It replaces the original cell pack when capacity fades and the collar no longer holds a charge through a full training session. Dimensions are 48.87 x 34.05 x 12.49mm — verify these against your existing pack before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMH750PF64HC collar fit:\u003c\/strong\u003e\n    This battery matches the voltage rail and physical form factor of the MH750PF64HC collar. The 4.8V Ni-MH cell arrangement suits the low-current draw of training collar electronics — transmitter circuits and stimulus output are both sized for this chemistry.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a Ni-MH compatible charger and confirmed the BMS accepted full charge without thermal cutoff. Voltage at full charge measured within the expected range for a 4.8V Ni-MH pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap collar initialisation:\u003c\/strong\u003e\n    After fitting this battery, power the collar on and allow 60–90 seconds before pairing or testing stimulus output — the collar's microcontroller runs a brief self-check on first boot after a power interruption.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy Ni-MH cells in training collars lose capacity faster than the rated cycle count suggests\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells are sensitive to shallow cycling — repeated charges from 60–80% without a full discharge accelerate memory effect and reduce usable capacity over time. Training collars are especially prone to this because owners often top-charge after short sessions rather than running the pack down. The result is a battery that reads \"full\" but delivers noticeably less output after six to twelve months. Conditioning the new pack with two or three full discharge-and-recharge cycles before regular use helps establish accurate capacity from the start.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar shows charging indicator but voltage won't climb past 4.2V\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the charger is detecting current draw from a deeply discharged or faulty cell and shutting off early — not completing a full charge. A healthy 4-cell Ni-MH pack at full charge should sit at approximately 5.6V open-circuit. If the collar charger terminates early, try a standalone Ni-MH smart charger that uses delta-V detection rather than timer-based cutoff. Connect the new battery, confirm it reaches at least 5.4V before use, and re-seat it in the collar.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360189874266,"sku":"BWCS-SDC25SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360189907034,"sku":"BWCS-SDC25SL-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360189939802,"sku":"BWCS-SDC25SL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDC25SL-1.webp?v=1778610959","url":"https:\/\/batteryweb.com\/products\/kinetic-mh750pf64hc-replacement-battery-48v-750mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
