2. Other Threads
Lots of other threads re engjne/starting battery. If there is a particularly good one, please post.
3. Charging
Engine alternator charges engine/starting battery.
In addition, the original Westfalia battery charger will charge the engine/starting battery for 3 hours IF the battery charger determines the engine/starting battery voltage is low.
4. Voltmeter
The central computer console shows the voltage of the coach/house batteries. The voltage readings can also be used as a rough indicator of what the alternator voltage is putting put (if all batteries are mostly charged).
5. AGM Battery
An AGM battery ($200 or more) is usually more expensive than a regular lead-acid battery ($110 or more).
For Westy owners, the AGM battery offers several advantages in handling frequent use of the Espar hydronic heater (when the Espar Airtronic coach heat r is on the blink), heavy radio and other electronic (CB, GPS, etc.) use off engine/starting battery, and frequent offroad or bad road conditions with lots of vibrations.
AGM batteries can take more frequent and deeper discharges and can handle vibrations better.
6. Sears Diehard Gold AGM Group 49
Currently on sale for $145 (so 25% off the higher list price). Three year full replacement warranty.
(Please feel free to list othee good deals, especialky on AGM batteries.)
