Charging batteries: inverter vs charger
Going to RMNP next week. No hook ups there, so need to recharge two 6 volt batteries daily. I will be using a Honda 2000 EUi generator. Couple questions: 1. Can I use external charger hooked to batte...

Just to be sure you get your batteries re-charged follow this brochure statement from Progressive Dynamics on how long it takes to re-charge a deep cycle battery. This is battery science so not many ways to get around it...
"Progressive Dynamics ran this test on the amount of time it took a PD9155 (55-amp) converter/charger set to three different output voltages to recharge a 125 AH (Amp Hour) battery after it was fully discharged to 10.5-volts.
14.4-VOLTS (Boost Mode) – Returned the battery to 90% of full charge in approximately 3-hours. The battery reached full charge in approximately 11 hours.
13.6-VOLTS (Normal Mode) – Required 40-hours to return the battery to 90% of full charge and 78-hours to reach full charge.
13.2-VOLTS (Storage Mode) – Required 60-hours to return the battery to 90% of full charge and 100-hours to reach full charge."
NOTE: It doesn't matter how you get the 14.4VDC at a 20AMP or more capacity to charge your 12VDC battery. If you only have a few hours to charge the battery then you need to be using the 14.4VDC level so you can get to the 90% charge state in as little as three hours time.
Just charging at 12VDC or 13VDC levels you can see how long it will take from their brochure. You don't have that much time in one sitting.
If you don't have the smart-mode on board converter then you will have to bring along a smart mode portable battery charger like the Black and Decker VEC1093DBD model and plug that into the 2KW Honda generator 120VAC receptacle and then connect the battery charging cables across the 12VDC leads going to the batteries. Since the portable battery charger is a 40AMP model then it will re-charge two 12VDC batteries connected in parallel or two 6VDC Golf Cart batteries connected in series in the three hour time frame.
