Questions about this item

How long before the 36Wh 11.4V Li-polymer cell needs replacing?

The 3220mAh cell degrades with each charge cycle; expect reduced runtime after several hundred full cycles, then replace when it no longer holds a useful charge.

What limits runtime first during continuous use on this 36Wh pack?

The 36Wh capacity sets the runtime ceiling; sustained loads drain the 3220mAh cell until the 11.4V output drops below the laptop's minimum operating voltage.

Does the battery get hot or noisy during all-day operation?

Li-polymer cells run silently; warmth is normal under load but the pack has no moving parts and no fan, so noise is not a factor.
