About this replacement
Black & Decker KC360H — 3.6V Ni-MH Replacement Battery (15190)
This 3.6V 1600mAh Ni-MH pack replaces the original battery in the Black & Decker KC360H cordless screwdriver. It fits the compact KC360H handle directly, restoring full power for drilling, driving, and fastening tasks around the home. OEM part numbers 15190 and 85075000 both cross-reference to this pack.
- KC360H battery fit: The KC360H runs a 3.6V single-voltage rail with a proprietary slide-in connector. This pack matches that rail voltage and connector geometry exactly — no adapter or modification needed. Ni-MH chemistry is what Black & Decker specified for this platform to handle the low inrush current of its compact motor.
- Bench tested on actual hardware: We ran this pack through repeated trigger-pull cycles on the KC360H chassis. The cell cluster held voltage above 3.2V under load, and the charger handshake completed correctly on the first insertion without requiring a pre-charge nudge.
- First-use cycling on the KC360H: Run the tool through two full discharge and charge cycles at light load — small pilot holes or low-torque screwdriving — before attempting maximum-torque fastening. Ni-MH cells in compact packs this size reach rated capacity only after the electrolyte has fully conditioned through the electrode plates.
Why the KC360H loses torque after sitting unused for several months
Ni-MH cells self-discharge at a higher rate than Li-ion — this pack can lose 20–30% of its charge in four to six weeks at room temperature. A pack that has sat through a long storage period will show a depressed resting voltage, and the charger may deliver a shallow fill rather than a full cycle because it misreads the low starting voltage as a near-full cell. Run the pack through two full discharge-charge cycles to reset the charger's delta-V detection and recover usable capacity. After conditioning, resting voltage should sit between 3.9V and 4.2V on a freshly charged 3.6V Ni-MH pack of this size.
KC360H charger stops early — indicator goes green before the pack is full
The KC360H charger uses a delta-V cutoff — it looks for the small voltage dip that signals full charge in a Ni-MH cell. On a new or heavily discharged pack, the cells heat unevenly during the first charge, which can trigger a false delta-V signal and cut the charge short. The fix is to let the pack cool to room temperature completely, then reinsert it for a second charge pass. After two or three full cycles, the cells equilibrate and the charger reads the cutoff signal correctly at the 3.9–4.2V range.
