One element screws in and the other bolts onto the heater tank. I have made repairs to an Atwood on two occasions and the screw in heating element is not hard to service, and since your water heater is inside a storage bench it should be easy to access. All power should be disconnected before working on the water heater.

For checking the battery:
In addition to a multi-meter, a specific gravity tester is de-rigeur.
First you check the water level by removing the tops of the cells.
It should be just at the bottom of the 'well' just touching the plastic well bottom. If not, then using a syringe, add DISTILLED water to the cells until they are full as above. Charge for 24 hours; then..........
..........check the S.G. by squeezing out air from the bulb and sucking battery fluid into it until the float bulb 'floats. It should read between 1250-1300 for a fully charged battery. [In the green or green/yellow zone.]
If readings are not to spec, take it to a battery outlet to have it checked for condition.
