Replacement lithium-ion battery

This 14.4 V 2600 mAh lithium-ion pack replaces the original battery in compatible vacuum cleaners. It uses a 4S1P cell arrangement with a fully decoded chip so the device recognises it immediately. Dimensions are 69.80 x 36.90 x 36.70 mm and weight is 190.0 g. The pack carries ISO9001, RoHS and CE certification.

Compatibility and limits

Suits owners of the 800T, 820S, 820T, 830T, PR-800T, PR-820T, PR-830S or PR-830T vacuums whose original part number is INR18650-M25-4S1P. Buyers who need a different voltage, a higher capacity or a different physical size should look at other options. The battery is not designed for devices outside the listed model range.

Decisive specification

The 14.4 V nominal voltage combined with the 2600 mAh capacity and the exact 69.80 x 36.90 x 36.70 mm form factor determine whether this pack fits and powers the target vacuum. If your machine requires a different voltage or cannot accept these dimensions, this unit will not work.

Questions about this item

Will the 14.4 V 2600 mAh pack fit my PR-820T vacuum without modifications?

The replacement cell matches the original INR18650-M25-4S1P part number and the 69.80 x 36.90 x 36.70 mm footprint, so it slots into the PR-820T and the other listed models directly.

How can I verify the battery is delivering the rated 37.44 Wh after installation?

Run the vacuum through two or three full charge-discharge cycles; the runtime should then match the original specification and the built-in protection chip will report normal voltage levels.

Does the box include a charger or only the 190.0 g battery itself?

Only the lithium-ion battery pack is supplied; the original vacuum charger is reused for charging.
