Buyers with laptops outside the listed Latitude and Precision series should look elsewhere, as fit and connector alignment are model-specific. The pack is not designed for ultrabooks or tablets that require a different form factor or voltage. Users who need higher capacity than 4400 mAh or a different cell chemistry will not be served by this unit. Always verify the original battery part number and output voltage before ordering.

4400 mAh capacity for typical office workloads

The 49 Wh rating supports several hours of general productivity, web browsing and document editing on compatible systems. Runtime decreases under sustained heavy loads such as rendering, compilation or gaming, where the pack will deplete more quickly. The 6-cell configuration provides a balance of capacity and weight for the supported chassis. For all-day mobile use without access to mains power, a higher-capacity alternative would be required.
