Direct replacement pack

This Estry Ni-MH battery pack delivers 4.8V and 150mAh capacity for Sport Trainer SD-400E, Wetland Hunter SD-400, Field Trainer SD-400, SD-400 and SD-350 models. It matches the original DC-17, DC-17_5, 650-058, MH120AAAL4GC and 4SN-1/4AAA15H-H-JP1 part numbers exactly. The cell measures 31.3 by 21.56 by 11.04mm and weighs 40.4g. It arrives new and ready to install.

Fits existing housing

The pack slides into the trainer’s original battery compartment without adapters or wiring changes. Built-in overcharge, over-discharge, over-voltage and short-circuit protection safeguards the electronics during charge cycles. RoHS, CE, ISO9001, UN38.3 and MSDS certifications confirm compliance with material and transport regulations. No extra hardware is required for the swap.

Steady output under load

The 0.72Wh rating supports consistent voltage delivery across the training session rather than a brief peak. Protection circuits prevent voltage sag when the collar transmitter draws peak current. Capacity holds through repeated charge cycles thanks to the ISO9001 quality process. The pack is not suited for devices that demand higher voltage or larger capacity than the original specification.

Questions about this item

How long does the 150mAh Ni-MH pack last during a full day of training with the SD-400?

The 150mAh capacity delivers 0.72Wh at 4.8V, so run-time depends on the collar's current draw; expect shorter sessions than higher-capacity packs.

Does the 40.4g battery get warm or make noise when the SD-350 runs continuously?

Ni-MH chemistry stays cool and silent during normal use; no fan or moving parts exist in this 31.3×21.56×11.04mm pack.

Which original part numbers must match for this pack to fit my Sport Trainer SD-400E?

Confirm your collar uses DC-17, DC-17_5, 650-058, MH120AAAL4GC or 4SN-1/4AAA15H-H-JP1 before ordering.
