While some people do use their house batts for starting, it''s not a good practice to be in.Deep cycle batts(to put it simply) have thick plates to allow a long discharge time. Starting batts have thin plates to release large amounts of amperage in a short period of time.Batts that are meant for deep cycle that are constantly used to start your engine (especialy a diesel) will loose eficency quicker and batt life will be greatly decreased.People in this practice will find that their batts might only last a couple of years, unless you have a huge bank.Think about adding a batt that is only meant for starting,you''ll be better off.And also charging voltage for a flooded batt should be no less than fourteen and no more than fourteen point two. Incorrect charging voltage will also decrease batt performance and life.
