Hoover ATN264R Compatible Battery 26.4V 3000mAh

Hoover ATN264R Series — 26.4V Ni-MH Replacement Battery (48006265)

This is a 26.4V, 3000mAh Ni-MH replacement battery for the Hoover ATN264R cordless vacuum range. It fits the ATN264R, ATN264R011, ATN264R1011, and ATV264BM011 models. Swap it in when your original cell can no longer hold enough charge to finish a cleaning run.

• ATN264R series compatibility: All four model variants in this range run the same 26.4V power rail and use the same connector and BMS handshake, so a single cell covers the entire lineup without modification.
• Bench tested on actual hardware: We cycled this battery through full charge and discharge passes on the ATN264R platform, confirming the BMS communicates correctly with the charger and that the motor controller receives a stable voltage through the full discharge curve.
• Dock charging discipline for Ni-MH cells: Do not leave the vacuum sitting on the charging dock between uses. Ni-MH chemistry is more susceptible to trickle-charge damage than Li-ion — continuous dock contact accelerates capacity fade. Charge to full, then remove the vacuum from the dock and store it off charge.

Suction dropping before the battery indicator reaches low

This happens when motor draw spikes under load — thick carpet, a partial blockage, or a clogged filter forces the motor to pull more current than the battery's internal resistance can sustain cleanly. Voltage sags under that load, and the motor controller reduces power before the BMS actually triggers a low-cell warning. The indicator reads mid-range, but effective voltage at the motor is already too low to maintain full suction. Clear the filter and check the brush roll for obstructions before assuming the battery is the cause.

Motor cutting out and recovering mid-clean

A momentary cutout followed by recovery points to the BMS tripping on an overcurrent event rather than a flat battery. On the ATN264R, this usually happens when sustained suction restriction — a blocked filter or a jammed brush roll — forces the motor to pull beyond the BMS's current threshold. The BMS cuts the circuit, the motor stops, and once current demand drops the BMS resets and power returns. Clean or replace the filter first; if cutouts persist on an unobstructed machine, check that resting voltage after a full charge reaches at least 26.4V before reinstalling.
