As I have a number of vehicles and machines with batteries, I often deal with batteries in poor condition.
There is a theme out there that old batteries in poor condition can be "desulphated".
Apparently, the logic behind this is as follows: as a battery is discharged normally, lead sulphates form due to galvanic action and producing electricity. This is normal. As the battery is charged back, those sulphates are converted back to lead.
If the battery is poorly maintained, (discharged and not recharged), those lead sulphates allegedly form "bad crystals", which are not broken up by charging. So, the battery is degraded.
There are products out there called "desulphators", which supposedly break up those "bad crystals" and convert them back into battery lead.
Information about them, as well as numerous forum discussions, shows some extreme ignorance, lack of scientific validation, as well as claims that are not supported by evidence.
I tried to find some tests, like taking two more or less identical batteries, and comparing results of charging one regularly vs. applying "desuphation" to another and comparing.
Nothing like that seems to be shown. Instead, there is hoopla and nonsense, people experimenting with garbage batteries without any valid "controls" or even valid testing methods.
As this is a vital question for me, due to the amount of batteries I have to deal with, I wanted to know if anyone has researched this issue.
My question is1) Does "desulphation" increase CCA 2) Does it increase reserve amp-hour capacity?
We have a company out here (Battery Sales) that takes old battery cores, does whatever electrical magic, and sells "reconditioned" batteries in exchange for cores. The general conclusion from their own salespeople is that their "reconditioned" batteries are good for equipment that you want to sell right away, but it is not even close to getting a new battery.
I used them for a while and saw their facility.
So... For poor condition batteries, can at least some of them be somewhat spruced up?
Has Anyone here tested "desulphation" equipment?i
