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

🔹 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.

AEG CX7230 Series — 14.4V Li-ion Replacement Battery (6.01.52.06-0)

This 14.4V 1500mAh Li-ion battery replaces the original pack in the AEG CX7230 and CX72HO2 cordless vacuum cleaners, along with the AG 3103 series handhelds. It matches the OEM voltage rail and connector, so the vacuum's motor control circuit runs as expected from the first charge cycle.

  • CX7230 and AG 3103 platform fit: These models share a 14.4V BMS handshake and the same physical pack dimensions (102.90 × 90.70 × 41.30mm). The battery connector seats fully and the discharge curve matches what the motor controller expects across the full draw range — from hard-floor glide to sustained carpet mode.
  • Bench tested on actual hardware: We cycled this cell under a simulated blocked-filter load — the condition that pushes current draw highest on this platform. The BMS held the discharge curve without tripping into protective cutoff at normal operating amperage.
  • Dock charging discipline on the CX7230: Do not leave this vacuum sitting on the charging dock between uses. The CX7230's charger does not drop to a true maintenance mode — it continues to push a low trickle into the cell. Remove the battery or unplug the dock once the charge indicator clears.

Cordless vacuum losing suction before the battery indicator reaches low

On the CX7230, suction drops while the indicator still shows a healthy charge level because the BMS is responding to voltage sag, not state of charge. When the filter is even partially blocked, the motor draws more current than rated, pulling the cell voltage down momentarily below the BMS threshold. The battery reads "charged" at rest but cannot sustain voltage under load. Clean or replace the filter first — if suction recovers immediately, the cell is fine. If suction still sags on a clean filter, the pack has lost enough capacity that voltage sag under normal motor draw is triggering the same response.

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

This is a BMS overcurrent trip, not a motor fault. The CX7230 motor spikes current sharply when suction path resistance increases — a clogged filter or blocked nozzle is the usual cause. The BMS reads that spike as an unsafe draw and shuts the cell down for a few seconds before resetting. Clear the blockage, check the filter is seated correctly, and run the vacuum again. If cutouts persist on an unblocked machine, check cell voltage under load — a healthy pack should hold above 13.0V during normal floor cleaning.

Frequently Asked Questions

My AEG CX7230 used to clean a whole room on one charge — now it barely gets through half. The battery indicator still shows bars. What's happening?

Capacity fade is the cause — the cell holds less total energy, so the vacuum runs out of usable charge well before the indicator reaches low. Indicators on this platform read resting voltage, not true state of charge, so they lag behind actual capacity loss. Fit a new battery and baseline your cleaning range from the first full cycle. If runtime still disappoints, check the filter — a restricted airflow path forces the motor to draw harder and burns through any pack faster than rated.

The replacement battery isn't charging on the AEG dock — the charger light stays on or flashes but never completes. What's the fix?

The CX7230 charger checks for a BMS handshake before it starts a full charge cycle — if the cell voltage has dropped too low during storage, the charger may not recognise the pack as valid. Remove the battery, wait 60 seconds, and reseat it firmly. If the charger still won't initiate, measure the battery terminals with a multimeter — a reading below 10V means the pack has deep-discharged and needs a recovery cycle or replacement. A confirmed 14.4V nominal cell at rest should prompt a normal charge response from the OEM dock.

My AEG CX7230 battery lost capacity noticeably faster than the original did. I charge it every night on the dock. Is that the problem?

Yes — continuous dock charging is the most common cause of accelerated capacity fade on this platform. The CX7230 charger does not switch to a true maintenance mode once the cell is full, so leaving it docked overnight repeatedly pushes a low trickle through the cell. Li-ion chemistry degrades faster when held at full charge under continuous current. Charge the battery only when the vacuum needs it, and remove it from the dock — or unplug the dock — once the indicator shows full.
