Battery Charging / Battery Voltage

I have just changed my house batteries to 3 of the 225 aH Gel Cell batteries, which are charged by a Mastervolt 70/12-3 charger. At my dock, plugged in with the charger in operation at a "Float" charge rate, my battery bank display is indicating 12.35 volts. When running the water pump, with a couple of lights on, the battery bank is indicating around 12.2 volts.

The Mastervolt charger display indicates 13.45 volts being provided to the battery bank under the float charge rate.

I have always assumed that with the charger on, the battery bank should read over 13 volts. Should I be concerned that the charger is not working correctly?
