High-performance 10.8V - 11.1V 42T4835 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.
