Questions about this item

Does the 4.8 V 750 mAh Ni-MH pack run hot or draw extra power during all-day use?

The 3.6 Wh Ni-MH chemistry delivers steady 4.8 V output with low self-discharge and built-in over-charge, over-discharge, over-voltage and short-circuit protection, so heat and power draw remain minimal during continuous operation.

What existing device or connector must I already have for this 650-052 battery to work?

It directly replaces the original Wetland 2000 SR200-IW, Uplandhunter SR-200IB, Sporthunter 1200 SR200-I, Sporthunter 1800 SR200-IM or Houndhunter SR200-I packs and matches part numbers 650-052, MH750PF64HC and DC-25.

Will this replacement pack fit and charge correctly in my older Sporthunter 1200 SR200-I collar?

Yes — the 48.87 × 34.05 × 12.49 mm dimensions and 4.8 V 750 mAh rating are made to the exact original specifications, so the legacy Sporthunter 1200 SR200-I accepts it without modification.
