Gel cell batteries must be charged very slowly. Instead of flat plates like a normal battery they have a mat that is wound like a roll of toilet paper with little space between and much more surface area. The added surface area gives them the added cranking amps. Too fast a charge will warp and destroy these. I think if you go to the Optima website there is info on charging.
