Batteries
riiiiiiiight erm i read this and re read it and you know what i have no idea what any one is talking about, not i hasten to add that they arent talking total sense, its just me!!! ive two red top optima for starting and a yellow top optima for the rest on my 80 and theyve been perfect..i think its a case of ignorance is bliss!
I dont contribute much mainly because i know F**k all but ive loved reading all of the threads and never cease to be amazed at peoples knowledge and their willingness to share it..thanks to all..thanks to john for asking the questions that i wish id thought to ask and thanks to julian for all his work! how he finds time as well to create children ill never know (hang on i vaguely remember how to do that!)
a happy christmas and an interesting new year to you all ..
right!!! back to the batteries.. John would you ask please whats the difference between voltage and charge level.. on second thoughts ..ill just ignore the damn things!!!
regards
