Pyle PUCRC660 Replacement Battery 14.4V 2600mAh

Pyle PUCRC660 / PUCRC675 — 14.4V Li-ion Replacement Battery

This is a 14.4V 2600mAh Li-ion battery for the Pyle PUCRC660 and PUCRC675 cordless handheld vacuums. It slots into the same bay as the original cell and connects to the same BMS circuit. Capacity is 2600mAh (37.44Wh), matching the factory specification.

• PUCRC660 and PUCRC675 compatibility: Both models run the same 14.4V motor rail and use an identical battery bay with the same connector pin-out. The BMS in each unit communicates on the same signal line, so one cell fits both without modification.
• Bench tested on actual hardware: We ran the battery through charge and discharge cycles on a 14.4V motor load. The BMS held voltage within spec under sustained draw and tripped correctly when current spiked past the overcurrent threshold — then recovered cleanly on reset.
• Dock charging habit for the PUCRC series: Do not leave the vacuum sitting on the charging dock between every use. These units trickle-charge continuously when docked, which accelerates capacity fade. Charge fully, then remove from the dock until the next use.

Suction dropping before the battery indicator shows low on the PUCRC660

The motor on the PUCRC660 draws more current when airflow is restricted — a partially blocked filter is the most common cause. Under that extra load, pack voltage sags early even if cell capacity is fine. The vacuum's suction weakens noticeably while the LED indicator still shows a charge. Clean or replace the filter first, then retest — if suction normalises, the battery was not the problem.

Motor cuts out mid-clean and then restarts after a short pause

This is a BMS overcurrent trip, not a dead battery. When the motor works against a blockage or heavily soiled filter, current draw spikes past the BMS protection threshold and the circuit opens. The BMS resets automatically after a few seconds of no load, which is why the vacuum restarts on its own. Clear any blockage, clean the filter, and confirm the resting pack voltage reads at or above 14.0V before writing off the battery.
