Coach Batteries
The coach batteries in your Aktiv are standard sealed AGM (absorbed glass mat) batteries or optional Lithium battery packs. Do not attempt to
open them. There is no user maintenance possible on these batteries except keeping them charged. Refer to Power Management supplement on
consumer website for more information.

Battery Disconnect Switch
The battery disconnect switch provides power to all 12VDC appliances, such as the water pump, the refrigerator and so forth. Even the propane
cooktop uses 12VDC to run the burner igniters. This switch should be off when you are not using your Aktiv and on whenever you are driving or
camping. The "Battery On" light next to it will indicate the position of the switch.
Charging Your Batteries:
Inverter Charger
Your Aktiv is equipped with an 2,000 watt inverter charger which converts 110VAC (household current) to 12VDC when you are connected to
shore power. This 110VAC power is used to power your 12VDC appliances as well as charge your batteries. Whenever you are receiving either
source of 110VAC power, you are charging your batteries. When you are boondocking and you do not need 110VAC power in the coach make
sure that your inverter is turned off at the panel. The inverter takes power to run so if it is left on it is using power from the batteries.
Underhood Generator
Your Aktiv is equipped with an underhood generator. It is mounted to the vehicle engine and is operated by running the vehicle engine. The added
underhood generator charges the coach batteries whenever the vehicle's engine is running, which means you are also charging them as you
drive. You will arrive at your camping destination with fully charged coach batteries.
If your coach batteries are low, start the vehicle engine and let it idle until the batteries are sufficiently charged. Usually 30 minutes of idling are
enough to restore moderately depleted coach batteries to a useful level of charge. Your charging time will vary depending on the amount of
depletion.
Always close the rear windows of the vehicle and turn off the roof ventilation fan when you are running the engine, to avoid exhaust from
entering the vehicle's interior.
