The honest number for your battery. Real capacity. Range over time. How you compare. Battery Health for Tesla shows you what the official Tesla app doesn't - the actual numbers behind your battery, on a clean dashboard you can check in seconds. THREE VIEWS, ONE STORY YOUR BATTERY TELLS • Health - Real usable capacity in kWh, charge cycles, and a verdict (Excellent, Normal, Below Average) anchored to the warranty thresholds for your model and year. No vague percentage. Just the honest number. • Range - Watch your maximum range plotted from the moment you connect. Pinch the chart to scrub through every reading and see the trend, not just whatever the dash showed yesterday. • Fleet - See where your battery sits against every similar Tesla in the TezLab fleet - same model, same year, same trim. Top of the pack, in the middle, or somewhere else? Find out. SHARE THE NUMBERS Battery health, range trend, or fleet ranking - send any of them to other Tesla drivers in one tap. MONITOR ALL YOUR TESLAS, AUTOMATICALLY Connect more than one vehicle and we'll keep an eye on each one. Readings refresh on their own, in the background, as your car checks in - no syncs, no manual refreshes, no long-running tests. PRIVACY-FIRST BY DESIGN • Battery data only. Your car streams battery updates - and only battery updates - on its own schedule through Tesla Fleet Telemetry. We never poll, wake, or send commands. • Anonymized comparison. Your VIN never shows up in anyone else's view of their own battery. • You own the connection. Sign out from the app any time, or revoke access directly from your Tesla account. BUY IT ONCE, KEEP IT FOREVER No subscriptions. No monthly fees. The same purchase covers your next Tesla too. What's included: • Real usable capacity in kWh • Range over time • Comparison vs. similar Teslas • Charge cycles + verdict • Multi-vehicle monitoring • Share with other drivers SUPPORTED VEHICLES All Model 3, Model Y, and Cybertruck.

Great for those that need the battery feature only. Know those that want to buy a Tesla and check the battery, perfect for that! ### 5/5 — Perfect *2026-08-06* New to Tesla, exactly what I was looking for. ### 1/5 — Does not work. Waste of money *2026-08-04* It wont pair with your car after it collects all your information. Waste of money. **Developer response:** Sorry to hear you’re having trouble! If the car won’t connect, there’s definitely a reason and we can help you sort it out. Please contact support@tezlabapp.com from the email address on your account and we’ll look into it and help you get up and running as quickly as possible. ### 4/5 — Unable To Connect But Fixed / Good Option *2026-07-09* Unable to connect but got support. ### 5/5 — Very solid! *2026-07-08* Perfect.

Was easy to connect and gave me the battery numbers. The trend info is really cool Great value. ### 1/5 — Connection issue *2026-06-16* I have TezLab and works fine. This one cannot connect to my Tesla account. Sort this out please **Developer response:** Sorry to hear you’re having trouble!

Please add widgets though for home screen and lock screen. ### 5/5 — Great / simple *2026-06-03* Clearly the developers put a lot of time into this. Exactly what I was looking for. Would recommend. ### 3/5 — Simple but not fully accurate *2026-05-23* Service response good. Picked wrong kWh total for MY. Don’t know if I believe the reports it states on fleet numbers. Good for general info. **Developer response:** Hi there - In response to you letting us know that it picked the wrong “When New” capacity for your vehicle, we undertook a fleet wide review to catch any unintended misclassifications, and any vehicles that were put into an incorrect bucket have been corrected. You can also override the “When New” pack capacity from the main screen if you wish. We apologize for any inconvenience. If we can be of any further assistance, don’t hesitate to contact us at support@tezlabapp.com ## Frequently asked questions about Battery Health ### What is Battery Health for Tesla?
