Questions about this item

How many years before the 36Wh lithium-ion pack needs replacing?

The battery is brand new with a 12‑month warranty; lithium‑ion cells typically last several years of daily charging before runtime drops noticeably.

What stops the 11.25V battery from running longer under heavy load?

The 36Wh capacity is the hard limit — once that energy is used the laptop must recharge, regardless of workload intensity.

Does the 36Wh pack get hot or noisy during all‑day use?

No moving parts and low internal resistance mean silent operation and only mild warmth under continuous load.
