T4U for Tesla vs YouMonitor

Finally know the real condition of your Tesla's battery. Not the charge percentage. Not a figure inferred from displayed range. State of Health — how much capacity your pack has left compared to the day it left the factory. T4U is built by MyBatteryHealth, Europe's reference network for electric vehicle battery diagnostics. Over 70,000 batteries certified. MEASURED, NOT ESTIMATED Your car continuously reports the energy actually left in its pack. T4U reads that figure and derives your battery health from it. The vehicle's own computer does the measuring; we only translate. This works with the car parked and locked. You get a fresh reading every day without anything ever disturbing your vehicle. WHAT YOU GET - State of Health as a percentage, with an MBH grade from A to E - Current pack capacity in kWh, against its original capacity - Real-world range, calculated from your own data - Twelve-month degradation curve - Manufacturer warranty tracking: years, mileage, minimum State of Health - Battery chemistry, cell supplier, recommended charge limits - Maximum charging power and Supercharger compatibility - Live charge level, range and lock status - Home screen widget, current even while the car sleeps ADVANCED PACK DIAGNOSTICS Where a consumer app stops at a percentage, T4U goes down to cell level: - Voltage spread between the highest and lowest brick groups — the indicator that degrades before you lose any range - Thermal spread between modules, and the position of the hottest sensor - Internal pack resistance, measured while driving - Open-circuit voltage, and voltage per cell - Real cycle count, derived from lifetime energy consumed Each of these identifies a weak point by its number inside the pack. That is what lets you document a fault with a professional. YOUR BATTERY CARD Generate your score and share it. A social-ready card carrying your grade, your battery health, your mileage and the MyBatteryHealth certification. THE OFFICIAL MBH REPORT Issue a digitally signed battery health certificate, verifiable by QR code. A document recognised by automotive professionals, leasing companies and used car buyers — and the strongest argument you have when defending your Tesla's price at resale. WHAT T4U DOES NOT DO T4U has no permission to command your vehicle, and never asks for one. It will not wake it, unlock it or move it. No location data is collected. Distance is reconstructed from the odometer. Every figure on screen states where it came from and when it was measured. A number you cannot explain is worth nothing. T4U PREMIUM The subscription unlocks full cell-level diagnostics, weak point localisation inside the pack, twelve months of history, driving performance and unlimited sharing of your battery card. €1.99 per month or €14.99 per year.
