after.

how is your daily draw vs capacity?
