Important Shipping Notice (Chinese New Year 2026 - Batteries)
During the Chinese New Year 2026 holiday period, laptop battery orders may take longer than usual to deliver. This delay is mainly caused by battery sourcing (most laptop batteries are manufactured in China) and holiday logistics congestion.

Estimated Battery Delivery Time
Please allow up to 30 days for delivery during this period.

If You Need a Battery ASAP
We completely understand that a working laptop is time-sensitive. If you need a battery urgently, please order with caution. For the fastest solution, you may prefer a local seller or another supplier that is not impacted during the holiday season. While we are sorry we may not be the quickest option for urgent cases, we will be genuinely happy if you can get your problem solved sooner.

If You are Not in a Hurry
If you can wait, you can place your order with confidence. It is very common to keep using a laptop with reduced battery runtime by plugging it in when needed. We will ship as soon as sourcing and logistics allow, keep your order moving, and deliver a high-quality, reliable battery that fits your device properly.

Thank you for your understanding and support.

Frequently Asked Questions

Q: Will this fit my Medion Akoya E17201?

A: Yes, the E17201 is a primary model for this 45mm version. Please check your original battery to confirm the cable length is approximately 4.5cm.

Q: Can I use a 25mm cable battery instead?

A: No. If your motherboard requires a 45mm reach, the 25mm version will be too short to connect to the power port.
