Battery or Something Else?

A battery that no longer holds a full charge is the usual cause of shrinking run time, but reduced range is more often a low charge or a damaged antenna than a failed cell. Work through troubleshooting common e-collar issues first, and read the charging and battery maintenance guide, sometimes it's the charging habit, not the battery.

Chargers & Car Chargers, a frayed cable mimics a dead battery
Antennas, if the symptom is lost range rather than lost run time
