I'll try to find an article but basically the batteries are rated at 10h discharge rate, and at 1-2hr lead-acids (flooded, AGM,Gel, etc) only register 40-50% of rated capacity. LifePO4s can manage 80-90% of rated capacity under similar loads

https://batteryuniversity.com/article/bu-806-tracking-battery-capacity-and-resistance-as-part-of-aging Looks like you lose ~50% capacity while you still have over 75% CCA. Is it why many battery testers would discard battery if CCA goes below 80%?

Just beware that all those charts like from Peter Verdone (and there are many others) have one secret; they're ordered by viscosity at 40C (104F) and unless you are an MX ripper forks operate at ambient temperature. At 20C (78F) viscosity could be 2.4 times higher than indicated at 40C

Does anyone have an idea who/where is it made at? here is a picture of cut off filter: It has markings in Japanese, English and Spanish(?)
