That high reading is probably what's called a "surface charge", which can show on a freshly charged battery before it's had any demands made on it. (Especially if your Alternator is putting out 15 volts)

When the battery is put into use (or over a short time), this surface charge dissipates, and the battery level drops back to its nominal 12 volts. This initial drop is normal.

So I wouldn't necessarily blame your meter.
