Dell 42Wh Lithium-Ion Replacement Battery

This 42Wh lithium-ion battery replaces the original Dell unit for compatible notebook models. It uses a three-cell design rated at 11.4V and fits part numbers including 3DDDG, 3VC9Y, 03VC9Y, O3VC9Y, 049XH, 45N3J, 80JT9 and 451-BBZP. The unit is supplied new with CE and RoHS certification.

Capacity and Runtime

The 42Wh capacity provides a full charge for everyday office tasks, web browsing and media playback on supported Dell laptops. Runtime scales with screen brightness, processor load and connected peripherals, so heavy workloads will deplete the pack faster than light use. The three-cell layout limits total energy storage compared to larger six-cell or nine-cell alternatives.

Direct Replacement for Listed Part Numbers

This battery is a direct swap for the Dell part numbers listed above when the original pack matches the physical layout shown in the product images. It is not compatible with other Dell batteries that share the same laptop model but use a different connector or cell arrangement. Buyers must verify the exact part number before ordering.
