Re: Do I need a new battery?

replace the alternator with the ones used in modified law enforcement vehicles and the issue disappears.

Nope. Test first, then replace what needs replacing.

Healthy batteries should be at 12.6 V static, with lights on 12.2. Alternator should be charging at 13.2-13.8 V.

i agree, my comment was not intended to be a fix, only solution if the 1-2VDC change is bothersome with a normal battery, alternator and properly auto-idling engine.
perhaps the OP's vehicle is not auto-idling properly with load on the engine ?
