Really?

I got this out of my owners manual, can this be right? Is 12.1v really still good?

LOL!

"6.0V = Low"



May as well use it as a door stop at that point! The quality batteries they put in these things, and it'll never see a full charge again after going that low just once.

I like this one. I don't let mine go below 12.

You can cause damage to the flooded batteries by going below 50%. I try to keep mine above 12.1 at the lowest.

I don't think any 12 volt item would function at 6 volts. The manual must be a joke!

I ignored that part. A few pages earlier, the manual says:
"A fully charged auxiliary battery will read 12.7 volts DC and 1.265 specific gravity at 80°F (32°C). The auxiliary battery is considered discharged at 11.89 volts, and dead at 11.65 volts. If the voltage drops below those levels, irreversible damage can occur. Typically, a deep cycle battery has an amp-hour rating of 75-100 amps."
