If your battery is an EFB type, you should run a reconditioning program on it using a smart charger, like a CTEK 5Amp one and see if these values u=improve, if you have an AGM battery then not is not possible or useful.
Lack of use is a killer for a battery full stop, if you can use a battery maintenance charger during periods of light infrequent use then do so as it will save your battery.
