Battery Finder

The R&J Battery Finder is a comprehensive tool designed to help you quickly find the right battery for your vehicle or equipment. Built from over 30 years of industry experience, the R&J Battery Finder features up to date and accurate fitment data for thousands of vehicles. Results will include recommended part numbers from trusted brands like Delkor, ACDelco, Predator, Hardcore, and Motobatt (for motorcycles).

R&J Batteries continues to improve its Battery Finder; it now has 4 key functions: 

1.        Search by Vehicle

Select your application type (Car & Light Commercial, Truck & Heavy Commercial or Motorbike & Powersports) and enter your vehicle's make, model and year. The tool will then generate a list of battery options suited to your vehicle.

2.        Search by Vehicle Registration Number (REGO)

Enter your vehicle’s registration number to instantly find compatible battery options. This function quickly finds your vehicle details and matches them to the correct battery. This leaves little room for error and will show you various options to meet your vehicle’s specific needs.

3.        Search by Part Number

If you already know your battery part number or case size, simply enter it to view its specifications and find compatible or alternative R&J Batteries products.

4.        Search by Attribute

If you know what you need from your battery but don’t know the part number, try Search by Attribute. This tool lets you search and filter by battery type, CCA, Ah, dimensions or weight to find a battery that fits your specific requirements.

Whichever Battery Finder function you use, you’ll also gain the benefit of a live product data sheet. From the battery results, select your desired battery to view the specification page. This can then be exported to PDF as a product data sheet with the most up to date information for that product.

Users that search with the Vehicle or REGO lookup for automotive vehicles will also see an additional fitment note specific to their search. This will identify any key things to look out for when fitting a battery in that selected vehicle.

Auxiliary Battery System Calculator

For those running 12V auxiliary power systems in caravans, campers, or work vehicles, the Auxiliary Battery System Calculator is a must use tool. This calculator can be used to estimate your system's usable capacity, daily power consumption, and expected run time.

Step 1: Input the power rating (watts) and daily usage hours of each device you'll be running. If you don't know the power rating, you can multiply the maximum current draw (in Amps) by 12V to calculate it. 

Step 2: Enter your battery's capacity, how many batteries you have, and your system's ideal Depth of Discharge (DoD)*. Once complete, the calculator provides a clear summary of your available power and system performance.

*Lead Acid batteries can only safely discharge to 50% of their capacity; however, lithium (LiFePO₄) batteries can discharge up to 100% of their rated capacity.
