On the other hand, a higher capacity battery may last longer simply 
because 
you're not discharging it as far with every use.  

A good rule of thumb is to measure the amp-hours you usually use in a 
typical day's work, and size the battery so its capacity AT YOUR NOMINAL 
CURRENT is twice the amp hours.

Someone correct me if I err, but I think I recall that an ET chows down 
around 60a when mowing.  SInce RC for a golf car batteries is calculated 
at 
75a, a rough but quite usable approach is to buy a battery with reserve 
capacity that's close to double your required mowing time.  Your basic 105 
minute battery should just about do it, which is probably no coincidence.
