Hitachi 330067 18V 3.0Ah Lithium Ion Battery BSL1830

The Hitachi 330067 is an 18-volt lithium-ion battery with a 3.0 amp-hour capacity, designed for use with Hitachi's 18V slide-type cordless power tools. Lithium-ion chemistry delivers several advantages over older NiCad batteries: it maintains consistent voltage output throughout the discharge cycle, has no memory effect requiring full drain-and-charge cycles, and holds its charge longer during periods of non-use. The 3.0Ah rating positions this battery as a mid-range option—sufficient for most drilling, driving, and cutting tasks without the added weight of higher-capacity cells.

Since Hitachi Power Tools rebranded to Metabo HPT, this battery remains relevant for users who own tools from either era of the 18V platform. Its relatively compact and lightweight form factor makes it well-suited for overhead work or situations where tool weight matters. Buyers should note that a compatible lithium-ion charger is required and sold separately, and that those with heavy-duty or all-day runtime needs may want to supplement with a higher-capacity battery.
