No bundled accessories change the installation

The product ships as a standalone battery without cables screws or software. No additional hardware is included so the swap uses only the existing laptop latch and connector. Buyers who need a screwdriver kit or an external charger must source those separately.

Voltage and capacity match the original spec

The 14.8 V 2600 mAh rating mirrors the factory cell configuration ensuring the power management system recognises the pack without calibration issues. A different voltage or cell count would prevent the laptop from charging or reporting capacity correctly.

Questions about this item

When will the 4-cell 38 Wh lithium-ion pack need replacing?

The battery is a new 4-cell lithium-ion unit rated at 38 Wh and 2600 mAh; replacement timing depends on individual charge cycles and usage patterns.

What limits runtime during a full day of work on the 14.8 V 2600 mAh pack?

Capacity is fixed at 38 Wh, so runtime ends when the stored 2600 mAh at 14.8 V is depleted under your workload.

How much heat or noise does the OA04 replacement produce while charging all day?

The pack has no moving parts and generates only normal charging warmth; it runs silently.
