Makita BL1830B 18V LXT Lithium-Ion 3.0Ah

Makita BL1830B 18V LXT Lithium‑Ion 3.0Ah Battery

The BL1830B prioritizes speed, mobility, and safety. It keeps tools lighter for overhead and all‑day work while recharging quickly to minimize downtime—ideal as a primary pack for compact tools or as a fast-turn backup for high-demand days.

At a Glance

• Capacity: 3.0Ah (approx. 54 Wh)
• Typical charge time: ~30 minutes with Rapid Optimum Chargers (e.g., DC18RC, DC18RD)
• Protection: Star Protection Computer Controls to reduce overload, overheating, and over‑discharge
• Fuel gauge: Onboard 4‑LED charge level indicator
• Compatibility: Works with 275+ Makita 18V LXT tools and LXT chargers; not compatible with 12V CXT or 40V max XGT

When to Choose This Battery

• Use if you want the lightest feel on impact drivers, drills, oscillating tools, trim/compact saws, nailers, or multi-tools.
• Use for short, high‑intensity tasks with frequent battery swaps and minimal downtime.
• Use as a balanced second pack to rotate while a higher‑capacity pack charges.

Consider a Larger Pack If

• You run high‑draw tools for long stretches (7‑1/4 in circular saws, grinders, blowers).
• You need fewer swaps on all‑day jobs—look at BL1840B (4.0Ah), BL1850B (5.0Ah), or BL1860B (6.0Ah).
• Your tool is 18V X2 (36V) and requires two batteries; larger Ah packs extend runtime.

Runtime Ballparks (Real‑World Use)

Actual results vary by tool, material, temperature, and technique, but this 54 Wh pack generally supports:

• Driving screws with a compact impact driver: roughly 150–300 #8 x 2–1/2 in screws in SPF.
• Drilling in wood with a mid‑range drill: ~30–60 holes with a 1/2 in spade bit.
• Cross‑cutting 2x4s with a 6‑1/2 in circular saw: ~20–35 cuts.
• Continuous sanding or grinding with compact tools: about 10–20 minutes of continuous load.

Charging and Care

• For fastest, safest results, use Makita Rapid Optimum Chargers (DC18RC single‑port or DC18RD dual‑port).
• Let the pack cool to room temperature after heavy use before charging.
• Avoid charging or storing below 32°F (0°C) or above 104°F (40°C).
• Long‑term storage: keep in a cool, dry place at ~40–60% charge and check every 3–6 months.
• Rotate packs to balance wear; clean contacts periodically with a dry cloth.

Compatibility Notes

• Fits all Makita 18V LXT slide‑style tools and LXT chargers.
• Not compatible with Makita 12V CXT or 40V max XGT systems.
• For 18V X2 (36V) tools, you must use two LXT batteries. Mixing different Ah ratings is acceptable, but runtime follows the smaller pack; use similar age/charge for best results.

Pros and Cons

• Pros: Light weight, quick 30‑minute recharge, onboard fuel gauge, broad LXT compatibility, strong protection electronics.
• Cons: Shorter runtime than 4.0–6.0Ah packs on high‑draw tools; more frequent swaps for all‑day cutting or grinding.
