People ask us every day, why 6 volt RV battery? And why are two 6 volt deep cycle batteries better than two 12 volt batteries?
A 6 volt battery for RV is actually a golf cart battery because they have thicker plates inside than a 12 volt deep cycle battery.
With a thicker battery plate, the 6 volt battery is able to deliver more long term energy and sustain deep discharging and recharging.
If your RV lifestyle is traveling park to park then 12 v deep cycle battery with 80 – 100 amp hours will work fine. But if you camp in remote places and need as much stored energy as possible, you should use two, four or even six 6 volt batteries = 225 ah & 450 ah respectively.
We created a Good, Better and Best guide to help you select the battery to fit your budget and application

How to Test Batteries
Voltage on a fully charged battery in good condition will read 2.12 to 2.15 volts per cell (about 12.75 volts for a 12 volt battery, or 6.40 for a 6 volt) Specific Gravity Readings to determine State of Charge:12.75 & Above = 100% Charged
- 12.60 to 12.74 = 85 to 100% Charged
- 12.40 to 12.59 = 75 to 85% Charged
- 12.20 to 12.39 = 50 to 75% Charged
- 12.00 to 12.19 = 25 to 50% Charged
- 12.00 & Below = Fully Discharged
When you test a battery with a hydrometer, you are measuring the amount of sulfuric acid in the electrolyte. If your reading is low, that means the battery chemistry that makes electrons is lacking.
Q. So, where is the missing sulfur? A. Resting on the battery plates waiting to be released back into the electrolyte when the battery is recharged.
