Would a DVM be sufficient enough? For example, I measure across the -/+ when cold and off and i get ~12.37 VDC and when engine on i get about 14.35 VDC. Would be an indication of battery state? Would the Hydrometer test described above show something the DVM doesn't? of course I could just easily take the battery to Sears or auto parts shop for a thorough test as well, but wanted to see if i could do the testing in the convince on my garage and without having to take the battery out etc...
