Physical dimensions are 136.56 x 56.14 x 46.0mm and weight is 560.5g, ensuring correct fit in the battery compartment. Buyers who need a different voltage or lithium chemistry cannot use this pack.

Sustained output with integrated protection circuits

Under continuous cleaning cycles the protection circuits guard against over-discharge and overheating, maintaining stable output until the pack reaches its low-voltage threshold.

Questions about this item

How long will the 14.4V 2800mAh pack run my M-488 vacuum between charges?

The 40.32 Wh rating gives a theoretical energy figure; actual run-time depends on the vacuum's motor draw and floor setting, so treat it as a direct replacement for the original pack.

What connector or interface does this Ni-MH pack use to attach to the M-488?

It is built to the original battery's exact specifications, so the existing connector on the M-488 mates directly without adapters.

Will the 136.56 x 56.14 x 46.0 mm case fit inside the M-488 battery compartment?

Yes, the dimensions match the factory pack, and at 560.5 g it sits in the same mounting points.
