Battery DELL Latitude 7490 V4940
This Dell V4940 battery is designed specifically for Dell Latitude 7490 laptops, delivering reliable mobile power based on lithium-ion technology. The pack restores portable runtime for systems with depleted or worn-out batteries and supports typical daily use such as office work, web browsing and video playback. It is a direct-fit replacement that matches the original form factor and connector arrangement of Latitude 7490 models.
The lithium battery chemistry offers stable voltage and consistent discharge behavior for predictable runtime. At approximately 0.3 kg the pack is lightweight, which maintains the laptop’s portability and does not add significant bulk. Installation is straightforward and designed to fit the Latitude 7490 internal bay without modification, helping to quickly restore full battery functionality. Built to meet Dell’s physical dimensions and electrical requirements, the battery supports efficient energy management and typical power-saving features of the laptop.
Power down the laptop and disconnect the AC adapter before beginning. Remove the service cover or back panel according to the Latitude 7490 service instructions, then unplug the existing battery connector and remove the old pack. Fit the replacement battery in the same orientation, connect the battery cable securely to the motherboard, and reassemble the cover. Reconnect the AC adapter and allow the system to detect and charge the new battery; performing a full charge cycle after installation is recommended to calibrate the battery meter.
For best long-term performance, avoid deep discharges where possible, keep firmware and power-management drivers up to date, and store the battery at moderate charge (around 40–60%) if not used for extended periods. Use the original or Dell-certified AC adapter for charging and follow standard safety precautions for lithium batteries: avoid exposure to high heat, physical damage, or liquids.
