Cameron Sino 300 mAh 3.7 V Replacement Battery for Educator Collar

Replacement Battery for Educator Collars

This 300 mAh 3.7 V lithium cell replaces the original power pack in a wide range of Educator training transmitters and receivers. It matches the BL-100, BP37TR, BP-504 and PL-711828 part numbers used across the 300, 400, 900 and EZ series collars. The pack measures 30.20 x 18.24 x 7.20 mm and weighs 6.5 g. A decoded chip ensures the collar recognises the battery exactly as the factory unit.

Physical Limits of the 30.20 x 18.24 x 7.20 mm

The rigid plastic shell fixes the maximum thickness at 7.20 mm, so the cell cannot fit compartments designed for slimmer packs. Its two-pin connector polarity is set for the Educator wiring harness; reversing the pins will prevent the collar from powering on. No alternative mounting tabs or cable lengths are provided, so the existing battery cavity must match the 30.20 x 18.24 mm footprint exactly.

300 mAh Capacity Decides Runtime per Charge

At 300 mAh and 1.11 Wh the pack delivers the same energy budget as the original cell, giving identical stimulation cycles between charges. Trainers running multiple daily sessions on a single collar will see no change in operating time. Buyers who need longer intervals between charges cannot meet that need with this replacement.
