I'd guess that the 90A figure in the top section is an error. The lower section shows 360A maximum discharge current for 30 seconds. Also, the discharge time vs. discharge current curves shown near the bottom indicate several minutes capability at 3C (54A) discharge current; this is similar to the 3C capability of the older battery. It appears the new and old batteries are similarly constructed, and that the new one is designed for slightly (~10%) lower capacity. This may be a design trade-off to allow higher short-duration discharge currents. (A little more lead, a little less acid.)

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
