13.9 Volts charging is a tad high but in the "ballpark".  The battery's a
"sealed lead acid" type with nominal voltage of around 12.4 to 12.6.   A
good "float" charge voltage is around 13.4 to 13.8. You can test your
battery by disconnecting AC and measuring the voltage drop under a load.
Sealed Lead Acid (or "Gell Cell) batteries are available at "Rat Shack" but
they're on the expensive side there.  It's best to go to a local electrical
or alarm wholesaler where you'll pick one up for around 12 to 15 bux.
