2 parts to this question- is one charger better than another? and how can I search

[csport]

First part of the 2 questions, is one charger better than another?
I have lestronics timed and automatic Now- I see chargers by Schaer and DPI and another that call themselves desulfating? and truly automatic-

As for the Desulfating- How important is this when batteries are properly cared for ( which I have not down yet, because I did not condition and four of eight froze even when it only got close to 32-
and I see some listed as truelly automatic and can maintain batteries over the winter, they will come on and maintain the charge or so they SAY they will-
are there any oppinions that you are willing to share?

also

I have forgotten how to do a search on just the ezgo section or is it possible?
thanks so much
