No bundled accessories or software

The package contains only the single battery unit; no cables, tools, drivers or management utilities are supplied. Installation relies on the existing latch and connector in the laptop, so the swap is a mechanical exchange without extra configuration steps. The omission means buyers who need a charging cable or external dock must source those separately.

Black lithium-ion housing

The black casing follows the factory form factor and aligns with the laptop’s internal rails and screw points, allowing the pack to seat securely without modification. The connector pin-out mirrors the OEM design, so the battery communicates with the embedded controller for charge reporting and thermal monitoring exactly as the original unit did. Users who require a higher capacity than 89Wh or a different voltage will need a different part number.

Questions about this item

How long will the 89Wh lithium-ion cell hold a useful charge before it needs replacing?

A lithium-ion pack of this capacity typically delivers several hundred full cycles; with daily charging you can expect years of service before capacity drops enough to warrant a swap.

What stops the 15.12V 89Wh pack from running longer during an all-day workload?

The 89 watt-hour rating is the hard ceiling — once the stored energy is used the system must recharge, so sustained heavy draw hits that limit first.

Does the battery get hot or make noise when the laptop runs flat-out all day?

The pack itself has no moving parts and runs silently; warmth depends on the laptop's cooling design and how hard the CPU and GPU are pushed.
