The Desulfinator
An inexpensive lead acid battery desulfator

One of the best investments you can ever make.

Build an inexpensive lead acid battery desulfator to keep your batteries healthy, or resurrect old sulfated batteries.I have even salvaged batteries from the scrap heap ready to be send back for recycling. Works on 6 and 12 volt batteries. Also sealed computer back-up batteries and gel cells!

Only 8 electronic components; one common IC chip and one common transistor
All parts are easy to find (Radio Shack part numbers included)
Fantastic if you are a fleet owner, have a used car lot, golf course or solar farm.
In more than 4 years of testing it has "repaired" about 90% of the batteries tried.

You will receive detailed instruction with drawings tell you how to build, use, and get the most from your lead acid batteries.

 Was $15, now it is "beerware". (Donations accepted)
