Direct Replacement Battery

KingSener B8000 L13D3E31 is a 3.75V 9000mAh Li-ion pack built for Lenovo Yoga 10 inch tablets including B8000 and B8080 series. It matches the original dimensions so installation requires no modification. The pack uses Korean cells tested before shipment.

Questions about this item

How often should I cycle the KingSener B8000 battery to maintain its 9000mAh capacity?

Fully charge and discharge from low current two or three times initially, then repeat periodically to keep the cells balanced.

What is the first limit reached when the 3.75V 33.8Wh pack runs continuously?

The 9000mAh capacity depletes, ending runtime before any thermal or voltage threshold is hit.

Does the Li-ion pack generate noticeable heat during all-day use in a Lenovo Yoga tablet?

High-quality Korean cells and the integrated PCB keep temperature low under normal load.
