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 80F (32C). 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."
