About this product

The Makita BL1850B is an 18V 5.0Ah lithium-ion battery designed for use across the extensive Makita LXT cordless tool platform. This genuine Makstar battery pack delivers extended runtime for improved productivity on site, making it an essential power source for professional tradespeople and serious DIY users. Featuring Star Protection Computer Controls technology, this battery benefits from comprehensive safeguards including overload, over-discharge and overheating protection to ensure longevity and reliability. The low self-discharge design means the battery retains its charge during storage, whilst the integrated LED charge level indicator allows you to monitor remaining capacity at a glance. Charging time is kept to just 45 minutes when paired with a Makita rapid charger, minimising downtime between tasks. Despite its 5.0Ah capacity, the battery maintains the same compact size and weight as the 3.0Ah, 4.0Ah and 6.0Ah variants in the LXT range, ensuring excellent balance and handling across all compatible tools. This makes it ideal for demanding applications such as drilling, cutting and fastening tasks where sustained power is required without frequent battery changes.
