Hybrid Battery Parts Guide: Harnesses, Bus Bars & Cables

Find hybrid battery repair parts by the component you need: replacement blades, equalizer cables, wiring harnesses, bus bars and nuts. These are service parts, not complete hybrid battery packs or 12V auxiliary batteries.

Start with the right match

Start with your vehicle year, make and model. Confirm the battery configuration and product instructions before ordering. Ask us to match your part.

Replacement blades and equalizer cables

Match the installed battery revision, blade specification, connector and block configuration. Vehicle year and model alone do not establish compatibility.

Wire harnesses and harness kits

Compare the existing part number and connector layout. Similar product titles do not mean the assemblies are interchangeable. Review the individual listing for kit contents.

Bus bars and nuts

Match the battery chemistry, module or block count, and hardware configuration. A sodium-ion conversion and an original battery may require different hardware for the same vehicle.

Need help choosing?

Send the product listing and your model year to our support team. A shared vehicle name or matching year range is not enough to confirm every component. Hybrid battery service should be performed by a qualified technician following the applicable manufacturer instructions.
