                    Gel batteries are non-ventilating and do not leak acid. They are well worth the extra money and give less hassel. If properly taken care of , they will last much longer than reg. acid batteries.Gel batteries are made to be charged an discharged many times without warping the inner plates causing weak or dead cells.
                    Regular batteries have ventilation caps on them. This can causes spillage during rough weather.If you have them in a inclosed compartment, in time , they will cause corrosion and detiriorate the metal,paint and wood in the compartment.
                    Preventive maintenace: spray paint or grease the terminals(will keep corrosion off). Brass terminals , last longer , have stronger current flow and are less corrosive conductors.Keep Battery and holder clean and free of debree.Always go for the highest cold cranking amp posible in your battery size
                    I`ve been in the auto industry and have sold batteries of all types my whole life. Interstate in my opinion is the best automotive battery.
                    Hopefully this will help on your next battery purchase.
