There are two straight lines--the constant current in Bulk at .25C in the one graph and the constant current in Bulk at .4C in the second graph. One takes four hours and the other takes one hour. How can that be?
If C is 100,
25a x 4h = 100AH and they haven't even started the Absorption stage yet.
40a x 1h = 40AH and then the 15 minute? Absorption stage gets the batt full to 100AH?
I am having some difficulty accepting that this is a sincere question, when the answer is right there in the paragraph you quoted from:

Stage 1 battery charging is typically done at 30%-100% (0.3C to 1.0C) current of the capacity rating of the battery. Stage 1 of
the SLA chart above takes four hours to complete. The Stage 1 of a lithium battery can take as little as one hour to complete,
making a lithium battery available for use four times faster than SLA.
You can charge their lithium batteries at 1C, which is four times fast than 0.25C for lead acid.
I already said that way back. You are ignoring my question about the Stage 1s in the two graphs. What is your comment wrt : (where C =100AH)
.25C x 4 hr =100 AH and the batt is not full yet so how can it be at C?
.4C x 1hr = 40AH nowhere near C.
.4C where C is 100 would take 2.5 hrs with no tapering amps
So either my calculator is broken or this is all more sales BS as you call it, or I have missed how they are doing this comparison.
