FAQ — Medion A31-M15 45mm Line 42Wh Battery

If your laptop shows multiple issues below, your battery may be failing. Tick the boxes that match your experience:













Yes — most likely. For 100% certainty, check either your laptop model or your original battery part number.

Free Compatibility Check: At checkout, add your model or part number in the order notes (or email us after ordering). We’ll verify before shipping. If something doesn’t match, we’ll correct the order so you get the right battery the first time.

  • On the laptop: Label/sticker on the underside or side (look for “Model”, “P/N”).
  • On the battery: Printed part number on the battery label (if removable).

30-day easy returns and a 12-month warranty against defects.

Typical install takes 15–25 minutes. A basic tool kit is included. Power off, unplug the charger, and handle the battery by the edges only.

We accept major credit cards and PayPal via secure checkout.

Not always. Fast draining can be caused by background apps, settings, or an old battery. If your battery lasts less than 30–60 minutes unplugged, it’s usually time to replace it.

Yes, in most cases. This is a common sign of a worn-out battery. A new compatible battery should restore normal portable use.

Many laptops limit charging to 80–95% to extend battery life. If it’s stuck much lower, the battery may be failing and should be replaced.

Check seating and contacts first. If the issue continues, the battery is likely faulty and replacing it will usually solve the problem.

Yes, but long-term constant charging can reduce battery lifespan. Unplug and run on battery once or twice a week to keep it healthy.

Most laptop batteries last about 2–4 years or 300–500 charge cycles, depending on usage and care.
