I have a double battery setup in my 2251 forester. When fully charged volt meter reads approximately 12.6. When I check volt meter after 24 hours it reads 12.2 to 12.0. I have the battery cut-off switch turned on and the tv plugged in so I know there is some draw on the batteries but surprised that much. Is this typical or are the batteries failing after 9 months? Thanks, Jerry.

Could be either, or both.

Have the batteries load checked.

Then comes the hard work of what is drawing the current. If you can use an ammeter check each DC circuit at the fuse panel.

you need something like this to test the ability of your batteries to deliver consistent power after being loaded and drawn down... also you may have other parasitic loads besides just the TV such as the CO monitor...

It would be nice to know the amount of current in amps that are being pulled by the batteries when connected. Most cheap volt-meters will allow you to put them in series with the battery cable and measure up to 10 amps of current draw. If you have one then use it to measure and not guess what the current draw is.

You say the battery cut off is switched turned on.. make sure is is switched to off. Its kind of misleading as its labeled battery cutoff so it seems to work to cutoff the battery it must be on. So to switch off battery tirn to off...

Use a meter and measure the current being delivered by your batteries with everything supposedly off.
