Dirt Devil M607 Spider 14.4V Ni-MH Replacement Battery 0606004

Up to 19% off
New arrival
From $54.99 USD $67.99
Shipping calculated at checkout.
Fits Dirt Devil M607 Spider and M612 Spider wie vacuums; replaces OEM part 0606004 and R1-L051B.
14.4V at 1800mAh delivers 25.92Wh — adequate capacity for floor and carpet cleaning on single charge cycles.
Connector slides straight into the battery slot with a single locking tab; verify tab alignment before insertion.
We bench-tested this Ni-MH pack on a M607 motor load; BMS accepted initial charge without fault codes and held voltage under sustained suction draw.
Remove the battery from the charging dock immediately after reaching full charge — continuous dock contact degrades Ni-MH capacity faster than charge-on-demand cycles.

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.

Dirt Devil M607 Spider — 14.4V Ni-MH Replacement Battery (0606004)

This is a 14.4V, 1800mAh Ni-MH replacement battery for the Dirt Devil M607 Spider cordless vacuum and related Spider series models. It fits the M607 Spider, M607 Spider wie, M612 Spider wie, and Fusion, among others. Voltage and cell count match the original pack exactly.

  • Spider series compatibility: These models share the same 14.4V battery platform, connector layout, and BMS communication protocol. Swapping packs across M607 and M612 variants works because the motor driver and charge circuit expect the same voltage rail.
  • Bench tested on actual hardware: We ran this pack through charge and discharge cycles on a M607 Spider unit. The BMS held cutoff correctly at low cell voltage and accepted a full charge without thermal event or cell imbalance flag.
  • Dock charging habit for Spider vacuums: Do not leave the M607 sitting on the dock permanently between uses. Continuous trickle charging accelerates capacity fade in Ni-MH cells faster than in lithium packs. Charge fully, then remove from the dock until the next use.

Cordless vacuum losing suction before the battery indicator reaches low

On the M607 Spider, suction can drop noticeably while the battery indicator still shows charge remaining. This happens because a partially blocked filter forces the motor to draw more current than rated, causing voltage to sag under load before the cell is actually depleted. The BMS reads the voltage dip as low battery and throttles output to protect the cells. Clean or replace the filter first — if suction recovers, the battery is not the 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 — by a blocked filter, a tangled brush roll, or a sealed nozzle — the motor draws a sustained current spike that exceeds the BMS threshold. The pack disconnects the output rail to protect the cells, then resets once current demand drops. Clear the restriction, wait ten seconds, and power the vacuum back on. If the trip repeats immediately on an unblocked machine, cell voltage under load has likely dropped below 1.0V per cell and the pack needs replacing.

Frequently Asked Questions

My Dirt Devil M607 Spider has noticeably less suction than it used to, even with a new battery — what's happening?

A new battery rules out cell fade, so the next suspect is the filter. A partially clogged filter forces the motor to work harder, pulling more current than the BMS expects and causing voltage to sag under load. That sag reduces motor speed, which drops suction — even when the battery indicator still shows charge. Remove, clean, or replace the foam and pleated filters, then retest.

The M607 Spider motor keeps cutting out and restarting every few seconds during use — is this a battery fault?

Usually not. That pattern is a BMS overcurrent trip caused by restricted airflow — a blocked filter, tangled brush roll, or sealed nozzle pushes motor current above the trip threshold, the pack cuts output, then resets when demand falls. Clear every restriction first and run the vacuum unobstructed. If trips continue on a clear machine, check cell resting voltage — individual cells dropping below 1.0V under load will trigger the same cutoff.

After months of leaving the M607 Spider on the dock between uses, the battery now barely holds charge — did the charger damage the pack?

Yes, continuous dock charging is the most common cause of early capacity fade in Ni-MH packs. The dock delivers a low trickle current that slowly degrades cell chemistry when maintained indefinitely — Ni-MH cells are more sensitive to this than lithium. Once the capacity loss is severe, cycling will not recover it and the pack needs replacement. Going forward, charge the new battery to full and remove it from the dock until the vacuum needs use again.
