Newbie with battery question
After the first quick shakedown trip we parked the trailer, unplugged elec, etc. and left. Now it's been a couple of months. Didn't realize about the phantom draw against the battery but I do no...

So far as I am aware, yes. If you research the history of lead acid you'll find that up until about 1954 all of them were designed to be what we now call deep cycle units. After that other chemistries started to be used. It kind of coincides with the introduction of the alternator vs a generator for cars.
Deep cycle batteries at 85% state of charge have an acceptance rate of about 12.5 amps per 100 amp-hours of capacity. Any more than that and they start to gas instead of charge. This is one reason why for boondocking a modest solar system can be a huge benefit--no one in their right mind is going to run a generator to charge at such a low rate. (163 watts per 100 amp hours)

Flooded deep cycle batteries have more antimony to start with, that is one reason that their self discharge rates are higher than a car jar.
Now maybe we are getting somewhere.
Is that true of ALL flooded deep cycles ?
