Charge the batteries before placing the batteries in service.
You should do a trickle charge on each of the batteries individually over an 8 - 10 hour period. This will activate all of the surface area of the battery plates. When the battery is fully charged it should have specific gravity reading of 1.265 using a battery hydrometer / tester. You will get that on a brand new battery but that specific gravity reading is only coming from a very small active / working area on the battery plates. Hence you have a very short working duty cycle at the moment.
After your trickle charging session.... wait 1 hour to test the specific gravity of the battery.
I am certain that if you do an extended INITIAL charging period on all 3 of the batteries that your working duty cycle will return to near normal time periods. Let me know if this does not work. There is more that can be checked. For the moment just do the initial charging session on all 3 batteries "WITHOUT using your inverter" as the charging source.
Once thing to note... if the batteries were ever tipped in excess of 45 degrees in shipment they may be lacking the necessary electrolyte level for the batteries to function normally. I.e if they were tipped and then someone just added distilled water / battery water. The batteries will never perform properly.
Lastly.... if the NEW batteries were serviced with electrolyte and water but never initially charged
then you many have a split level battery electrical level. I.e. the electrolyte and water have never initially mixed properly. The too will cause the symptom you describe. Charging the batteries for an extended time causes bubbles in the battery and does and excellent job of properly mixing initial electrolyte levels.
Probably more information than you needed but, anyone using deep cycle batteries for the first time should be aware of the above.
