Fits Makita 4093D drill and replaces OEM part numbers 193889-4, 9033, 9034, 191681-2, 192533-0, 632007-4, 9000, 9001, 9002, 9600, 193890-9, 192696-2.
9.6V Ni-MH chemistry delivers 3000mAh capacity — sustains drill torque during fastener driving and hole drilling without voltage sag on motor startup.
Slide connector aligns flat against the tool's battery slot with a single locking tab at the base — seats fully until the tab clicks.
Bench testing confirmed the BMS accepts full charge cycles without early cutoff; the pack profiles motor inrush current on the first three trigger pulls without thermal shutdown under continuous drilling.
On first use, run the 4093D at half throttle for two cycles before driving heavy fasteners — allows the cell voltage regulation circuit to establish motor load baselines before maximum torque demand.

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.

Makita 4093D Series — 9.6V Ni-MH Replacement Battery (193889-4)

This is a 9.6V, 3000mAh Ni-MH battery for the Makita 4093D cordless drill/driver and a wide range of compatible Makita 9.6V tools including the 4190DB, 4190DWD, and 6095D. It matches the OEM voltage rail and physical connector of the original 193889-4 pack. Capacity is rated at 3000mAh (28.8Wh).

  • Makita 9.6V platform compatibility: These models share the same battery bay geometry, contact layout, and 9.6V nominal rail. The BMS in each tool communicates discharge state through the same two-contact interface, so one pack spans the full 9.6V lineup without modification.
  • Bench tested on actual hardware: We cycled this pack on a 4093D under repeated trigger pulls and sustained drilling loads. The BMS held discharge cutoff at 8.4V and returned stable voltage recovery between cycles with no unexpected thermal interruptions.
  • Motor inrush conditioning on first use: On first use, run the drill at half load for two cycles before applying full torque. This lets the BMS profile the motor's inrush current draw and calibrate overcurrent thresholds before you hit maximum load applications.

BMS cutoff on drill motor-start inrush surge

When you pull the trigger on a Makita 4093D, the motor draws a spike of current well above its running draw — often three to five times higher in the first milliseconds. On a new or cold pack, the BMS may read this spike as an overcurrent fault and cut the circuit before the motor even starts turning. Ni-MH cells are more tolerant of inrush than Li-ion, but a fully discharged or cold pack still raises internal resistance enough to amplify the voltage drop at that spike. If this happens, let the pack rest for two minutes at room temperature and retry at a lighter load setting first.

Tool bogs under load mid-drill and loses torque

If the drill starts strong but loses power and bogs halfway through a fastener or hole, the cause is usually voltage sag — the cell voltage drops under sustained current draw faster than the tool's regulator can compensate. On Ni-MH packs, this often signals either high contact resistance at the battery terminals or cells that have been repeatedly shallow-cycled and lost capacity. Clean the battery contacts on both the pack and the tool with isopropyl alcohol and check for oxidation or debris. If sag persists after cleaning, measure open-circuit voltage — a healthy fully charged 9.6V Ni-MH pack should read between 10.5V and 11.0V at rest.

Frequently Asked Questions

My Makita charger won't recognise this new pack — it just blinks and never starts charging. What's wrong?

A Ni-MH pack that has sat in storage can drop below the charger's acceptance threshold voltage, causing the charger to reject it as a fault condition rather than a depleted cell. Some Makita chargers require the pack to sit above roughly 1V per cell before the charge cycle initiates. To recover it, briefly connect a known-good 9.6V pack to warm the charger circuit, then swap in the new pack immediately — or use a universal charger set to Ni-MH at a low rate (0.1C) to bring cells up to acceptance voltage before returning to the Makita charger.

The drill cuts out the instant I pull the trigger hard — but works fine on slow speed. Is the battery at fault?

This is a BMS overcurrent trip caused by motor-start inrush current exceeding the pack's threshold at that moment. At high speed, the trigger opens the circuit fully and the inrush spike is at its worst — at slow speed the partial trigger limits current and the BMS doesn't trip. Let the pack rest at room temperature for five minutes, then start two or three drilling cycles at the lowest torque clutch setting before going to full trigger. This allows the BMS to establish an inrush baseline before it sees the full spike.

The drill runs fine indoors but feels noticeably weaker in the garage in winter. Is something wrong with the cells?

Nothing is wrong — Ni-MH internal resistance rises as temperature drops, which increases voltage sag under load and reduces usable power output. Below about 5°C, you can expect a meaningful drop in effective torque and fewer cycles before the pack needs charging. Bring the battery indoors and warm it to room temperature (around 20°C) for 30 minutes before use. Measure open-circuit voltage after warming — it should read between 10.5V and 11.0V on a fully charged pack before you put it back to work.
