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.

Student Tech Tip: Chromebooks are often left in backpacks or used until they reach 0%. If your Acer Chromebook Spin 11 won’t turn on even when the charger is blue, the AC15A3J battery may have entered a ‘deep discharge’ state. Replacing the internal battery is a cost-effective way to fix power-on issues and avoid buying a whole new laptop.

Frequently Asked Questions

Q: Will this battery fix my Chromebook if it only works when the charger is plugged in?

A: Yes! This is the most common sign of a dead battery. A new AC15A3J will restore your Chromebook’s ability to hold a charge for hours of portable use.

Q: Is this compatible with the “Spin” flip-screen models?

A: Absolutely. This battery is designed for the Spin 11 (CP311) series and is built to handle the constant movement of the 360-degree hinges.

Q: How long is the warranty for school use?

A: We offer a 12-month warranty and a 30-day return policy, ensuring your device remains a reliable tool for the entire school year.
