Replacement Battery for LG Gram 16Z90R

This 7.76V 90Wh lithium-ion battery replaces part numbers LBY122CM and EAC6479830 in compatible LG Gram laptops. It fits the 16Z90R, 16Z90R-A, 16Z90R-G, 16Z90R-K, 17Z90Q, 17Z90Q-G, 17Z90Q-K and 17Z90Q-R model families. The black unit is supplied new with a 12 month warranty.

Upgrading from a Depleted Original Pack

When the factory battery no longer holds a useful charge, this direct replacement restores the original runtime without modification. The swap is worth it when the laptop shuts down unexpectedly, reports a capacity warning or fails to reach a full charge. It matches the 7.76V voltage and 90Wh capacity of the original specification.

Installation in Compatible LG Gram Chassis

The battery slots into the internal bay of the listed Gram 16 and 17 inch models using the existing connector and screw points. No adapter cables or firmware updates are required. It frees the user from tethered outlet charging and restores full mobile operation for the supported part numbers.

Questions about this item

Will the LBY122CM battery fit inside my LG Gram 16Z90R without modification?

This pack replaces part numbers LBY122CM and EAC6479830 and is listed for Gram 16Z90R, 16Z90R-A, 16Z90R-G and 16Z90R-K chassis.

Which screw or latch do I release first when swapping the battery in a Gram 17Z90Q?

Remove the bottom case screws, disconnect the old pack connector from the motherboard, then lift the battery out; the connector is keyed so it only seats one way.

When will the 90 Wh lithium-ion cell need replacing?

The supplier provides a 12-month warranty; after that period the pack should be replaced once runtime no longer meets your needs.
