The Makita BL1850B LXT Battery Duo Pack comprises two 18V 5.0Ah lithium-ion batteries with a battery level indicator, designed to be compatible with a wide range of Makita power tools. This dual battery pack ensures a continuous workflow by allowing one battery to be charged whilst the other powers your tools. The lithium-ion technology delivers consistent power output with minimal self-discharge when not in use. Each battery features a built-in indicator that displays the remaining charge level, allowing users to monitor the power status whilst working. Compatibility with the 18V platform makes these batteries suitable for a range of Makita cordless tools, including drills, impact drivers, circular saws and other 18V LXT system tools. With a capacity of 5.0Ah, these batteries offer extended runtime for demanding applications and reduce the frequency of recharging breaks during longer work sessions. The compact design maintains ergonomic balance when fitted in compatible tools, whilst the robust construction withstands typical site conditions, including vibrations and impacts. These batteries utilise advanced cell technology that provides a stable voltage output throughout the entire discharge cycle, ensuring consistent tool performance. The pack comprises two identical batteries, allowing for efficient alternation between use and charging cycles. Proper maintenance involves storing the batteries at room temperature between 5°C and 25°C when not in use and avoiding complete discharge to ensure optimum battery life. LXT system compatibility ensures that these batteries work with Makita’s extensive range of 18V cordless tools, providing reliable power for both professional and DIY applications.
