Replacing a 55 amp converter with a 45?

80 amps for what two minutes? Then you are tapering quickly and will have BFLs sulfation issues requiring extended top charging upon return.

When you do a 50-90 either of the three ways shown in my ugly graph, you still end up at the same 90, so what difference is there wrt sulfation?

I suspect smk still believes there is a "quality" to the recharge using a lower charge rate. I can't see that in doing 50-90s. 90 is 90 no matter how you get there. There are not two kinds of 90, one better than the other.

Yes I do believe when speed charging there is a bit of 'surface' charge to the 90%. I further believe some of the natural sulfation is harder to remove and takes more time that a speed charge does not allow. So you get home and you have to deal with this more difficult sulfation. A slower charge reduces the effect. JMHO
