The BL1860B is the right battery for users who run Makita 18V tools heavily throughout the day. The 6.0Ah capacity extends run time meaningfully compared to the 5.0Ah BL1850B, and Star Protection adds a real layer of durability. The price premium is justified for professional or near-daily use — less so for occasional home tasks.
Pros
6.0Ah capacity — longest run time in the standard LXT line
Star Protection monitors load and temperature in real time
3-stage LED charge indicator on the battery itself
Compatible with all 18V LXT tools (100+ models)
Charges in ~55 min with DC18RD rapid charger
Cons
Heavier than BL1850B — noticeable with drills overhead
Higher price than the 5.0Ah version
Star Protection only activates with compatible tools
No USB charging output

BL1860B vs BL1850B — Which Should You Buy?
The most common decision Makita users face: 6.0Ah or 5.0Ah. The difference is more practical than it might appear on spec sheets.

Verdict: If you run tools for 4+ hours a day, the BL1860B is worth the price difference — fewer interruptions for charging. If you pick up the drill a few times a week for home projects, the BL1850B saves money and weight without a meaningful trade-off. Full side-by-side: BL1860B vs BL1850B comparison.

Tool Compatibility
The BL1860B fits every Makita 18V LXT tool made since 2005. That includes the full range of corded-replacement tools Makita has released over the past two decades — well over 100 products on the same platform.
Drill/Driver (DDF series)
Impact Driver (DTD series)
Circular Saw (DSS series)
Reciprocating Saw (DJR series)
Jigsaw (DJV series)
Angle Grinder (DGA series)
Random Orbit Sander (DBO series)
Rotary Hammer (DHR series)
Blower (DUB series)
String Trimmer (DUR series)
Vacuum (DCL series)
Multi-Tool (DTM series)
Important: The BL1860B is compatible with 18V LXT tools only. Makita also makes 12V CXT, 40V XGT, and 36V tools — these use different batteries and the BL1860B will not fit them. Always confirm your tool is labeled 18V LXT before purchasing.
Star Protection — What It Actually Does
Star Protection is Makita's communication system between the battery and the tool. When both the tool and the battery support it, the system monitors three conditions in real time: overload (pulling more current than rated), over-discharge (draining below safe cell voltage), and overheating.
When it detects a condition approaching a threshold, it reduces power before damage occurs — rather than simply shutting off after damage has already started. Over years of use, this translates into longer cell life and more consistent performance.
The practical limitation: Star Protection only activates when the tool also supports the protocol. Older 18V LXT tools (pre-2012 roughly) will still accept and use the BL1860B — they simply won't trigger the protection circuits. The battery functions normally; it just loses the communication layer.

Frequently Asked Questions
What tools is the Makita BL1860B compatible with?
The BL1860B is compatible with all Makita 18V LXT tools — drills, impact drivers, circular saws, reciprocating saws, jigsaws, angle grinders, and more. It uses the same slide-mount connection as every 18V LXT battery made since 2005. If your tool is labeled 18V LXT, the BL1860B will fit and work.
What is the difference between the BL1860B and the BL1850B?
The BL1860B has 6.0Ah capacity versus 5.0Ah on the BL1850B. In practice, this means roughly 20% more run time per charge. The BL1860B is also slightly heavier. Both share the same Star Protection system and LED indicator. If you run tools for extended periods without stopping, the BL1860B is worth the price difference. For occasional use, the BL1850B is sufficient.
How long does the Makita BL1860B take to charge?
With the Makita DC18RD rapid charger, the BL1860B charges in approximately 55 minutes from fully depleted. Standard chargers (DC18SD) take around 75 minutes. The battery's LED indicator shows three stages: two lights indicate partial charge, three lights indicate full charge.
Is the BL1860B compatible with older Makita 18V tools?
Yes — the BL1860B is backward compatible with Makita 18V LXT tools going back to 2005. The only exception is tools in the older Makita 18V NiMH or B-series platform, which use a different battery mount. Check that your tool is specifically labeled 18V LXT before purchasing.
What does Star Protection do on the BL1860B?
Star Protection is Makita's communication protocol between the battery and the tool. It monitors and protects against overloading, over-discharging, and overheating in real time. When the battery detects a condition that could damage the cells, it reduces or cuts power before damage occurs. It requires a compatible tool to function — older LXT tools won't trigger the protection circuits but will still operate normally with the battery.
