<br>
I used to be able to get used golf cart batteries for about 1/3 the cost <br>
of new ones, and they would work well enough for a few years, so pretty <br>
good deal. I used a simple analog float charger to keep them at full <br>
charge, and used the stock built in charger for the main charging. A <br>
few years back, I got a fancy 36V modern charger, but found that it was <br>
horribly power hungry in idle / float mode, and the float set point was <br>
too high, boiling water away too fast, and NO adjustment!<br>
<br>
The last set of batteries I bought new Duracells from Sam's or BJ's. <br>
They are showing low capacity already, only been a year or so. I've <br>
been using 3 smart energy efficient 12V chargers to keep them at proper <br>
float voltage. Even if I got the expected 5 years under ideal <br>
conditions for flooded cell lead acid batteries, that's about 6x90= $540 <br>
every 5 years. Yikes! And right now, that's not even close to what I <br>
got.. [I have to go gather data to determine if I have one dead battery <br>
/ cell / or the whole set is low output]<br>
<br>
Contemplating looking at other battery types, or an inverter generator <br>
with a big power supply [which I have the parts to build laying around] <br>
to power the Elec Trak.<br>
