Hello dgc-ga, and thanks for your question.

There's a good battery comparision chart at:

http://www.battery-usa.com/superior3.htm

It includes automotive, as well as other batteries for use in lawn
mowers, etc.

For the automotive batteries, weights range from 27 to 47 pounds, with
a typical battery weight of 34-36 pounds.

The reserve capacity of the automotive batteries ranges from 60 to 150
minutes, with a typical value of 80-90.

A definition of "reserve capacity" as given by Sears at:

http://www.sears.com  (type the term in their search box)

is as follows:

Q. What is Reserve Capacity (RC)?  

A.  RC stands for Reserve Capacity. Reserve Capacity is defined as the
time (in minutes) that a battery at 80 F will continuously deliver 25
amps before its voltage drops below 10.5 volts. So, if you have
accidentally left your headlights on you may still have enough power
to start your car.
