The articles I read also said the lower amp charge will extend the life of the battery and the higher amp charges will shorten the life of the battery. One article stressed the importance on charging the deep cycle battery soon after use to extend the life of the battery. Most everything you will need to know about what type battery to buy and how to care for the battery can be found on google.

Not true. There is no such thing as a deeper charge. 10-15A is just fine. Lower rates prolong the time the battery remains discharged and can cause sulfation to be worse. Some batteries need to be charged at much higher rates, as high as 40A.
