Confusing isn't it?
Forget batteries that list ONLY Reserve Capacity. It's done to deceive the customer.
The LOWER the ampere hour rating (20 hr rate) while having the GREATER battery weight in pounds (both are needed in this formula)the more cyclable the battery.
Think of battery power measurement as being equated to SPEED in a human being.
Think of battery longevity (cyclability) as being equated to ENDURANCE. Ever see a weight lifter running the 440 meter track? it's pathetic.
The greater the cold cranking amp rating the poorer the ability battery has to withstand repeated charges and discharges. Fast & Furious Failure.
With 2 deep cycle batteries coming from the same company, look for weight comparisons. Water is featherweight in comparison to battery acid or plastic case. Heavier is better.
