A good battery will measure about 12.8V. If sitting for a month or so it may drop to 12.6 or 12.7V. No worry just normal. Charge it back up and good to go.
Your batteries dropping 0.01 (10mV) or so is no concern. When you measure it with the volt meter, it will be try to accurately measure the voltage but it may be off slightly a bit plus or minus.
After fishing for 8 to 10 hours or so the battery could start get down low enough and your electronics will start to not like the low battery voltage and if too low the electronics will turn off.
The battery you talked about at 9 or 10V is toast.
Hope that helps.
