Direct replacement for SD-400 transmitters

This Estry Ni-MH pack matches the original 4.8V 150mAh specification for WetlandHunter SD-400 Camo and FieldTrainer SD-400S transmitters. It carries the SDT00-11907 part number and delivers 0.72Wh of energy. The cell measures 31.3 x 21.56 x 11.04mm and weighs 40.4g.

Simple two-wire swap with polarity care

Installation is a straightforward two-wire exchange inside the transmitter battery compartment. The main risk is reversing the connector polarity, which triggers the built-in short-circuit protection and prevents charging. Align the red and black leads exactly as the original pack was fitted and verify the connector seats fully before closing the cover.

Verify model and part number first

Confirm your transmitter is listed as SD-400, SD-400S or the WetlandHunter SD-400 Camo FieldTrainer and that the original battery carries part number SDT00-11907. Check that the existing pack dimensions match 31.3 x 21.56 x 11.04mm so the replacement fits the compartment. This pack is not suitable for devices requiring a different voltage, capacity or connector layout.
