Some electrician explained it to me before...
I forgot the details but basically keep your charger at 2A and you get the best charge.
I have that same charger and found an overnight at 2A is the goods.
In other words your 75% of the S1 cycle must exceed the 100% of the S. 2 portion of the process....but only if the 10amp fuse was made using a 6 element alloy.
Pm me with additional questions.
