I have an older analog test meter so I'm not how sure accurate it is. Here's my ST readings.
With ignition off: just under 14 volts
Turn ignition on (headlights on): Monitor voltage for a couple of minutes: Holds steady at just over 12 Volts (A steady drop in voltage means bad battery capacity I think)
Crank starter: Voltage holds steady at 10 Volts (a steady drop also means a bad battery).
I think the battery is OK. The battery I have only has 120 CCA rating so maybe that is why it cranks a bit slow to my taste.
The OEM battery has a CCA rating of 230 amps so I would think that would crank the engine over more quickly.
