Match the connector layout, existing part number and installed battery configuration. Similar vehicle years or photos do not establish interchangeability.

Installation and selection

Hybrid batteries contain high voltage. Have a qualified technician follow the vehicle service manual and the battery manufacturer’s instructions, using the required protective equipment.

Wiring note: wire colors do not match the factory wiring diagram. Install the harness in the existing housing in the sequence specified on the packaging label or manufacturer’s product photos. These are battery-service components; a complete hybrid battery pack is not included.

Contact My New Battery with your vehicle year, model, installed battery configuration and existing part details before ordering if the match is uncertain.

For an included orange housing, see the Gen 2 harness assembly. Harness-only option also available.

Warranty options and support

Eligible hybrid battery packs offer a Standard 2-Year or optional Platinum 10-Year warranty, both with unlimited miles. Coverage is for the original purchaser and begins on delivery. Select the plan offered for this product.

Read the full hybrid battery warranty options, eligibility and exclusions. For other products, consult the warranty policy, product listing and your order confirmation.
