Questions about this item

What voltage and capacity does the 4.8V 150mAh Ni-MH pack deliver?

The pack supplies 4.8 volts and 150 milliampere-hours, giving a total energy of 0.72 watt-hours.

Will the 31.3 by 21.56 by 11.04 millimetre, 40.4 gram pack fit my WetlandHunter SD-800 or SD-400 trainer?

Those dimensions and weight match the original DC-17, DC-17_5, 650-058, MH120AAAL4GC and 4SN-1/4AAA15H-H-JP1 packs used in the SD-800, SD-400 and SD-400S models.

How do I install the replacement pack, and what step do people often miss?

Open the transmitter battery door, unplug the old connector, insert the new pack with the same polarity, plug the connector in fully, close the door and charge fully before first use — skipping the initial full charge is the common mistake.
