Questions about this item

How long will the 62 WHr capacity keep my notebook running on a single charge?

The 62 WHr rating measures stored energy; actual runtime depends on the notebook's power draw, screen brightness, workload and battery health, so real-world duration varies by system and usage.

Does this 4-cell lithium-ion battery use a proprietary Dell connector or a standard interface?

The battery is designed as a direct replacement for supported Dell notebooks and connects via the manufacturer's proprietary interface for those models.

Will the 451-BBUN battery fit my Dell laptop without modification?

The 451-BBUN is a customer-installable 4-cell pack built to match the chassis and mounting points of compatible Dell notebooks, requiring no extra brackets or adapters.
