One final question?
Looking online at Sams and noticed the Ah rates for the 2 below batteries. I assume the Ah rating for both of the below is 20 amp hour but what does the second number represent? (20 amp hour rate: 75) and just looking at the 2 below specifications which one is the better battery and why?
Specifications
•20 amp hour rate:75
•Battery Electrolyte Composition:Acid
•Battery End Type:Top Post
•Battery Purpose
eep Cycle
•BCI Group Size:24
•CCA at 0 degrees F:500
•Contents:ONE EACH
•Freight Class:65
•MCA at 32 degrees F:615
•Minutes at 23 amps:150
•Minutes at 25 amps:130
•Polarity:Left Positive
•Terminal TypeIN
•Volts:12
Specifications
•20 amp hour rate:55
•Battery Electrolyte Composition:Glass Mat
•Battery End Type:Top Post
•Battery Purpose:Starting Lighting Instrumentation
•BCI Group Size:34M
•CA at 32 degrees F:890
•CCA at 0 degrees F:775
•Freight Class:65
•Polarity:Left Positive
•Reserve Capacity:120
•Terminal TypeIN
•Volts:12

Pesky s are making a mess out of your post lol
The first battery is 75 amp hours. "20 hour rate" is the rate at which Ah ratings are typically measured at (in other words, the maximum amp hours the battery will provide over a 20-hour period). The total Ah of all lead-acid batteries (wet or AGM) varies depending on how quickly you use up it's capacity (pulling heavier current from it will lessen the Ah somewhat).
The first one looks to be the one you want, as it's rated for deep-cycle use (the second is rated SLI, so while it'll most likely power your fan no problem, repeated discharging of a SLI battery will wear it's thinner plates faster than those of a battery designed for deep-cycle use).
