control panel battery indicator

Our battery indicator says 2/3. What should it say? Are we doing something wrong?

From my manual is says that would be 11-10 volts.
It is sort of lame and I will put in a volt meter eventually.

I have no idea what 2/3 means in your RV. If these indicator lights go from green to yellow to red, you are ok until it goes red. Then you need to fully charge. When you are hooked to shore power, it should always be green or 3/3 or Full. If it isn't, your batteries are not being charged.

The first tool any RVer should get is a volt meter! If your charger is working, the battery should read at least 13.2 and up to 13.6. It depends if you have a multi-stage or a single stage charger.

When not on shore power and no load on the battery(s), they should read 12.8 volts if fully charged. Once they reach 12.0 volts, they are 50% discharged. Letting them go below that or leaving in that state will begin to do damage.

Ditto what the others said. Get a volt meter and test those batteries directly. The internal panels of the type that you have (the ones with 4 lights) are notoriously inaccurate. We gave up relying on ours years ago. Better to measure directly or install a more accurate battery monitor.
