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.

iRobot Looj 330 Gutter Cleaning Robot — 7.2V Li-ion Replacement Battery (14570)
This 7.2V, 4000mAh Li-ion battery replaces part number 14570 in the iRobot Looj 330 gutter-cleaning robot. The Looj 330 uses this cell to power its auger motor and drive system as it moves through gutters dislodging leaves and debris. Capacity is rated at 28.8Wh, matching the original cell specification.
- Looj 330 compatibility: The Looj 330 and Looj 330 Gutter Cleaning Robot share the same battery bay dimensions, connector, and BMS handshake requirements — both accept the 14570 cell without modification.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Looj 330 platform and confirmed the BMS communicates correctly with the robot's power management circuit, including low-voltage cutoff behaviour at the correct threshold.
- Post-gutter-season storage: After the last gutter clean of the season, remove the battery from the robot entirely. Leaving the cell installed over winter in an unheated space accelerates capacity loss — store it indoors at around 50% charge until the next season.
Why the Looj 330 auger slows or stalls mid-gutter run
The Looj 330's auger and drive motors pull current simultaneously when the robot hits a dense debris pack. If the battery's internal resistance has risen — common in an aged cell — voltage sags under that combined load and the BMS may trigger a protection cutoff before the indicator shows critical. The robot appears to stall without warning. A fresh cell with low internal resistance holds voltage stable through that peak draw and keeps both motors running through the debris section.
Robot powers on but shuts off seconds after auger engages
This is a BMS overcurrent trip, not a motor fault. When the auger engages against a blockage or compacted debris, inrush current spikes sharply. A degraded battery cannot sustain that spike and the BMS cuts power to protect the cell. The robot restores power after a few seconds once the BMS resets. Clear the auger of any debris packing, confirm the battery is fully charged, and check that the cell voltage reads at least 8.0V off the charger before reinstalling.

Frequently Asked Questions
The Looj 330 cuts out seconds after the auger starts spinning, then comes back on — what's causing that?
That's a BMS overcurrent trip. When the auger hits compacted debris, inrush current spikes beyond what a degraded cell can sustain, so the protection circuit cuts power and resets. It's not a motor fault — it's the battery failing to hold voltage under peak load. Install a fresh cell and confirm it reads at least 8.0V off the charger before running the robot in a debris-heavy gutter.
My Looj 330 moves and runs fine indoors, but slows noticeably once it hits a packed section of gutter — is that a battery issue?
Yes. The auger and drive motors pull current at the same time when the robot pushes through dense leaves. If the battery's internal resistance has risen with age, voltage sags under that combined draw even though the indicator doesn't show low. The robot reads sufficient charge but can't deliver the current the motors need. A replacement cell with lower internal resistance will hold voltage stable through that load.
I stored my Looj 330 over winter with the battery installed and now the robot won't charge — how do I recover it?
Storing a Li-ion cell at low state-of-charge in a cold space can push it below the BMS re-initialisation threshold, causing the charger to see a dead circuit. Connect the charger and leave it for at least 60 minutes without interruption — some BMS controllers need that window to detect and trickle-charge a deeply discharged cell back into the recoverable range. If the charge indicator still shows no activity after 90 minutes, the cell has dropped below recovery voltage and needs replacing. Next season, store the battery indoors at roughly 50% charge.
