Replacement Battery for Dell Inspiron 15 7559 7567

This 11.1V 74Wh Li-Polymer battery replaces Dell part numbers 357F9 00GFJ6 0357F9 P57F001 and fits Inspiron 15 7559 7567 7566 7557 7556 5576 5577 7759 and 7000 Series Gaming Editions. It is built for owners of those specific Dell laptops who need a new power source that matches the original capacity and voltage. Buyers with other Dell models or non-Dell laptops cannot use this battery.

74Wh Capacity and Li-Polymer Chemistry

The 74Wh 6330mAh rating restores the runtime Dell specified for the listed Inspiron models so gaming sessions and workdays last as long as they did with the original pack. Li-Polymer construction is lighter than standard Li-Ion and includes protection against overcharge overheating and short circuits. No software or drivers are bundled; the improvement comes solely from the fresh cells and the safety circuitry inside the pack.

Drop-In Installation With Calibration Step

The battery is shaped to fit the listed Inspiron chassis without modifications and connects to the existing motherboard header. After fitting the pack the supplier recommends a full charge discharge cycle so the firmware reports an accurate percentage. The most common issue is skipping that calibration which leaves the gauge stuck at 0 or 100 percent until the cycle is completed.

Questions about this item

How many charge cycles can the 74Wh Li-Polymer battery handle before it needs replacement?

The battery is rated for 500+ charge cycles with proper care, after which capacity will gradually decline and a replacement will be needed.

What is the first limit reached during sustained gaming on the Inspiron 7000 series with this 11.1V battery?

The 74Wh capacity is the primary limit; it determines how long the laptop runs before requiring a recharge under heavy load.

Does the 6330mAh battery get hot or noisy during all-day use?

The battery has no moving parts so it is silent; it may warm up during extended use but includes protection against overheating.
