Seems like sealed gel cells are what everyone installs with a modern battery charger.
When I got my 1996 450DA it was equipped with 6 year old gel cell batteries and the factory, 1996, 60 amp battery charger which I do not believe has a battery type selector switch.
At that time there were no gel cells to be found in SW Florida, so I did the Wal Mart thing and grabbed 5 group 27 lo maintenance, old fashioned, lead acid batteries.
All 5 installed, and a year later, no issues.
This was how I handled my 10 meter for 21 years, cheap batteries that were changed out at 4 years, no matter what.
So two questions:
1) CAT power and gel/sealed/AGM/lithium/etc batteries with the correct shore powered charger - how does the vintage 1996 CAT alternator not overcharge the batteries while under power?
2) Is the 9kW genny battery charged by the shore power charger, or is it isolated, charged solely by the magneto in the genny?
BEST !
