Battery Health - For Rivian

The honest number for your battery. Real capacity. Range over time. How you compare.

Battery Health for Rivian shows you what the official Rivian 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 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. Drag across the chart to scrub through every reading, or tap zoom to close in on the trend - not just whatever the dash showed yesterday.

• Fleet - See where your battery sits against every similar Rivian 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 Rivian drivers in one tap.

MONITOR ALL YOUR RIVIANS, 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 • 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 to disconnect.
