When your alternator is charging the battery it should be supplying in the range of 13.5 to 14.5V or so. If it is higher than that there is probably a faulty regulator.

Your alternator's voltage regulator may be faulty. Check out this info:

Alternator - Holdenpaedia

Here is a quote:
Overvolt or excessive voltage:

If the Output Voltage is in excess of that stamped on the Alternator, it's likely that the Regulator has failed.

Hope this helps. It may not be your battery at all.
