Replacement battery for Dell Inspiron 13/14/15/17

This new FOCUSTEC lithium-ion battery replaces the original pack in Dell Inspiron 13, 14, 15 and 17 series notebooks. It is built with Grade A cells and includes built-in circuit protection for stable output and safety. The pack suits owners who need a direct swap for a worn or failed unit. It is not for buyers who need a higher-capacity design or a different voltage platform.

Voltage and capacity match: 11.4 V, 42 Wh, 3-cell

The single specification that decides fit is the electrical rating: 11.4 volts and 42 watt-hours in a three-cell lithium-ion layout. This matches the Dell part numbers 3CRH3, T2JX4, FC92N, CYMGM and the long list of compatible P/Ns. If your original battery shows a different voltage or watt-hour value, this pack will not work correctly.

Thermal and power behaviour in daily use

Grade A cells and the integrated protection circuit limit heat build-up and prevent over-current during normal charging and discharging. The supplier recommends an initial conditioning cycle: discharge to 5 percent, charge to 95 percent, and repeat three to four times. After conditioning the pack delivers steady voltage with minimal self-heating under typical office workloads.

Questions about this item

How long will the 42Wh capacity run my Dell Inspiron 15 5567 on a full charge?

The 42Wh rating means the battery stores 42 watt-hours of energy; actual runtime depends on the laptop's power draw, screen brightness and workload, so it varies by model and usage.

Does the 11.4V voltage match the original Dell 3CRH3 battery specification?

Yes, this replacement is rated at 11.4V, which matches the voltage of the Dell 3CRH3, T2JX4, FC92N and CYMGM part numbers listed for the compatible Inspiron 13, 14, 15 and 17 models.

Will this 3-cell pack fit the battery bay of a Dell Inspiron 17 5767 without modification?

The battery is built as a direct replacement for the listed part numbers including those used in the Inspiron 17 5765 and 5767, so it fits the existing bay and connector without modification.
