I am trying to build, or at least cobble together, a battery pack for a
receiver. I will only need one (1) amp of power. The battery will have a one
(1) amp fuse on both the lead in and out of the radio just for safety. What
I have not been able to understand is what amp hours are. I need a twelve
(12) volt battery that will last a while, or at least five hours, and be
rechargeable. I have been looking at UPS battery pack, or even small car
batteries. Any help? Thanks.

That is what amp hours is. A 12v battery rated at 5 amp hours, is capable
of supplying 12 volts, and 5 amps, for 1 hour. The same battery can supply
12v and 1 amp for 5 hours, or 12v and 3 amps for 1.66 hours, etc. You could
even use a motorcycle, or car battery if you want. As long as it's still
12v. The greater the amp hours, the longer it will power your radio
equipment, between charges. Make sure the battery is the proper voltage for
your radio!

A note of safety...if you're using a lead-acid battery, such as a
motorcycle, or car battery, make sure it is the sealed type. Otherwise you
will need to provided good ventilation due to the fumes generated while
charging. They can be explosive!
