It restores power to portable clinical and personal-use electrotherapy units where the original cell has lost charge-holding capacity. Voltage and chemistry match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eA1B \/ MyStim \/ Musculaire Myo platform:\u003c\/strong\u003e\n    These models share a common 7.2V Ni-MH voltage rail and BMS handshake protocol. The battery connector and cell configuration are interchangeable across this cluster, which is why one replacement covers all four fit models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this battery through charge and discharge on compatible stimulator hardware. The BMS accepted the new cell, completed voltage verification, and held within expected tolerance across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eStartup self-test after swap:\u003c\/strong\u003e\n    After installing this battery, allow the device to complete its full power-on self-test without interruption. Medical-grade BMS firmware runs a voltage verification sequence at boot — cutting power during this window triggers a persistent battery fault that stays logged until the next clean reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence on a freshly installed battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe A1B and MyStim run a BMS learn cycle on first power-up with a new cell. If the resting voltage of the new battery sits near the lower end of the Ni-MH acceptance window after shipping and storage, the firmware can flag it as insufficient and halt the boot sequence. This is not a faulty battery — it is the charge IC applying a conservative threshold before it has mapped the cell's actual capacity. Charge the battery fully before first use and attempt boot again; resting voltage should read at or above 7.2V at the pack terminals before powering on.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eOn the first charge with a new Ni-MH cell, the device's charge IC applies a conservative current limit and may terminate early if delta-V detection fires prematurely on a fresh cell. This can leave the indicator showing 85–95% even after a full charge duration. Run one complete charge-discharge-charge cycle before relying on the indicator reading for clinical use — Ni-MH cells typically need two to three cycles before the charge IC accurately tracks actual cell capacity.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381495693402,"sku":"BWCS-CFA466MD-1","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381495726170,"sku":"BWCS-CFA466MD-2","price":41.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381495758938,"sku":"BWCS-CFA466MD-3","price":45.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CFA466MD-1.webp?v=1778901249","url":"https:\/\/batteryweb.com\/products\/stimulator-a1b-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
