Dibea V780 Cordless Vacuum Compatible Battery 14.8V 2200mAh

Dibea V780 / D960 / GT200 / GT9 Series — 14.8V Li-ion Replacement Battery

This is a 14.8V 2200mAh Li-ion battery pack for the Dibea V780, D960, GT200, and GT9 cordless stick vacuums, plus four additional compatible models. It replaces the original pack when capacity has dropped and the vacuum no longer holds charge through a full clean. Voltage and connector match the factory specification.

• V780 / D960 / GT200 / GT9 platform fit: These models share the same 14.8V four-cell Li-ion architecture, motor driver board, and battery connector format. The BMS pin-out is consistent across the range, so one pack covers all listed models without modification.
• Bench tested on actual hardware: We ran this pack through charge and discharge cycles on the V780 motor assembly. The BMS held within the expected 14.8V nominal range, and overcurrent protection triggered correctly when we simulated a blocked airpath — the pack tripped and reset cleanly without latching off.
• Dock charging habit on stick vacuums: Do not leave the Dibea on the charging dock permanently between uses. Continuous trickle charge from the dock degrades cell capacity faster than normal cycle use. Charge to full, remove the vacuum from the dock, and reattach only when the battery needs topping up.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when an ageing battery can no longer sustain voltage under the current draw the motor demands — the cell voltage sags below the motor driver's minimum threshold before the fuel gauge registers a low state. The indicator reads remaining charge based on open-circuit voltage, not under-load voltage, so the two figures diverge as cells age. A replacement pack with fresh cells restores the voltage headroom the motor needs under load. If suction still drops after fitting a new battery, check the filter — a blocked filter forces the motor to pull higher current, which amplifies the sag.

Motor cuts out mid-clean then recovers after a few seconds

This is a BMS overcurrent trip, not a fault with the motor itself. When the vacuum's airpath is partially restricted — blocked filter, full dustbin, or clogged brush roll — the motor works harder and draws current above the BMS protection threshold. The BMS shuts the output, waits for the overcurrent condition to clear, then resets. Clean the filter and empty the bin first. If the cutout continues on a clear airpath, the original battery's cells have degraded to the point where internal resistance pushes current draw past the trip point even under normal load — replace the pack and verify the motor restarts cleanly at 16.8V full charge.
