Authored by: Will Peters, Certified Electric Bike Technician & Micro-Mobility Specialist
Picture this: you're cruising through Atlanta's BeltLine on your trusty e-bike or zipping past traffic on your e-scooter. Suddenly, your ride slows to a crawl, or worse, stops completely. The culprit? A misbehaving battery. Fear not, fellow riders! At eStar Rides, we’ve seen it all, and I’m here to share the most common e-bike and e-scooter battery issues—and how to keep your battery (and your ride) in tip-top shape.
- Reduced Capacity: When Your Battery Loses Its Mojo
- What’s Happening? Over time, your battery’s cells naturally degrade, leading to a shorter range.
- Symptoms: Your once-reliable 50-mile range now feels like a frustrating 15-mile crawl.
- The Fix: Adopt good charging habits:
- Charge after every use, but don’t leave it plugged in overnight.
- Store your battery at 40%-60% charge if not riding for a while.
- Avoid extreme temperatures (more on that below!).
- Learn more about battery maintenance tips.
- It Won’t Charge (Ugh, Why?)
- What’s Happening? A faulty charger, damaged port, or internal battery issues could be to blame.
- Symptoms: No charging light, no power—no fun.
- The Fix:
- Double-check connections and ensure the charger is working.
- Use only the manufacturer-recommended charger.
