Direct replacement for Latitude 7310 and 7410

This lithium-ion battery matches the original 11.4V 39Wh specification for Dell Latitude 7310 and 7410 series laptops. It replaces part numbers 35J09, WY9MP, XMV7T, YJ9RP and Y7HR3. The pack is supplied new in black and carries a 12-month warranty. Buyers needing a higher-capacity pack or a different voltage should look elsewhere.

Simple swap with no soldering required

The battery fits into the standard internal bay using the original connector and screw points. No tools beyond a small Phillips driver are typically needed. The main risk is ordering the wrong part number; verify the 35J09 code on your old cell before purchasing. If the laptop uses a different revision the connector will not seat properly.

Steady output through a full workday

The 39Wh rating delivers consistent 11.4V power across extended sessions rather than only brief peaks. Capacity remains stable during prolonged document editing, video playback or light development workloads. The 3255mAh cell chemistry resists voltage sag under continuous drain. Users running heavy compute tasks for many hours without mains power will need a larger pack.
