No. It works only with Star Protection tools, marked with the Star Symbol or a yellow battery receiver. Older LXT tools without that marking won't accept it.

How long does it take to charge?

Makita rates it at 45 minutes or less to full charge on a compatible Makita charger. The charger is not included.

How does it compare with the BL1830?

It has 5.0Ah against the BL1830's 3.0Ah, and Makita claims up to 65% more runtime per charge. It is also heavier.

Does it work in cold weather?

Makita rates it for use down to -4°F/-20°C, and owners report consistent power in winter.

Ten 18V LXT 5.0Ah batteries. No charger and no tool are included.

Is the ten-pack worth it for a home user?

Only if you run several LXT tools or share a kit with a crew. A single pack or a smaller multi-pack covers most home use.

About the Makita BL1850B-10 18V LXT Lithium-Ion 5.0Ah Battery, 10 Pack

This is a 10-pack of Makita BL1850B-10 18V LXT lithium-ion batteries. Each battery has a 5.0Ah capacity and provides up to 65% more run time per charge than the BL1830. A built-in LED indicator shows the charge level.

Each battery reaches full charge in 45 minutes or less. It delivers consistent power and run time in extreme temperatures, including winter conditions down to -4°F (-20°C). It resists self-discharge, so it stays ready for use after long periods of storage.

Star Protection Computer Controls guard against overloading, over-discharging and over-heating. The outer case is impact-resistant, and a shock-absorbing inner liner protects the cells. Sixteen contact terminals keep a constant connection with the tool, which helps prevent power loss or fluctuation during high-vibration use. The battery works only with Star Protection tools, which are marked with the Star Symbol and/or have a yellow battery receiver under the tool.
