What to Look for When Buying a 6V RV Battery
Novice motorhome owners often find choosing the best 6v RV battery for boondocking challenging and frustrating. There are plenty of options that look virtually the same. However, you can simplify the process by considering the following things when buying a 6-volt battery for your RV.
The first thing you have to determine is the battery type: flooded or sealed lead-acid (SLA), also known as valve regulated lead-acid (VRLA). Both batteries have their respective pros and cons that can help you determine which type is best for your needs.
Most RV owners prefer sealed lead acid or VRLA batteries because of their maintenance-free design. You can place the battery in almost any orientation, never worrying about acid leakage. They are also smaller and more lightweight than flooded batteries. Unfortunately, they do not last that long and are less tolerant of overcharging. They also tend to be more expensive than flooded batteries.
If you choose VRLA batteries, you have two options. One is absorbent glass mat (AGM) batteries that are vibration-resistant. They also have higher discharge and recharge rates than the second type of VRLA battery – gel batteries.
The advantage of gel VRLA over AGM is its slow deep discharge. Gel VRLA batteries are also more resistant to high temperatures. Unfortunately, they are more sensitive to overcharging effects.
Flooded batteries are the most common battery type you can use for your RV battery setup for dry camping. They are less expensive and are more durable than VRLA batteries. The downside is that the risk of acid spillage and water loss is high.
On average, a 6-volt battery for motorhomes and off-grid applications has a float service life span of four to eight years. Flooded batteries tend to last longer than their VRLA counterparts. However, there are a few AGM batteries that can last up to 10 years.
The power you need for your RV house battery depends on the number of appliances that will rely on battery power. It is always best to consider these appliances’ amperage requirements to determine the ideal battery power you need to buy.
The good news is that 6-volt battery systems are energy-dense. They pack more energy in their small and compact housing than 12-volt batteries. Most 6-volt batteries have an amperage of 200 Ah. It is enough to power several appliances at a time, especially when you put together two 6-volt batteries in a series to produce a 12-volt output.
Motorhome manufacturers design battery compartments to accommodate 12-volt units, not 6 volts. It is essential to recognize that 6V batteries are taller than 12V units. You may have to measure the battery compartment’s dimensions to check the maximum battery size you can fit.
On the other hand, getting an AGM battery should not be a problem since you can place it on its side.
Six-volt batteries are more expensive than 12-volt units. That is why it is not a wise option for budget-conscious RV owners. However, given the batteries’ longevity, they can be more cost-effective solutions in the long term.
If you are working with a tight budget, you might want to get a 6V flooded battery. An AGM model is perfect if you do not have price concerns.

Hence, the 6CS25P can deliver 115.6 amps per hour for ten hours or 57.8 amps per hour for 20 hours. Meanwhile, the SSIG 06 475 can only produce 42.8 amps per hour for ten hours or 21.4 amps per hour for 20 hours. These amperage ratings make the Rolls 6CS25P the ideal 6 volt battery for solar system.
Most 6-volt batteries have an amperage rating of 120 to 225 Ah, offering RV owners a wide selection of power units for their needs.
How do you maintain a 6-volt RV battery?
Maintaining a 6-volt battery is not that different from a 12-volt power unit. The following can guide RV owners in keeping their 6-volt batteries in tip-top shape.
- For flooded lead-acid batteries
- Check the water level every 15 to 30 days and top it off with distilled water every two to four weeks.
- Check the state of charge with a refractometer.
- Equalize the battery by controlled-overcharging it every 30 to 90 days.
- For sealed lead-acid batteries
- Determine the state of charge using a multimeter.
- For lithium batteries
- Assess the state of charge using an appropriate battery charge monitoring device.
- For all 6-volt RV batteries
- Check for dirt, dust, fluids, and signs of corrosion.
- Assess the battery cables and corresponding connections for a loose fit, fraying, breakage, and other signs of loss of integrity.
- Clean the battery top using a water and baking soda solution and brush.
- Use a battery clamp and post cleaner to clean the terminals.
- Store batteries in a dry and cool place with adequate protection from the elements.
Is it OK to leave RV plugged in all the time?
Yes, it is OK to leave the RV connected to the batteries all the time, provided it is only for the short-term or during RV operation. Motorhomes use two types of electricity to run various appliances, gadgets, components, and devices. Batteries deliver DC power to fans, lights, radios, and TVs. On the other hand, air conditioners require AC electricity from shore power, which can be converted to DC power and stored in batteries.
Hence, it is unsurprising that many RV owners keep their RVs connected to the battery to operate these appliances.
It is not a good idea to keep the RV connected to the battery for several weeks without using the RV. One can have a top-of-the-line Interstate 6v rv battery, but it will still lose charge over time.
A better option is to fully charge the RV batteries before disconnecting them from the motorhome and storing them in a cool, dry, and well-protected place. Alternatively, RV owners can use a battery tender or a trickle charger to maintain the battery’s charge while plugged into the RV.
How long do 6-volt RV batteries last?
A 6-volt battery for motorhomes should last five to seven years. However, its longevity depends on several factors, such as care and maintenance, usage, ambient temperature, depth of discharge, battery type, and charge-discharge cycles.
For example, an AGM battery might last at least four years, while an ordinary sealed lead-acid battery might only last two years. Lithium-phosphate batteries have a longer lifespan because of their higher charge-discharge cycles (1,500 to 2,000 cycles). On the other hand, SLAs have a discharge cycle of 600 to 700 cycles.
Using RV batteries to operate electric appliances even when not needed can also impact their lifespan. Frequent use hastens the charge-discharge cycle. Discharging the battery below 50% also shortens its lifespan. Overcharging and undercharging RV batteries can cause irreparable damage. With such usage, they require a replacement sooner than one can expect.
It would be best for RV owners to observe a meticulous battery maintenance regimen to get the most value out of their purchase. After all, battery prices are skyrocketing.

A higher Ah rating translates to longer runtimes of appliances and devices. You will be able to use your portable gadgets a lot longer. The battery’s charge also lasts longer than a 12V 100Ah unit.
Six-volt batteries also have larger discharge/recharge capacities than 12V units. They have more charging cycles than your average battery. This type of battery is also less prone to battery memory effect, whereby the unit does not hold a full charge anymore.
If you take good care of your 6-volt battery, you can expect it to continue powering your RV for the next six to eight years. They are more durable and more energy-dense than 12-volt products. These batteries have heavier plates between cells, allowing them to withstand the chemical changes with each charging cycle.
The weight is also another advantage of 6V units over 12V systems. However, you should know that 6V batteries are often taller than their 12V counterparts. They are also quite difficult to source because most retailers carry only 12V units.
Given the advantages of 6V batteries, many RV owners now replace their 12-volt battery systems with a pair of 6-volt units to run their appliances. It is a more cost-effective solution to getting the RVing adventure they need. That is why 6V batteries are better.
How long do 6V RV batteries last?
With proper care, a 6-volt RV battery can last up to eight years. There are some tips you can observe to increase the service life of your battery.
