Questions about this item

Does the package include the battery only, or are tools and screws supplied as well?

The box contains the CS03XL replacement battery. Installation hardware such as screwdrivers or retaining screws is not included and must be sourced separately.

How do I confirm this CS03XL unit matches the part number printed on my original battery?

Compare the label on your existing pack with the compatible list: 800231-141, 800513-001, CS03XL, T7B32AA, HSTNN-I33C-4, HSTNN-I33C-5, HSTNN-I41C-4, HSTNN-I41C-5 or HSTNN-IB6Y.

What does the 124 percent OEM compatible claim mean for daily run-time on my EliteBook 840 G3?

The 124 percent figure indicates the cell capacity exceeds the original factory specification, so you should see noticeably longer battery life under the same workload.
