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.

Usage & Maintenance Guide

L-Series High Capacity: This CF-VZSU90JS is the “Large” capacity version (L). If your original battery was the thinner “Small” version, this model will provide significantly longer runtime but may have a slightly different physical profile.
Panasonic Eco Mode: Like most Let’s note models, your LX device may have “Battery Eco Mode” enabled in the BIOS or Dashboard, which limits charging to 80% to extend cell life. This is a software feature and not a hardware defect.
Secure Locking: Ensure both the main latch and the secondary lock on the battery bay are engaged to prevent power interruption during movement.

Frequently Asked Questions

Q: Can I use this battery on a CF-LX6 if my original was CF-VZSU0CJS?

A: Yes. The VZSU90 series and VZSU0C series are fully interchangeable across the LX3/4/5/6 chassis generations.

Q: Is this 74Wh version much heavier than the standard battery?

A: The 6-cell (L) version is designed for maximum endurance. While slightly heavier than the 3-cell (S) version, it is the preferred choice for professional travelers who prioritize full-day battery life.
