Cameron Sino Battery for Electrolux PQ91-50MB 2000mAh 25.2V

Direct Replacement Battery

This lithium-ion pack replaces the original power source in Electrolux cordless stick vacuums including the PQ91 and PQ92 model families. It delivers 2000mAh capacity at 25.2 volts for compatible handheld and upright units. Buyers who need a higher capacity cell or a different voltage platform cannot use this pack.

Exact Fit And Protection

The battery measures 87.00 x 82.00 x 54.60mm and weighs 350.0g, matching the factory dimensions for a secure slide-in fit. A fully decoded chip communicates with the vacuum electronics exactly like the original unit. Integrated safeguards guard against overcharge, over-discharge, over-voltage and short-circuit conditions. Shoppers whose device uses a different connector layout or mounting rail will find this battery incompatible.

Stable Output And Safe Handling

Rated at 50.40Wh, the pack supplies consistent power for normal cleaning cycles without voltage sag. Lithium-ion chemistry maintains steady discharge until the protection circuit activates at the low-voltage threshold. The cell operates safely within the vacuum's designed thermal envelope and requires no active cooling. Users who routinely run the vacuum until thermal shutdown or who charge with non-approved adapters will see reduced cycle life.
