Ok yes they do say absolute maximum. Ok next questions.
Is a float charge only required if the battery is left unused for a long time?
Say i want to charge my battery in 2 manual steps, 1.....bulk charge(constant current) and 2.....topping charge(constant voltage). how exactly would i go about doing this. please correct me if i am wrong but can i not supply a constant current and constant voltage right from the beginning? this probably might just slow down the charging process but then i will be able to do the bulk charge and topping charge without any changes in my electric circuit?
