A fully charged battery is 12.6 volts.
Have you ever fully charged the battery after purchasing it?
Batteries are typically undercharged when you purchase them.
There are many internet sites that suggest that 12.4 volts is the lowest voltage a charged battery should go down to before it needs recharging. Below 12.4 volts batteries start to sulphate which in turn shortens the life of the battery..
In summary your battery volatge readings are at the minimum reading for a “charged battery”. If you have a battery charger you should consider charging it so that you know it has had a full charge and you can then monitor the “resting voltage” over the next few days.
