2 6V in Series Last Longer: Batteries & Boxes

TWO 6V BATTERIES IN SERIES for 3124KB lasts much longer than 12V.
Battery box mounts on battery rail behind propane. Plenty of height clearance and rail at narrowest part is 247/8 inches wide so all boxes below will fit.

6V BATTERIES My experience is Interstate last longer and specs are more accurate than others

What is the best way to charge my deep cycle battery? [Copied from TM user website]
1. The electrical capacity of the battery charger determines how long it will take to charge your battery. In most applications, a 10-25 amp charger is recommended. First, determine the battery's state of charge using a hydrometer, voltmeter or state-of-charge indicator.
2. Check electrolyte level before charging. Add distilled or good quality drinking water if the electrolyte level is below top of the plates.
3. Follow the instructions provided with charger. There are many chargers on market, each with their own features.
4. Be sure the battery is completely recharged. Use a hydrometer to determine the percent of charge, following the manufacturer's instructions.
5. Recharge within 24 hours after each use. Discharged batteries can freeze.
6. Do not overcharge your battery. Overcharging causes grid corrosion and reduces battery life. A charger with a timer switch is best.
7. Do not use a fast boost charger. A slow charge is best for a deep cycle battery.
8. Unhook the charger when the battery is fully charged.
