In winter time, it gets worst as headlights are turned on earlier and heater fan are on higher setting. Most vehicle's charging system only keep the battery charged to a point somewhere above usuable level but not fully charged. The trick is to prevent the sulfade from forming on the plates in the first place by keeping the battery "FULLY" charged from day one. Once a battery had sulfaded pass a certain point where ordinary trickle charger won't do, this pulse charger didn't do much either (maybe the battery I tested is just too tired). I have tried that pulse charger, not much different to regular trickle charger except the charge comes in pulses. On the idi forum-agnem-is trying out a charger thats supposed to take care of batterys sulfating-and he said it works-dont remember the name of the system-he was having one of his trucks set for a bit-and thats when the problem developed-it restored his batteris-and this thing requires very little power-uses pulse technology. The question becomes, where do you want to be when they fail? /ubbthreads/images/graemlins/vulnerable.gif
FWI, these trucks will start on one fair battery and one poor battery in cold (about freezing) weather. How much more should I expect?īack to the original question- Any stress on a battery will shorten it's life. I got about 130k and better than 4 years from the OEM batteries. But they also get a whole lot more care than my truck does. If I get 20k miles more (about 8 months for me) out of a set of batteries using a charger, was it worth the hassle of plugging it in every night, or would I be better off to bite the bullet and spend the $150 for a pair of batteries and not have to deal with plugging the truck in? On my motorcycles, its a no brainer, I use a conditioner. I know some of the battery gurus will recommend using the chargers on everything, but I look at the "hassle" factor. These are great for infrequent use vehicles.
Some of the better trickle/float chargers do a great job at maintaining and conditioning your batteries. They may recover for awhile, but they will die in the not too distant future. If you've got batteries that are several years old, and they've been heavily stressed, as deep discharge will do, they're not going to ever fully recover. A higher output charger may only further the death of your batteries, by essentially burning off the electrolyte. It can take several days for a small (re: low output) charger to fully charge 2 batteries.
