ETA 5225 90000 Cordless Vacuum Replacement Battery 14.4V 2600mAh

ETA 3225 Raggio Eco — 14.4V Li-ion Replacement Battery (5225 90000)

This is a 14.4V 2600mAh Li-ion replacement battery pack for the ETA 3225 Raggio Eco and 5225 Raggio cordless vacuums, as well as the 360 Robot Vacuum S6. It replaces OEM part 5225 90000 when the original pack no longer holds a useful charge. Dimensions are 132.40 × 36.80 × 21.00mm — verify before ordering if your unit has been modified.

• Raggio Eco, Raggio, and 360 Robot S6 compatibility: All three models share the same 14.4V battery architecture, connector pinout, and BMS communication protocol. One pack covers the full range without modification.
• Bench tested on actual hardware: We cycled this pack through discharge and charge sequences on the Raggio Eco platform. The BMS held stable cutoff thresholds under sustained motor load and responded correctly to the charger handshake — no error codes or premature trips.
• Dock charging on the Raggio Eco: Do not leave the vacuum sitting on the charging dock permanently. Continuous trickle charging accelerates cell degradation faster than normal use cycles. Charge to full, then remove the unit from the dock until the next clean.

Cordless vacuum losing suction before the battery indicator reaches low

This happens when the motor draws more current than the BMS expects at a given state of charge. A partially blocked filter increases airflow resistance, forcing the motor to work harder and pull amps above the rated threshold. The BMS reads this as an overcurrent event and reduces power to protect the cells — suction drops even though the battery indicator still shows charge remaining. Clean or replace the filter first, then retest; the symptom usually clears without touching the battery.

Motor cuts out mid-clean and recovers after a short pause

This is a BMS overcurrent trip, not a dead battery. When restricted suction — caused by a clogged filter, blocked nozzle, or tangled brush roll — forces sustained high current draw, the BMS opens the discharge circuit and waits for the load to clear. The pack cools slightly, the BMS resets, and power returns. Fix the restriction first. If the cutout continues on a clean filter with a new battery, check that the discharge voltage under load stays above 12.0V — a reading below that points to a worn cell that needs replacement.
