That explains somethign I wondered about.
NO,there is not an AGM with a 13.1 float. But they still work well with the PDI Wizard jobs.. The reason has to do with another feature of the Wizard (Auto-equalization for a few minutes every day)
Now..one other observation: The 9245 is limited to 45 amps out.. LIFELINE says the initial charge current should be AT LEAST 20% (They used to say 30) of the C/20 rating..Group 31s are 130 amp hours so that's 40 amps FOR ONE battry. You have two.. You need a 9280.
OF course that is only LIFELINE.. most companies want 30% as the MAXIMUM recharge rate. So again a 9280.
