Our take on the Makita BL1840BDC1 18V LXT Lithium-Ion Battery and Charger Starter Pack (4.0Ah)

This is a starter pack pairing Makita's 18V LXT 4.0Ah lithium-ion battery with a rapid charger. The battery reaches a full charge in 40 minutes or less and has an on-board LED charge-level indicator. Makita rates it for up to 35% more run time per charge than the older 3.0Ah BL1830, and STAR Protection guards against overloading, over-discharging and overheating. It suits anyone already on the LXT platform who wants a spare pack and a second charger, and it is a sensible entry point for a first LXT tool bought bare.

  • No carry case or bag in the pack

Questions and answers

Is the 4.0Ah pack worth it over the 3.0Ah?
Makita rates it for up to 35% more run time per charge than the BL1830, so it lasts longer between charges. It is the better pick if you run tools steadily rather than in short bursts.
How long does the charger take?
Makita says the 4.0Ah battery reaches a full charge in 40 minutes or less on the included rapid charger.
Does it fit all Makita 18V tools?
It is an 18V LXT battery, so it fits tools on the LXT platform. It does not fit Makita's 12V CXT or 40V XGT tools.
What is in the box?
One 18V LXT 4.0Ah lithium-ion battery and one rapid charger. No tool, case or bag is included.
Can I leave the battery on the charger?
The charger is designed to charge the pack and STAR Protection guards against overcharging, but Makita's guidance is to remove the battery once charging is complete.
Is 4.0Ah enough for a circular saw?
It will run a saw, but a 4.0Ah pack drains faster in high-draw tools than a 5.0Ah or 6.0Ah pack. For frequent sawing, a larger LXT battery is the better match.
