Replacement Battery for Lenovo Yoga 710 Series

This 7.6V lithium-ion battery replaces part numbers 5B10K90778 and 5B10K90802 in Lenovo Yoga 710-14IKB, 710-14ISK, 710-15IKB and 710-15ISK models. It supplies 60Wh and 3912mAh from four cells and is sold new from the manufacturer. The smart chip manages charge reporting and cell balancing.

What the Smart Chip Changes

The onboard circuit board authenticates the pack with the notebook firmware so the operating system reports accurate capacity and health data. Without this handshake the laptop may refuse to charge or show an incorrect percentage. The chip also balances the four cells during each cycle to extend usable lifespan.

Limits of the 7.6V Li-ion Interface

The pack delivers a fixed 7.6V nominal output; it cannot adapt to systems that require a different voltage rail. Capacity is limited to 60Wh, so runtime on larger 15-inch configurations will be shorter than on the 14-inch variants. The connector is keyed for the Yoga 710 family and will not mate with other Lenovo chassis. Users needing higher capacity or a different form factor must select another part.

Questions about this item

How many charge cycles can the 7.6V 60Wh 3912mAh Li-ion pack deliver before it needs replacing?

The 4-cell Li-ion battery is rated for hundreds of full charge cycles; capacity will gradually decline and replacement is typically considered when run-time drops below 80 percent of the original 60Wh.

What limits continuous run-time on the 7.6V 60Wh pack during a full work day?

The 60Wh capacity sets the energy ceiling; under sustained load the pack will deplete in proportion to the laptop's power draw, so run-time varies with screen brightness, CPU load and connected peripherals.

Does the 7.6V 60Wh battery run hot or make noise when the Yoga 710 is used all day?

The battery itself has no moving parts and generates only modest heat during charge or discharge; any fan noise or warmth comes from the laptop's cooling system, not the pack.
