Choose by requirement

Match battery duty, fit and charging

A battery must suit both the load profile and the vehicle or system that will charge and house it.

Choose the dutySeparate starting, dual-purpose and deep-cycle needs before comparing capacity or cranking ratings.
Confirm physical fitCheck case dimensions, terminal layout, hold-down, weight, ventilation and installation orientation.
Verify chargingMatch the battery type to charger profiles, voltage settings, current limits and the broader bank configuration.

Quick usable-runtime check

Estimate usable battery runtime

Enter bank capacity, voltage, chemistry and average load. The estimate applies a simple usable-capacity allowance for the selected chemistry.

Absolutely stellar service from Cameron at Solar 4 RVs. Initially had him quote up a solar system for my campervan back in June 2024 and then when I was ready to purchase in November 2024 he was able to give me the best prices for every product and so I went ahead with the order.

Also gave me some tips to commission the system once I installed the products. Stoked on the Victron gear. Thanks guys!

Purchased a 12v/15a battery charger in 2023. Had issues with it today (2025). Called their info number and explained. Instantly agreed to accept it as a warranty issue and dispatched a replacement without any problems. Extremely quick service and item dispatched express courier that same day. Outstanding customer service. Thank you.

Purchased a literal boat load of electronics from them for our vessel. It all works great and they did an amazing job setting up the panel. We have had the gear a few years now and still reach out when we need help. Great customer service!

The Century Batteries Difference




Since 1928, Century Batteries has been designing and manufacturing our iconic blue and yellow batteries right here in Australia. Over the years, we have developed the manufacturing expertise and technical know-how to develop a range of batteries perfectly suited to our unique country. 

Our range of sealed maintenance free batteries are the result of over 90 years of Australian innovation and refinement. We’re rather proud of them, because they’re the best batteries we’ve ever built.

A perfect balance between cranking performance and life, they incorporate an advanced labyrinth lid system and heat sealed double lid technology to reduce water loss whilst increased electrolyte levels, cutting edge plate designs and specialist paste formulations combine to deliver superior cranking performance, corrosion resistance and heat tolerance.


1. ROTARY PLATES

• Specialist advanced plate design provides longer service life and resistance to corrosion and material shedding.

• Lower internal resistance promoting higher CCA and improved vibration resistance.



2.ENHANCED PLATE PASTE

• Reduces water loss and improves charge acceptance for superior performance and cycle life.


3. SEPARATORS

• High Porosity Polyethylene Envelope (PE) separator improves puncture resistance and durability.

• Improves electrolyte dispersion for enhanced performance and power.


4. FLAME ARRESTOR

• The integrated flame arrestor in the central venting system protects the battery from explosion due to ex

5. MUD RACK

• Improves plate support, vibration resistance and isolates paste deposits to prevent short circuits.


6. POLYPROPYLENE CASE

• Reinforced design provides durability to withstand shock and vibration.


7. CARRY HANDLE

• Ergonomic design provides a thicker grooved carry handle to improve comfort.

• Utilises fully constrained safety design with pivot pin mould



8. STATE OF CHARGE INDICATOR

• For on the spot diagnosis of battery condition.



9. CAST ON STRAP

• Thicker cast on strap ensures durability and lower electrical resistance to promote longer life.



10. LABYRINTH LID TECHNOLOGY

• Provides spill proof protection up to 90°.

• Reduced water loss.




 



 



 




Before you choose

Century battery questions

Battery duty, chemistry, physical fit, terminal layout and the available charging system must all suit the application.

How do I choose the right Century product?

Start with the job the product must do, then compare voltage, current, capacity, dimensions, interfaces and environmental limits for each model. Use the current product page and manufacturer documentation for final selection.

Will Century products work with my existing system?

Compatibility depends on the exact model and surrounding equipment. Confirm system voltage, connector or communications standards, charge or load limits, physical fit and every required companion component.

What installation details should I check before ordering?

Check mounting orientation, clearances, cable routes, conductor and terminal sizes, protection, ventilation, environmental exposure, service access and any work that requires an appropriately qualified installer.

Where should I confirm the final technical specifications?

Use the exact product page, current datasheet, installation manual and any model-specific certificates or compatibility lists. Do not rely on another product in the same family because ratings and inclusions can differ.

Do all Century products have the same warranty?

No. Warranty periods, exclusions and claim requirements can vary by product family and application. Check the current warranty information for the exact product before purchase.

Can Solar 4 RVs check the complete combination?

Yes. Share the application, system voltage, existing equipment, maximum loads, charging sources, available space and the products being considered. The team can help identify the specifications and companion parts that need checking.
