The WRONG Battery Was Installed?! | BMW Motorcycle Battery Mistake 🔋

Описание: In this video, I replace a very cheap motorcycle battery with a premium Yuasa battery — and I show you exactly why it had to go.

The old battery looked fine from the outside, but testing told a different story:
Internal resistance: 15 milliohms
State of Health (SOH): only 67%

That’s a recipe for:
❌ Hard starting
❌ Voltage drops
❌ Electronics acting strange
❌ Getting stranded

I also explain why it’s critical to fully charge a NEW battery before installing it.
Many riders skip this step — and that’s how a “new” battery gets damaged before it even starts its life.

In this video you’ll learn:
✔️ How to diagnose a bad motorcycle battery
✔️ What internal resistance really means (simple explanation)
✔️ Why cheap batteries fail early
✔️ Why Yuasa batteries cost more — and why it’s worth it
✔️ The correct first charge procedure before installation

💡 Doing this job yourself is easy, and it saves money — that’s what this channel is all about.
