I am setting up a small battery bank in my basment to give constant ups dc power to some equipment i have

I got a car battery charger connected to the AC outlet and the DC power
from the charger goes to the battery's, The charger will always be charging the battery's at 13.8vdc, Will this overcharge the battery's ? or should the charger switch off when the battery's is fully charger and charge them again when the voltage drops ?
