Reliable RV Power Starts With the Right Battery System
Your RV batteries power far more than lights—they support water pumps, appliances, leveling systems, slide-outs, inverters, and many of the comforts that make RV travel enjoyable.
At California RV Specialists, we offer battery testing, battery replacement, battery upgrades, installation support, charging system guidance, and battery maintenance products to help keep your RV powered and dependable.
As an Interstate Battery dealer, we offer quality starting and deep-cycle battery options and can help you select the right battery solution for your RV and camping style.
Whether you need replacement batteries, improved off-grid capacity, or battery maintenance tools and supplies, we’re here to help.
Call 209-263-7040 to schedule battery testing or replacement.

CONSIDERING A BATTERY UPGRADE?
Upgrade Your RV Power System
Depending on your needs, upgrading batteries may improve:
- Dry camping capability
- Reserve power
- Inverter performance
- Solar system performance
- Overall power independence
Ask us about available battery upgrade options, including higher-capacity systems and lithium upgrade paths.
BATTERY TOOLS & MAINTENANCE PRODUCTS IN STOCK
We carry helpful battery maintenance products and tools such as:
- Battery testers
- Battery lifting straps
- Battery fillers
- Terminal maintenance supplies
- Battery care accessories
Routine maintenance items can help support longer battery life and better performance.
DON’T FORGET BATTERY TERMINAL MAINTENANCE
Battery terminals and cable connections should be periodically inspected for:
- Corrosion
- Loose connections
- Resistance issues
- Heat damage
- Voltage loss
A poor connection can mimic a bad battery.
WHY CONSIDER TWO 6-VOLT BATTERIES?
Many RV owners choose paired 6-volt batteries for:
- Increased amp-hour capacity
- Longer cycle life
- Better deep-cycle performance
- Improved off-grid endurance
If you’re considering upgrading, we can help evaluate whether that makes sense for your RV.
MORE THAN BATTERIES — WE CAN HELP WITH THE SYSTEM
Sometimes the battery isn’t the only issue.
Charging concerns may involve:
- Converter performance
- Charging profiles
- Solar charging
- Parasitic battery draw
- Battery disconnect concerns
If something doesn’t seem right, we can help point you in the right direction.

Why Upgrade To Two 6 Volts
- 6V batteries have thicker plates, meaning they can be charged and discharged more frequently.
- They have a longer lifespan.
- Because they have half the number of plates in their cells, 6V batteries weigh less.
- When wired in series, you can double the number of volts with smaller, lighter batteries in your battery compartment.
- 6V batteries typically have larger Ah capacities.
Battery Core Required & California State Battery Fee
6 Volt & Group 31 $30.00 Per Battery
Group 24/27/65 $20.00 Per Battery
