Sigma BC-41 Battery Charger for BP-41

Sigma BC-41 Battery Charger

The Sigma BC-41 is a dedicated battery charger built for the Sigma BP-41 lithium-ion battery used in DP1 Merrill and DP2 Merrill cameras. It suits photographers who need a reliable way to keep spare batteries ready for extended shooting sessions. The unit is compact and lightweight, making it practical for travel and location work. Integrated safety features protect against overcharging, overheating and short circuits during every charge cycle.

Compatibility Check

Verify that you own a Sigma BP-41 battery and either a DP1 Merrill or DP2 Merrill camera before ordering. The charger is designed exclusively for that battery model and will not fit other Sigma or third-party cells. Confirm your camera uses the BP-41 so the charger matches your existing kit. No other battery types or camera bodies are supported by this accessory.

Thermals, Noise and Power

The charger operates silently with no moving parts, so it adds no audible noise to a studio or hotel room. Safety circuitry manages temperature during the 140 minute charge cycle, preventing overheating of the battery and charger housing. Power draw is limited to the requirements of a single BP-41 cell, keeping consumption low during normal use. The compact enclosure stays cool enough to handle safely throughout the charging process.
