Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Ariete 271100ALUK Series — 14.4V Ni-MH Replacement Battery (AT5186005100)
This is a 14.4V, 2000mAh Ni-MH replacement battery for Ariete cordless stick vacuums, including the 271100ALUK, 271100AR0, 271100ARD, and 271100KEBG among others. It slots into the battery bay on the handle section and powers both the suction motor and the motorized brush head. Voltage and pack geometry match the OEM spec exactly.
- 271100-series platform fit: These models share the same 14.4V rail, connector pinout, and BMS handshake protocol across the range. One pack covers the full compatibility list without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a 271100-series unit. The BMS accepted the pack cleanly, thermal cutoff triggered at the correct threshold under a blocked-filter stress test, and the pack recovered to normal operation once the fault cleared.
- Dock charging habit on Ariete stick vacuums: Do not leave this vacuum sitting on the charging dock permanently. Ariete's dock delivers a trickle charge once full — continuous trickle on Ni-MH cells accelerates capacity fade. Charge to full and remove the unit from the dock.
Suction dropping before the battery indicator reaches low
This happens when the motor is drawing more current than the pack can sustain at full voltage — but the indicator hasn't triggered yet. A partially blocked filter is the most common cause. Restricted airflow forces the motor to work harder, pulling higher amps and causing the pack voltage to sag under load. Clean or replace the filter first, then test suction again at a measured 14.4V charge state before assuming the battery is at fault.
Motor cuts out mid-clean then recovers after a few seconds
This is a BMS overcurrent trip, not a dead battery. When suction is restricted — blocked brush head, clogged filter, or a rug fibre caught in the impeller — current draw spikes above the BMS threshold and the pack disconnects to protect the cells. After a few seconds the BMS resets and the vacuum runs again. Clear the blockage, check the brush roll for wrapped debris, and confirm the filter is clean before running the vacuum again.

Frequently Asked Questions
My Ariete cordless vacuum loses suction halfway through a clean but the battery light doesn't show low — what's happening?
This is voltage sag under load, not a dead battery. A restricted filter forces the motor to draw more current than normal, pulling the pack voltage down before the indicator reacts. Clean the foam and mesh filters thoroughly and check the brush head for wrapped fibres. After clearing the restriction, charge the pack fully to 14.4V and test again — suction should hold consistently through a full clean.
The vacuum ran for much shorter than expected straight out of the box — is the replacement battery faulty?
A partially blocked filter is the most likely cause. When airflow is restricted, the motor works harder and draws significantly more current than rated, depleting the 2000mAh pack faster than normal. Check that both the fine filter and foam filter are clean and fully dry before use — a damp filter restricts airflow nearly as badly as a clogged one. Swap to a known-clean filter, do a full charge cycle, and run again before assuming a cell fault.
The replacement battery won't charge on the Ariete dock — the indicator just blinks and stops.
Some Ariete chargers expect a BMS handshake voltage above a minimum threshold before beginning a charge cycle. If the replacement pack has been stored discharged for a period, the resting cell voltage may be too low for the charger to recognise it. Remove the pack, leave it at room temperature for 30 minutes, then reseat it firmly in the dock — connector contact issues cause the same symptom. If the charger still rejects it, try a compatible Ni-MH charger that supports a 0V recovery mode to bring the pack up to 10.8V before returning it to the dock.
