But still no answer to Phil's question why you have to push harder. Why is "low and slow" with AGMs not just as good given more time?
You have to push harder because the battery is PUSHING BACK BFL. it's that simple. If you are pushing me and I am pushing you with exactly the same force (Voltage) We go nowhere (Arm Wrestling???)
As for Why is "Low and slow' not as good as given more time??? I think those two terms mean teh same thing. Low and Slow takes more time. Fast and Furious takes less time.
LIFELINE says it "INitial charge" should be at lest 20 (used to be 30) % of the C/20 (That is if the battery is a 200 AH it shold be at least 40 amps) Now that's fast .. Most Wet Cells the REcommended MAXIMUM charge rate is 30%.. OR LESS of C/20.
I was told something one time. If you can't comprehend, then you need to apprehend. In this case, I don't completely understand all this. But I put the mans suggestions into practice and I I wake up with 12.5 volts after running two c-paps and the furnace all night in 24 degree weather. I apprehend and it works.
