Dell 68Wh 7.6V 4-Cell Battery

This 68Wh lithium-ion battery replaces the original power source in compatible Dell laptops. It is built for users who need a direct-fit replacement to restore full mobile runtime. The four-cell pack delivers 7.6V output matching the factory specification.

Upgrade from a depleted or failing original pack

Swapping in this battery is worth it when the original no longer holds a useful charge or reports a permanent failure. It restores the designed capacity without requiring a higher-wattage charger or BIOS changes. Buyers who need a higher-capacity alternative or a different voltage should look elsewhere.

Straightforward user installation

The pack fits the designated battery bay and connects to the existing connector with no soldering or tools beyond a screwdriver. Alignment tabs prevent incorrect insertion. The most common issue is ordering the wrong variant among the four similar Dell batteries, so verifying the part number against the old unit is essential.

Questions about this item

Will this 4-cell 68Wh battery fit the same chassis as my original Dell GJKNX pack?

The listing states there are four different batteries for the same Dell model and they are not interchangeable; compare your original battery to the product photos to confirm the 4-cell 68Wh pack matches before ordering.

What is the correct order to connect the 7.6V 4-cell battery when installing it in my Dell laptop?

Insert the 68Wh pack into the battery bay until the latch clicks, then attach the connector to the motherboard header; the step often missed is securing the latch before plugging in the cable.

How long will the 68Wh lithium-ion cells hold a useful charge before they need replacing?

The battery carries a one-year replacement warranty covering defects in materials or workmanship; actual service life depends on charge cycles, temperature and usage patterns.
