That should be fine for car battery voltage checks, checking car / household fuses and so on.
There was a good comprehensive guide to the correct voltages over on the Backroom ages ago, I can't find it from a quick search though.
basics are:-
Measure across battery terminals ( engine off) :
12.7 Vdc = fully charged battery
12.0 Vdc = pretty flat.
Start the engine and re-check the voltage, should be around 14.5V, certainly any less than 14V and i'd be suspicious.
whack the HRW and headlights on, voltage shouldn't drop below 14V ish.
Those are off the top of my head, shouldn't be far out though.
As I said before, personally I don't think a year old battery should need top-ups, either it was a rogue alarm or something is not working properly.
