DI4 GYRO LASER 2500 Replacement Battery 14.4V 2600mAh

DI4 GYRO LASER 2500 — 14.4V Li-ion Replacement Battery

This is a 14.4V, 2600mAh Li-ion replacement battery for the DI4 GYRO LASER 2500 cordless stick vacuum. It slots into the same position as the original pack and connects through the existing charge port and motor circuit. When the factory battery starts cutting cycles short, this pack restores full voltage to the suction motor.

• GYRO LASER 2500 compatibility: The 2500 platform runs a 14.4V motor rail with a BMS that monitors cell voltage and draw rate. This pack matches that voltage rail and carries a protection circuit calibrated to the current thresholds the vacuum's controller expects.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the GYRO LASER 2500 motor circuit. The BMS handled full-load suction draws without tripping, and the charger handshake completed normally on every cycle.
• Dock charging behaviour on this vacuum: Do not leave the GYRO LASER 2500 sitting on the dock continuously. Cordless vacuums on permanent trickle charge develop capacity fade faster than those removed after a full charge. Charge fully, then pull it off the dock.

Suction dropping before the battery indicator reaches low

On the GYRO LASER 2500, suction loss often happens while the battery indicator still shows charge remaining. The motor draws harder when the filter is partially blocked, pulling more current than the BMS's sustained-draw threshold allows. The BMS responds by stepping the cell output down before the indicator catches up. Clean the filter first — if suction recovers, the battery was fine and the restriction was the cause.

Motor cuts out mid-clean then comes back on its own

This is a BMS overcurrent trip, not a dead battery. When restricted airflow — from a clogged filter or blocked nozzle — forces the motor to work harder, the current spike crosses the BMS's trip point and it shuts output off to protect the cells. The pack resets once the draw clears, which is why the vacuum powers back on after a few seconds. Clear the blockage and check the filter before assuming the battery is at fault. If the trip persists on an unblocked machine, measure resting cell voltage — it should sit at or above 14.0V after a full charge.
