Makita 193889-4 9.6V NiMH 2.6Ah Battery

A dependable replacement pack for legacy Makita 9.6V tools. The 2.6Ah NiMH chemistry provides more runtime than most 9.6V NiCd packs with less memory effect, helping older drills and drivers stay productive.

Key Specs

Part number	193889-4
Voltage	9.6V
Capacity	2.6Ah
Energy	~25Wh (9.6V × 2.6Ah)
Chemistry	Nickel-Metal Hydride (NiMH)
Typical use	Drilling, fastening, light-duty cutting on legacy 9.6V tools

When to Choose This Battery

• You own Makita tools specifically designed for 9.6V NiCd/NiMH packs that list 193889-4 or compatible 9.6V batteries in the manual.
• You want longer runtime vs. older 9.6V NiCd batteries with reduced memory effect.
• Your work is light to medium duty: assembling cabinets, driving screws, drilling pilot holes, light trim or PVC cutting.

When to Consider Alternatives

• Heavy-duty or all-day tasks: modern 18V/20V-class Li‑ion tools deliver significantly higher power and runtime.
• Extreme cold or heat: NiMH performance drops in very low temperatures; Li‑ion platforms handle temperature swings better.
• If your charger only supports Li‑ion: you’ll need a NiMH/NiCd-compatible charger for this pack.

Compatibility Notes

• For Makita tools built for 9.6V stick/pod-style NiCd/NiMH batteries. Always verify the tool and manual for 9.6V NiMH compatibility and the 193889-4 part number.
• Use with Makita chargers rated for NiMH/NiCd 9.6V packs. Check the charger label for supported voltages/chemistries.
• Not for Makita Li‑ion-only tools or chargers.

Performance & Runtime

At ~25Wh, expected runtime depends on load and duty cycle:

• Light work (e.g., 25–35W average): roughly 40–60 minutes of trigger time.
• Moderate work (e.g., ~50W): roughly 25–35 minutes.
• Heavy load (e.g., ~90W): roughly 12–18 minutes.

Actual results vary with tool condition, bit sharpness, material, and temperature.

Charging & Care

• First use: fully charge before operation.
• Charging time: about 1–3 hours depending on charger output (e.g., ~1A ≈ 2.5–3 hours; ~2–3A ≈ 1–1.5 hours).
• Let the pack cool to room temperature before charging; avoid rapid recharging when hot from use.
• Storage: keep in a cool, dry place. NiMH self-discharges; top up every 1–2 months if not used.
• Rotate multiple packs to balance wear; avoid deep discharge storage.

Safety

• Do not short the terminals or expose to fire/water.
• Use only with compatible tools and chargers; monitor during charging and unplug when complete.
• Recycle at an approved battery collection site when the pack no longer holds a charge.

FAQ

Will this work in all Makita 9.6V tools?

It fits Makita tools designed for 9.6V NiCd/NiMH packs that reference 193889-4 or compatible 9.6V part numbers. Check your tool’s battery compartment and manual to confirm.

Can I use my old NiCd charger?

Many Makita chargers that support NiCd also support NiMH in the same voltage range. Verify on the charger label; it should list NiMH and 9.6V compatibility.

Does NiMH have a memory effect?

NiMH is far less prone than NiCd, but partial memory can still occur. Regular full charges and avoiding repeated very shallow cycles help maintain capacity.

How can I maximize runtime?

Use sharp bits/blades, pre-drill when appropriate, avoid overloading the tool, and keep batteries at moderate temperatures. Carry a second pack for quick swaps.

What if I need more power?

For demanding, all-day applications, consider upgrading to a modern Li‑ion Makita platform with higher voltage and capacity for longer runtime and faster charging.
