Key Features
Overview
The Metabo HPT BSL1850MT 18V 5.0Ah T-PWR Tabless Battery (part 383582M) is a compact lithium-ion battery for Metabo HPT 18V cordless tools. This is an 18V power tool battery designed for extended runtime and high power output in a lightweight 1.3 lb pack.
T-PWR tabless cell technology reduces internal resistance, which Metabo HPT says lets the battery deliver power more efficiently and run cooler under heavy loads. That makes it a strong match for brushless 18V tools that pull hard, while staying light enough for overhead drilling and all-day driving.
Charging is quick: approximately 25 minutes on the UC36YSL2, 38 minutes on the UC18YSL3Q1Y, 75 minutes on the UC18YFSL, 93 minutes on the UC18DAQ4, and 150 minutes on the UC18YKSLQ1Y. A 4-stage fuel gauge shows remaining charge, and a rubber base keeps the pack from sliding and protects work surfaces.
This is an 18V-only battery. It does not power Metabo HPT 36V MultiVolt tools; for those, step up to the BSL3650MVT MultiVolt pack.
It is a good everyday battery for Metabo HPT 18V drills, impact drivers, saws, and lights, and a lighter-weight option where the 10.0Ah MultiVolt pack is more battery than you need.

At 1.3 lb, the BSL1850MT keeps 18V tools balanced while still delivering 5.0Ah of runtime.
- 5.0Ah T-PWR tabless cells
