Direct Replacement Battery

This 7.2V 1500mAh Ni-MH pack replaces the original GPHC152M07 cell in Dirt Devil EVO M678 and M678 handheld vacuums. It delivers 10.8Wh of energy and matches the factory voltage and capacity exactly. The 229.7g unit fits the original battery compartment without modification.

Ni-MH Chemistry Limits

Nickel-metal hydride chemistry self-discharges faster than lithium alternatives and benefits from a full charge before first use. The pack operates at a fixed 7.2V nominal voltage and cannot be fast-charged beyond the vacuum's built-in charger specification. Capacity will gradually decline over repeated cycles.

Simple Drop-In Installation

Installation requires opening the battery door, unplugging the old pack, and connecting the new one using the existing connector. The 49.2 x 42.2 x 28.2mm dimensions ensure alignment with the compartment ribs. The most common issue is reversed polarity if the connector is forced; verify the keyed plug orientation before applying pressure.

Questions about this item

What does the 1500mAh capacity mean for runtime in my Dirt Devil EVO M678?

The 1500mAh rating matches the original GPHC152M07 pack, so you should see the same cleaning time per charge that the vacuum delivered when it was new.

What does the 7.2V rating mean once the pack is installed in the machine?

7.2V is the nominal voltage the EVO M678 motor expects; the pack supplies that level throughout most of its discharge curve, keeping suction steady until the battery is nearly depleted.

What connector standard does this Ni-MH pack use and what does it limit?

It uses the factory keyed plug for the GPHC152M07 part number, which only fits the EVO M678 and M678 chassis, preventing accidental connection to other Dirt Devil models.
