THE WHOLE THING!!!
Most manufacturers say any direction but upside down, IIRCYou can run sealed AGM batts however you want.
In fact, this is directly from powermaster's website:
# Ultra low internal resistance
# Non-spillable AGM design
# Can be mounted in any position*
# Vibration resistant
# Rugged ABS case design
*Upside down not recommended.
