Questions about this item

What voltage does the 3.7 V lithium-polymer cell deliver to the ET-300 and ET-302 receiver circuits?

The battery supplies a nominal 3.7 volts, matching the original specification for ET-300-L, ET-300Receiver, ET-302Receiver and ET-402Receiver collars.

Will the 29.10 mm × 22.10 mm × 8.10 mm pack fit inside the ET-300-L transmitter housing?

Yes, the pack measures exactly 29.10 by 22.10 by 8.10 millimetres, the same footprint as the factory cell used in ET-300-L and ET-302-LTransmitter units.

Which step do installers most often miss when fitting the decoded chip into an ET-402Receiver collar?

After inserting the pack, the connector must be pressed fully home until it clicks; a loose seat keeps the protection circuit from enabling and the collar will not power on.
