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.

iRobot Braava Jet M6 — 10.8V Li-ion Replacement Battery (ALB-C)

This is a 10.8V, 2600mAh Li-ion replacement battery for the iRobot Braava Jet M6 robot mop. It fits models M611020, M612880, and M612680, among others. The battery powers the mop's drive motors and cleaning cycle from the same voltage rail as the original cell.

  • M6 series compatibility: The Braava Jet M6 and its regional model variants — M611020, M612880, M612680 — all share the same 10.8V battery architecture and ALB-C form factor. The BMS handshake and connector are identical across this series, so one cell covers all listed models.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the M6 platform. The BMS accepted the replacement without error codes, held voltage through a full cleaning cycle, and the dock charger recognised it normally on the first seating.
  • Dock charging behaviour on the M6: The Braava Jet M6 parks on its dock between uses, which means it can stay on continuous trickle charge for days. Li-ion cells degrade faster under prolonged float charge. Remove the mop from the dock once the charge is complete, rather than leaving it docked indefinitely.

Why the Braava Jet M6 stops mid-clean on a new battery

The M6's BMS monitors cell voltage in real time during motor operation. If the drive motors or pump draw more current than the BMS threshold — caused by a partially blocked water nozzle or a dirty tank filter — the BMS will cut power to protect the cell. This can happen even with a fresh battery at full charge. Clear the nozzle and rinse the water filter before attributing a mid-cycle shutoff to the battery itself.

This happens when the dock contacts or the battery terminals have residue from water vapour or cleaning solution — both common in a robot mop environment. The charger cannot complete the BMS handshake through a resistive contact and reports the battery as flat. Wipe the gold dock contacts and the corresponding battery terminals with a dry cloth, then reseat the mop firmly. If the error clears, the cell voltage should read above 10.0V within the first few minutes of charge.

Frequently Asked Questions

My Braava Jet M6 stops cleaning halfway through a room even though the battery indicator isn't low — what's happening?

The M6's BMS trips on overcurrent before the fuel gauge reaches the low threshold. This usually means the water nozzle is partially blocked or the pump is working harder than rated, pulling more current than the BMS allows. Clean the nozzle and check the water tank filter first. If the mop completes a full cycle after that, the battery wasn't the problem.

The Braava Jet M6 cuts out, pauses, then restarts on its own — is that a battery fault?

That stop-and-restart pattern is a BMS overcurrent trip followed by automatic recovery, not a dead cell. It happens when sustained motor load — usually from a pump restriction or drive wheel resistance — briefly exceeds the discharge limit. Check that the drive wheels spin freely and the spray nozzle isn't clogged. A cell fault would cause a full shutdown without recovery, not repeated cycling.

My replacement battery charges fine but the M6 runs noticeably less than it used to — why?

A partially blocked spray nozzle or a dirty tank filter forces the pump motor to draw above its rated current, which depletes a 2600mAh cell faster than normal — not because the battery is weak, but because the motor is working harder. Flush the nozzle with warm water and rinse the filter, then run a full cleaning cycle. If runtime improves, the issue was restriction load, not capacity loss.
