GreenTech 72WHR replacement for Precision

This 6-cell lithium-ion battery delivers 11.1V and 6486mAh capacity for Dell Precision 7510, 7520, 7710 and 7720 models. It replaces OEM part numbers including 451-BBSE, T05W1 and GR5D3. Mobile professionals who need a direct swap for the original pack will find the correct voltage and form factor here. Buyers with ultrabooks or consumer laptops requiring a different connector or voltage should look elsewhere.

Sustained output with circuit protection

The pack is tested for stable current delivery and low self-discharge during extended work sessions. Built-in circuit protection guards against over-charge, over-discharge and short-circuit conditions. Users running compute-intensive tasks on Precision 15 or 17 chassis can expect consistent voltage without sudden drops. The battery is not designed for hot-swap operation or external charging docks.

Certified safety and thermal stability

CE, FCC and RoHS certifications confirm compliance with electrical safety and substance restrictions. The lithium-ion chemistry maintains temperature within normal operating limits for the supported Precision chassis. No additional cooling or fan control is required beyond the laptop's own thermal management. Buyers needing a higher-capacity 9-cell pack or a different voltage platform will not be served by this model.

Questions about this item

How much heat does the 11.1V 72WHR battery generate during all-day use?

The 6-cell lithium-ion pack runs at 11.1V and 72WHR; it produces only normal warmth under load and includes circuit protection for stable current.

Which Dell Precision models must I already own for this T05W1 battery to fit?

It fits Precision 15 7510, 7520, M7510 and Precision 17 7710, 7720, M7710 — check your service tag against OEM numbers 451-BBSE, T05W1, 0FNY7, GR5D3, 1V0PP or MFKVP.

Will the 6486mAh capacity work correctly with the original charging circuit in a 7510 or 7710?

Yes — the GreenTech cell matches the OEM 11.1V 72WHR spec, so the laptop's existing charger and firmware recognise it without modification.
