The power you need

Increase your mobile productivity by taking along a fresh, fully charged Oncore battery. A ready spare can be easily swapped in to keep the power flowing, making unplugged all-day computing a reality. For extra convenience and mobility, enjoy a backup battery at home or work. Or keep one in your carrying case to double your battery life when traveling.

An Oncore battery also makes a great replacement for your aging original. For most models, our high capacity Lithium Ion (LiIon) technology gives this battery a longer life and lighter weight. And each Oncore battery is designed, tested and certified to support your specific notebook and features the same quality and reliability as the original battery that came with your system.
