Understanding the Highlander Hybrid Battery
The Toyota Highlander Hybrid uses a nickel-metal hydride (NiMH) battery pack to store and supply electrical energy. The battery pack is located in the rear cargo area, beneath the floor. It consists of multiple modules, each containing a series of individual cells. The battery pack operates at a high voltage and should be handled with care.
Regular Inspection and Cleaning
Regularly inspect the battery pack for any signs of damage, such as leaks or corrosion. If you notice any issues, consult a professional technician for further evaluation and repair. Keep the battery terminals clean and free from corrosion. Use a mixture of baking soda and water to clean the terminals and remove any corrosion. Make sure to disconnect the battery before cleaning, following the proper safety procedures outlined in the vehicle manual.
Maintaining Optimal Battery Performance
Avoid prolonged periods of inactivity as it can drain the battery. If you won't be using the vehicle for an extended period, consider using a battery maintainer to keep the charge level stable. Drive the vehicle regularly to keep the battery charged. Toyota recommends driving at least 20 minutes to ensure proper charging of the battery. Avoid excessive use of electrical accessories when the engine is off to prevent draining the battery excessively.
Extreme Temperature Considerations
Extreme temperatures can affect the performance and lifespan of the battery. In very cold conditions, the battery may experience reduced capacity and slower charging. Consider using a battery blanket or parking the vehicle in a heated garage during extreme cold weather. In extremely hot conditions, take measures to protect the battery from excessive heat and direct sunlight. Parking in shaded areas and using sunshades can help minimize heat exposure.
