Why should I switch to golf cart 6v batteries
Can anyone explain in plain easy to understand language what practical benefits you derive from replacing 12v coach batteries to 6v golf cart batteries? I currently have 2 group 24 (95AH) batteries ...

Oh Goody we get to talk about plates and pastes. BTW antimony was used up to 7% with Pb as a plate allot stiffener. Well, here goes...
Phase composition of the paste. It depends on H2SO4/LO ratio (LO is the oxidized lead powder), temperature, additives and time of mixing. It has been established that the paste is a non-equilibrium system consisting of crystalline basic lead sulfates and oxides, and amorphous sulfate-containing components. Depending on the temperature of preparation pastes with the following compositions are obtained:
At to<60oC
H2SO4/LO ratio up to 12%. The paste contains 3PbO.PbSO4.H2O (3BS) + tet-PbO + orthorhombic-PbO + Pb. Maximum content of 3BS is obtained at 10% H2SO4/LO.
Over 8% H2SO4/LO ratio, mostly PbO.PbSO4 (1BS) is formed.
At to>70oC
H2SO4/LO ratio up to 7%. The paste contains 4PbO.PbSO4 (4BS) + tet-PbO + orthorhombic-PbO + Pb. Maximum content of 4BS is obtained at 6.5% H2SO4/LO. At beginning of mixing 3BS and orthorhombic-PbO are formed first. Then (3BS) + tet-PbO + orthorhombic-PbO react and 4BS is formed. 4BS nucleation is the slowest process. It depends strongly on temperature. In the presence of surface active additive(s) (expander(s)) 4BS and orthorhombic-PbO are not formed at all.
H2SO4/LO ratio between 7% and 12%. The paste contains 3BS + 1BS + tet-PbO + orthorhomb-PbO.
With time of stirring 3BS crystals grow up to 2-4 ?m in size^ and 4BS ones reach sizes of up to 20-50 ?m.
