It restores the voltage rail that drives both stimulation output and tone delivery. Capacity is 300mAh (2.16Wh) — matching OEM spec from the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMH330AAAK6HC collar fit:\u003c\/strong\u003e\n    This collar runs a fixed 7.2V Ni-MH cell stack. The BMS on the collar expects that specific voltage profile and cell chemistry for correct charge termination. Swapping to a different chemistry or voltage breaks that handshake and can trigger false full-charge signals.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the MH330AAAK6HC platform. The BMS accepted the charge curve without error flags, and stimulation output stayed within expected operating range across the full discharge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap collar reset:\u003c\/strong\u003e\n    After fitting this battery, power the collar off completely, wait 10 seconds, then power back on before placing it on the dog. The collar's internal circuitry re-initialises stimulation level calibration on a fresh boot — skipping this step can cause inconsistent output levels on first use.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MH330AAAK6HC collar shows full charge but cuts out during a training session\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells age by losing capacity, not by losing resting voltage. A worn cell can read 7.2V at rest but collapse under the current draw of a stimulation pulse. The collar's BMS sees the voltage drop as a fault and interrupts output. This is a cell-health failure, not a charger or receiver problem. Replacing the battery resolves it — the resting voltage on a fresh cell should hold above 7.0V under load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCollar not responding to the transmitter after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA full power interruption — such as a battery swap — clears the collar's active pairing state on some MH330AAAK6HC units. The collar needs to re-pair to the transmitter before it will accept commands. Power both the collar and transmitter off, then follow the pairing sequence in the manual starting from step one. Most units re-pair within 30 seconds and confirm with a beep or indicator light.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360186564698,"sku":"BWCS-SDC24SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360186597466,"sku":"BWCS-SDC24SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360186630234,"sku":"BWCS-SDC24SL-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDC24SL-1.webp?v=1778610959","url":"https:\/\/batteryweb.com\/products\/kinetic-mh330aaak6hc-replacement-battery-72v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
