Replacement Battery for Latitude E5450 E5550

This lithium-ion pack is built as a direct replacement for Dell Latitude E5450 and E5550 notebooks. It matches the original 7.4V voltage and 6500mAh capacity so the laptop recognises it without BIOS errors. The unit ships new and carries CE, UL and FCC safety certifications with built-in circuit protection.

51Wh capacity and 7.4V rating

The single specification that decides fit is the 51Wh energy rating paired with a 7.4V nominal voltage. Dell part numbers 0WYJC2, 8V5GX, R9XM9, WYJC2, 1KY05, 451-BBLN, 080-854-0066, TXF9M and 7V69Y all map to this exact rating, so any Latitude requiring those codes will accept the pack.

Up to 500 recharge cycles with Class A cells

Class A lithium-ion cells deliver up to 500 full charge cycles while maintaining low self-discharge and fast charging behaviour. The 6500mAh capacity provides typical all-day runtime for office workloads, but heavy GPU or sustained CPU loads will drain the pack sooner and require mid-day recharging.

Questions about this item

How long will the 51 Wh capacity actually run my Latitude E5450?

A 51 Wh pack typically delivers several hours of mixed office work on a Latitude E5450 or E5550; exact runtime depends on screen brightness, workload and battery health.

What connector does the G5M10 use and does it limit charging speed?

The battery uses the standard Dell Latitude E5450/E5550 connector, so it charges at the laptop's normal rate without any speed cap from the pack itself.

Will this 6500 mAh unit fit inside my E5550 without forcing the case?

Yes, the G5M10 is built to the original Dell dimensions for the E5450 and E5550 series, so it slides into the battery bay and locks without modification.
