Questions about this item

How do I fit the 105.00 x 57.80 x 25.00mm pack into the NX-200, and which step do people miss?

Align the three contacts with the camera’s terminals, slide the pack in until the latch clicks, then verify the 7.4V label faces outward; the missed step is skipping the latch check, which leaves the battery loose.

What upkeep will the 2500mAh Li-ion cell need over time?

Store at roughly half charge in a cool place if unused for weeks, recharge every few months to prevent deep discharge, and keep the contacts clean with a dry cloth.

What limit appears first when the TK-5320 draws continuous high current from the 18.50Wh pack?

Voltage sag under heavy load triggers the protection circuit, cutting power once the cell hits its lower safety threshold.
