Yep, there are two ways to reduce sultatation. 1. Give the battery a good load. Something like 10A for 20 minutes. Watch out the battery will boil. This will shake the cristals lose and they will sink to the bottom. 2. Add some Ethylene Diamine Tetraacetic Acid (EDTA) to the electrolite this will disolve small cristals Commercial names of this are 'YUASA sulfate stop','Longa-batt',.... You can order this from www.pureresearch.co.uk (no affiliation). I am not so shure about 1. I know 2 will work, I asked my brother who is a chemical engeneer. If you try this please keep me posted. Both methods will restore some of the capacity of the battery. Don't expect miracles. If you add EDTA to a new battery you may extend battery life with 20-30%. Johnny-from-belgium
