Batt life data

As my batt's are getting a bit long in the tooth I was looking at data for replacement. Limited to Rolls as that is what is fitted now. It struck me how different the performance of different models is (same case).
Best life- S-500 357a/hr 6v 1hr discharge rate 121a 4500 cycles to 20% or 2750 to 50% C$440
Highest capacity- S-480 375a/hr 1hr discharge 135a 2000cycles to 20% or 1125c to 50% C$ 375
AGM- S6-370 335a/hr Max discharge rate 50a 4000cycles to 20% or 1400c to 50% C$480

Thought this might be of interest, particularly the difference in life cycles
