Belkin Residential Gateway 12Volt UPS

I just picked up a used Belkin BU3DC000-12V and I was wondering if my unit is working correctly as I measured the output voltage (On AC Power) as 13.5 Volts DC. Is this correct? I thought is was supposed to output closer to 12VDC? I know that the battery is good (Which is the only part I wanted anyway) I was just wondering as I thought the gateway/modem & router devices wanted a regulated 12 Volts? as I was not talking about the battery charging voltage I was measuring the output from the DC plug that goes to the gateway device as 13.5 Volts DC.
Also can these things be used for anything other that AT&T Uverse?

PS my device is revision A

Perfectly normal. If you measure the output from any of your 12vdc adapters powering your equipment you will find the same. Most devices that have a 12vdc adapter don't actually run on 12v anyway, they step the 12v down to 5v internally, and as such they can handle a wide range of input voltage.

Those UPS units can be used for anything that requires 12v @ whatever current the UPS is rated for.
