Is your HP EliteBook Folio 1040 barely holding a charge? This 6-cell replacement battery will bring it back to life! It's compatible with the G0, G1, and G2 models of the EliteBook Folio 1040. The specs are solid: 11.1V, 42Wh capacity, Li-Ion technology - basically what your laptop came with originally. This generic/unbranded battery works with a bunch of part numbers including 722236-1C1, 722297-001, HSTNN-DB5D, and of course BL06XL. The best part? It comes with a crazy good 5-year warranty! That's way longer than most batteries offer. Just be aware of the California Prop 65 warning about chemicals (standard for all batteries). It's brand new in retail packaging, ready to swap out your old, tired battery. Installation is usually pretty easy - just pop off the bottom cover, unplug the old one, and plug in the new. Your laptop will feel like new again with proper battery life. No more scrambling for outlets every hour! Perfect for students, business travelers, or anyone who needs their EliteBook to last through the workday.
