Dell Latitude 5320 7320 7420 7520 replacement

This 15.2V 63Wh lithium-ion polymer battery replaces the original power pack in Dell Latitude 5320, 7320, 7420 and 7520 series laptops, including the 2-in-1 variants. It is built for professionals who need a direct swap to restore full mobile runtime without adapter changes.

Four-cell pack with built-in circuit protection

The battery uses Grade A cells rated for 500-plus recharge cycles and integrates a smart control chip that manages charging current and discharge pacing. Multi-protect circuitry guards against overcharge, over-discharge and short circuits, reducing the risk of leakage and keeping output voltage stable during daily use.

Upgrade from a depleted or lower-capacity unit

Install this pack when the original cell no longer holds a useful charge or when a lower-watt-hour battery shipped with the system. The 63Wh capacity matches the factory specification for the listed Latitude models, so the performance jump is worthwhile whenever the existing battery falls short of a full workday.
