Two-pack for Minolta MND20 and MN50WP

The Kastar NB-6L kit includes two lithium-ion batteries and a compact AC wall charger. Each cell delivers 3.7 volts and 1300 milliampere-hours, matching the original specifications for the Minolta MND20 44 MP camera and the MN50WP 48MP waterproof model. Photographers carrying either body gain a lightweight spare set that fits the existing battery compartment without modification.

Replaces ageing NB-6L cells

When the original packs no longer hold a full day of 2.7K or 5K UHD recording, this two-battery bundle restores practical shooting time. The charger accepts 100 to 240 volts AC, so it works worldwide without a separate adapter, and its foldable flat plug stores neatly in a gear bag. Swapping cells takes seconds, keeping both cameras ready for extended trips or back-to-back events.

Steady output during long sessions

Each battery stores 4.81 watt-hours and the charger supplies 4.2 volts at 600 milliamps, indicated by a red LED while charging and green when full. The lithium-ion chemistry maintains consistent voltage through continuous video capture, avoiding the sudden drops seen in worn packs. Heat stays low during repeated charge cycles, so the pair remains reliable for multi-day assignments.

Questions about this item

What battery slot size does the Kastar NB-6L pack need to fit inside the Minolta MND20 or MN50WP?

Each NB-6L cell is a 3.7 V 1300 mAh lithium-ion unit rated at 4.81 Wh, matching the original battery compartment of both cameras.

How do I use the foldable-plug charger correctly, and what step do users often miss?

Plug the charger into any 100-240 V AC outlet, flip the flat pins down, insert one battery, and wait for the LED to turn from red to green before removing it.

When will the two NB-6L batteries need replacing under normal use?

Expect the 1300 mAh cells to hold a useful charge for several hundred full cycles; swap them when shooting time drops noticeably below the original runtime.
