Makita Usa Inc BL1820B 18V 2.0ah Lithium-ion Battery

Product Description

The MAKITA USA INC BL1820B is a compact 18-volt, 2.0Ah lithium-ion battery designed for use with Makita Star Protection-compatible power tools. It delivers consistent power output across a wide temperature range, including extreme cold down to -4 degrees F (-20 degrees C), making it reliable on outdoor and unheated jobsites year-round. The integrated LED charge level indicator lets the technician check remaining capacity at a glance without needing a separate tester. Built-in Star Protection Computer Controls guard against overloading, over-discharging, and overheating during operation.

This battery is suited for trade professionals who rely on 18-volt cordless tools in HVAC, plumbing, electrical, and general mechanical work. Its compact form factor reduces bulk in tight spaces, and the fast charge cycle — reaching full capacity in 25 minutes or less — minimizes downtime on the job. The impact-resistant outer case and shock-absorbing inner liner protect the battery cells during the physical demands of daily trade use. The battery also resists self-discharge, so it stays ready even after extended periods in storage between seasonal jobs.
