Stop/Start Battery Caution

Some 2017-2019 Toyota Highlander vehicles are equipped with an engine Stop & Start system. If the battery is to be replaced, it is important to use P/N 28800-31550.

There is no recommended Truestart battery that is applicable for Stop & Start Highlanders. The Stop & Start equipped battery is specially designed for deep discharges and it is of a design called enhanced flooded battery (EFB). Characteristics of EFB type batteries are the ability to quickly discharge and recharge.

When testing batteries for Stop & Start equipped Highlanders, use the battery type “enhanced flooded” (EFB) when using the battery tester.

If you are not sure if the Highlander is equipped with Stop & Start functionality, there are several ways to identify them. Stop & Start equipped vehicles have a Stop & Start indicator light and a button on the dash to turn the system off temporarily. Stop & Start is standard equipment on V6 Highlander LE Plus, XLE, SE and Limited models.

You can also identify the correct battery by looking at the battery label, which should have the part number 28800-31550. The battery manufacturer “GS Yuasa” can be seen on the front of the battery in raised letters and on the battery label. It also has screw type vent caps, not press-in vent caps.
