Questions about this item

Does the 18 V lithium pack use a slide-on or stem interface for the BSL 1815X and BSL 1830 tools?

The replacement battery matches the original BSL 1815X and BSL 1830 form factor, so it slides onto the tool’s rail exactly like the factory pack.

Will the 96.2 x 80.5 x 60.5 mm housing clear the battery bay on a Hitachi WH 18DSAL or DV18DBL?

Dimensions are 96.2 x 80.5 x 60.5 mm and weight is 420.0 g, matching the OEM spec for the listed Hitachi and Metabo HPT models.

Is there any calibration step after snapping the 1500 mAh pack into a FCG 18DAL driver?

No calibration is required; the pack has built‑in overcharge, over‑discharge, over‑voltage and short‑circuit protection and works immediately after installation.
