LeafHacker is an Android app developed by LeafHacker, available for free in the Travel & Navigation category. This app provides users with the ability to register their battery ID after replacing the HV-Battery, LBC, or VCM in their vehicles. Additionally, LeafHacker allows users to change the quick and low charges after replacing the battery, LBC, or VCM.

One of the notable features of LeafHacker is its ability to correct the odometer mileage in ZE0/AZE0 models after the instrument cluster has been replaced. This can be particularly useful for ensuring accurate mileage records. Furthermore, the app also offers the functionality to change the odometer language in ZE0/AZE0 models.

It is important to note that while LeafHacker is a free app, all of its functions require payment. Users will need to make in-app purchases to access the battery registration, charge adjustment, and odometer correction features.
