42 Wh replacement battery

This 42 Wh lithium-ion battery is designed for Dell Inspiron 14 and 15 models including the 5480, 5485, 5491, 5493, 5585, 5590, 5593, 5594 and 5598. It suits owners of those laptops who need a new power source because the original cell has degraded or failed. The four-cell pack operates at 11.4 V and carries CE and RoHS certification. Buyers who cannot match the physical shape shown in the product photos should not order this unit.

Lithium-ion chemistry limits

Lithium-ion cells lose capacity gradually with each charge cycle and are sensitive to deep discharge and high temperatures. The pack cannot be revived once its internal chemistry degrades beyond a usable threshold, so a replacement will eventually be required again. The battery is not designed for user servicing and must be recycled according to local regulations when exhausted. Users who need a battery that can be rebuilt or that tolerates extreme heat should look elsewhere.

42 Wh capacity headroom

A 42 Wh pack typically powers compatible Inspiron laptops through several hours of office work, web browsing or video playback on a single charge. Runtime shortens under heavy processor loads, high screen brightness or when multiple peripherals draw power. The one-year replacement warranty covers defects in materials and workmanship but does not extend the chemical lifespan of the cells. Users who regularly work away from mains power for a full day will need to carry a charger or a second battery.
