Overview

100% compatible replacement with HP batteries

Specifically designed to fit your laptop. See the full compatibilities list.

Guaranteed 4400mAh capacity

Unlike many competitors, our battery capacities are true, real and guaranteed. This Lithium Ion battery is 4400mAh and offers long runtimes with fewer charging breaks - exactly as advertised.

High-performance 10.8V - 11.1V HSTNN-IB51 battery

Our long-life replacement laptop batteries deliver consistently high performance that matches or exceeds that of your computer’s original battery - all for a high number of charging cycles.

Superior quality and safety standards

Battery specialists since 2004, all our replacement batteries undergo strict, rigorous testing to fully comply with the highest EU standards and beyond - that’s why they come with a 3-year guarantee.

The sustainable choice

Replace the battery, not your device. It’s the smarter, cheaper, eco-friendlier choice, saving you money while cutting your environmental footprint through recycling.

Please Note: >> A replacement lithium-ion battery with a higher capacity (1000mAh or more) will protrude slightly at the bottom or rear but will still be suitable to use, as our replacement battery has been designed to be compatible with the battery compartment in your laptop.

Choose subtel and never compromise on quality. Order now!
