97Wh 11.1V Li-ion Battery

This 97Wh lithium-ion battery operates at 11.1V and contains nine cells rated at 7800mAh. It is designed for Dell Latitude E5420, E5430, E5520, E5530, E6420 and E6430 models. The black pack replaces the original M5Y0X, 71R31 and T54FJ units.

Replaces worn original packs

It restores full runtime when the factory battery no longer holds charge or shows reduced capacity. The upgrade is worth it when daily unplugged use drops below acceptable levels. Compatible with both 11.1V and 10.8V system requirements.

Simple slide-in installation

The pack slides into the standard battery bay and locks with the existing latch. No tools or firmware updates are required. The main risk is forcing the connector if alignment is off, which can damage the motherboard header.
