The Makita BL1850X4 quad pack is designed for professional contractors and serious DIYers who rely on high-drain 18V cordless tools for extended daily use. The primary benefit of this set is the substantial 5.0Ah capacity, which provides 66% more runtime than standard 3.0Ah models without increasing the battery's footprint, making it ideal for maintaining tool balance. While these batteries offer exceptional efficiency, they are specifically limited to Makita 18V LXT tools featuring the star symbol or yellow connector plate, meaning owners of older, legacy Makita tools may not be able to utilize this set.

These batteries are only compatible with Makita 18V LXT tools that have a star symbol on the connector plate or a yellow connector plate.
When using a Makita Rapid Optimum Charger (DC18RC or DC18RA), these 5.0Ah batteries charge in approximately 45 minutes.
The star symbol indicates that the tool is equipped with battery protection technology that communicates with the battery to prevent over-discharging and overheating.
Yes, they are compatible with most Makita LXT chargers, though charging times may be longer with non-rapid models.
Press the button on the battery side; the LED indicator will light up to show the remaining capacity.
Ensure the battery is fully clicked into the charger and check for debris in the connector terminals. If the charger light flashes red/green, the battery may be too hot or damaged.
The battery may have reached its cycle limit or experienced an internal cell fault. Check for signs of physical swelling or casing damage.
Verify that your tool is part of the 18V LXT lineup and features the required star symbol or yellow connector plate; this battery will not fit legacy non-star tools.
To ensure peak performance and battery longevity, these units must only be used with tools displaying the star symbol on the connector plate or those equipped with a yellow terminal connector. When setting up your workstation, place your DC18RC or DC18RA rapid chargers on a stable, flat surface with adequate ventilation to prevent overheating during the 45-minute charge cycle.
