I have improved the APC Battery template and thought I'd share it. Changes compared to the default template you ship with 1.6.5:

• occasional zero values are ignored (using max(120) instead of last(0)) - happens with APC units every now and then
• being explicit about the number of minutes left (10 and 5) running on battery
• added dependency of the 10 minute alert on the 5 minute alert (so the 10 minute alert doesn't occur if the 5 minute alert is active)
• added upsBasicOutputStatus (.1.3.6.1.4.1.318.1.1.1.4.1.1.09 item which tells whether an APC UPS is on line or on battery or in other states.
• added a trigger that fires if the APC UPS loses power and goes on battery ( {Template_APC_Battery:upsBasicOutputStatus.last(0)}

  =3)

• fixed the number of seconds left on battery (you used the value 10 but that means seconds so I changed it to 600 - triggering an alert 10 seconds before the lights go out is pretty useless and probably not intended)

Here goes the template:
