Tesla Quietly Removes Battery Health Test: What You Need to Know

Hey everyone, DennisCW here! If you're a Tesla owner or enthusiast like me, you've probably heard the buzz about Tesla's latest software update. In this post, I'm diving into a recent change that's got the community talking: Tesla has quietly removed the battery health test feature from vehicles. This was covered in one of my recent videos, and I wanted to break it down here for you in more detail. Let's explore what this means, why it might have happened, and some alternatives for checking your battery's health. Plus, I'll share my top recommendation for Tesla accessories at the end.

The Disappearing Battery Health Test

In the latest software update, version 2025.26, Tesla has removed the option for owners to run a battery health test directly from their vehicles. Previously, you could access this through the controls > service > service mode menu on some models. But now, it's gone. The Tesla app has even posted about this change, confirming that self-testing is no longer available.

Why the removal? It's speculative, but it could be to prevent abuse of the feature. The battery health test takes an incredibly long time to complete—sometimes hours—which might tie up the vehicle unnecessarily. I chatted with my friend Chip, who runs a dealership specializing in used Teslas, and he mentioned it's often not worth the hassle. Instead, he suggests a simpler approach: check your current battery percentage, note the estimated range, and do some quick math to gauge degradation.

Another theory is that Tesla wants to reserve this diagnostic tool for service centers only. That way, professionals can handle it accurately without owners potentially misinterpreting results. Remember, no one has a definitive benchmark for what constitutes "good" battery health—it's all relative.

Does This Matter for Tesla Owners?

Most Teslas come with a solid battery warranty: 8 years or 120,000 miles (depending on the model), whichever comes first. If you're buying new, this should give you peace of mind. Personally, I don't see myself keeping a Tesla long enough to hit that warranty limit, but it's reassuring to know it's there.

That said, if you're in the market for a used Tesla, this change might make things a bit trickier. Without the self-test, you'll rely more on range estimates, third-party tools, or a professional inspection. Have you ever run a battery health test on your own Tesla? Do you miss the feature, or is it no big deal? Let me know in the comments—I'd love to hear your thoughts!

Quick Tip: Don't Forget the Essentials

While we're on the topic of Tesla ownership, let's talk about something every owner needs: all-weather floor mats. If you're picking up a new Tesla, it might not come with them, so you'll want to invest in a quality set. After trying out tons of options—like 3D Maxpider, Tesmanian, and various Amazon brands—my absolute favorite is from 3W Liners.

I've got them in my Model X, Model 3, Model Y, and even my Cybertruck. They look better than OEM in my opinion, come with a lifetime warranty, and provide excellent protection. The best part?
