AutoTrader EV Battery Health Tracker

Autotrader SOH Tracker finds Battery State of Health data on used EV listings so you don't have to dig for it manually. Key Features: Search Badges — Detects SOH percentages and "SOH on Request" mentions in listings, then pins colour-coded badges directly to the search results page. Auto-Tracking — Saves the price, mileage, and SOH of every listing you visit. Alerts you when a price drops or SOH changes between visits. Degradation Analysis — Flags listings where battery health is lower than expected for the car's age and mileage. Stored Locally — All data stays in your browser. Nothing leaves your device.
