Questions about this item

Which Educator or Dogtra collar models accept this 30.20 x 18.24 x 7.20 mm lithium-polymer cell?

It replaces the original pack in Educator ET-300, ET-302, ET-400, ET-402 and EZ-900 through EZ-904 receivers, plus ME-300 transmitter and PE-900, PE-902, PE-903, RX-090 dog-collar units.

Will the original charger for my ET-400 or EZ-902 receiver charge this 3.7 V 300 mAh pack correctly?

Yes — the built-in decoded chip matches the factory voltage and capacity, so the stock charger delivers the same 3.7 V charge cycle without modification.

How can I confirm the battery is holding its rated 1.11 Wh after the first few charge cycles?

After two or three full charge-and-discharge cycles the collar should run its normal operating time; a sudden drop in run-time signals the pack is not performing to spec.
