Direct replacement for training collars

The Estry battery matches the original SAC00-15724 pack used in WetlandHunter SD-400 CAMO, FieldTrainer SD-400S, FieldTrainer SD-400 and YardTrainer SD-350 units. It is a single Ni-MH cell rated at 7.2 volts and 120 milliampere-hours. The pack measures 31.1 by 22.6 by 15.9 millimetres and weighs 71.0 grams.

Voltage and chemistry must match

The device requires a 7.2-volt nickel-metal-hydride pack; using a different voltage or lithium chemistry will prevent the collar from operating correctly. Capacity is listed as 120 milliampere-hours in the specification table and 130 milliampere-hours in the highlights, delivering approximately 0.94 watt-hours. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Certified safety and ready to install

The battery carries ISO 9001, RoHS, CE, UN38.3 and MSDS certification, confirming compliance with quality and transport regulations. No additional cables, chargers or software are included in the package. Buyers who need a multi-pack or a different connector type should look elsewhere.

Questions about this item

How long will the 120 mAh capacity actually run my FieldTrainer SD-400 between charges?

The 120 mAh rating matches the original pack, so runtime should be identical to when the device was new.

Does the 7.2 V Ni-MH chemistry limit the charging method I can use?

Use only a charger designed for 7.2 V Ni-MH packs; the built-in protection circuit guards against overcharge, over-discharge and short circuits.

Will the 31.1 × 22.6 × 15.9 mm pack fit the battery compartment on my YardTrainer SD-350?

Yes — those are the exact dimensions of the original SAC00-15724 cell, so it seats without modification.
