Has anyone found a hawks receiver battery replacement ? I have found some that are a little longer than the battery compartment but am trying to avoid modifying the case. Are there any batteries that fit ?
Sportdog battery SAC00-12542 will fit and work for transmitter and receiver.
If you separate the case there is lots of room for a larger battery. fasten in with two way tape or hot glue, you will probably have to cut the wires and solder on the original connector.
