The 97 Wh Battery is a 9‑cell Lithium‑Ion replacement battery made to power certain Dell Latitude laptops. It stores a relatively large amount of energy — 97 watt‑hours (Wh) — which means it can keep your laptop running longer between charges than many standard batteries. This makes it useful for things like travel, school, work, and long periods away from an outlet.
