It fits the handheld applicator used for musculoskeletal pain relief and tissue healing in clinical and home settings. Swap it in when the original cell can no longer hold a charge through a full treatment session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePropex II applicator fit:\u003c\/strong\u003e\n    The Propex II runs a low-voltage 2.4V Ni-MH cell at this specific form factor — 44.80 x 20.80 x 11.42mm. The BMS handshake is calibrated to Ni-MH chemistry, so the charge IC and cell type must match exactly.\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 Propex II platform. The BMS accepted the cell, completed its verification routine, and the charge indicator advanced normally through the full charge sequence.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, let the Propex II complete its full power-on self-test without interruption. The device runs a BMS verification at startup — cutting power mid-sequence logs a false battery fault that persists 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\"\u003eWhy the Propex II reports a battery fault on a freshly installed cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Propex II BMS stores chemistry thresholds calibrated to the original OEM cell. A new replacement cell has not yet gone through a full charge-discharge learn cycle, so its internal resistance profile looks unfamiliar to the BMS. This can trigger a fault flag even when the cell is fully charged. One complete charge-discharge cycle allows the BMS to recalibrate its baseline and clear the fault. Do not use the device clinically until this first cycle is complete.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePropex II will not power on after the battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge over time. If a replacement battery has been sitting in storage, it may have dropped below the BMS recovery threshold — typically around 1.0V per cell — and the device will refuse to boot. Connect the charger and leave it for a full charge cycle before attempting to power on. If the charge indicator does not respond within 30 minutes, the cell voltage is likely below the charger's wake-up threshold; remove and reinsert the battery to prompt the charge IC to attempt a recovery charge.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381477769306,"sku":"BWCS-DSC210MD-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381477802074,"sku":"BWCS-DSC210MD-2","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381477834842,"sku":"BWCS-DSC210MD-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DSC210MD-1.webp?v=1778901051","url":"https:\/\/batteryweb.com\/products\/dssb-propex-ii-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
