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.

Why Upgrade to the 72Wh 68++?

Triple the Capacity: Offers 3x the runtime compared to the standard 3-cell (24Wh) external battery.
Ergonomic Tilt: The extended 6-cell design protrudes from the bottom, creating a natural typing incline and enhancing thermal dissipation.
Power Bridge Ready: Hot-swap this battery without shutting down your OS (works in conjunction with your laptop’s internal battery).
Premium Safety Standards: Grade-A cells and integrated BMS provide multi-layer protection against over-current and overheating.

Frequently Asked Questions

Q: Will this battery stick out from the bottom?

A: Yes. As an extended 6-cell battery, it is larger than the standard 3-cell battery. It will lift the back of your laptop slightly, which is a popular feature for better cooling and typing comfort.

Q: Will this fit my T460s or T470s?

A: No. The “s” slim models (like T460s/T470s) use specific internal batteries and do not have an external battery slot. This is for the standard T460, X270, and similar models.
