It fits directly to the BodyGuard 323 using OEM part number 130-050X. Capacity is rated at 12.24Wh — matched to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBodyGuard 323 platform fit:\u003c\/strong\u003e\n    The BodyGuard 323 runs a proprietary BMS handshake that validates cell chemistry and voltage signature at power-on. This replacement matches the 7.2V Li-ion chemistry and connector pinout the BMS expects — no communication fault on startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the BodyGuard 323's power-on self-test sequence. The BMS completed charge verification without flagging a fault, and the device passed its internal diagnostics on first boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the BodyGuard 323 to complete its full power-on self-test without interruption. The BMS runs a cell verification routine at startup — cutting power during this window causes a latent battery fault that persists until the next clean reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the BodyGuard 323 alarms low battery with a freshly charged replacement installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BodyGuard 323's BMS is calibrated to OEM cell chemistry thresholds built from discharge curve data logged over multiple cycles. A new replacement cell hasn't yet established that curve history, so the BMS reads an unfamiliar voltage slope and flags it as a low-battery condition even when the cell is fully charged. This clears after the cell completes one full charge-discharge cycle, which allows the BMS to map the actual capacity profile. Run one complete cycle before placing the device back into clinical rotation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBodyGuard 323 not completing boot sequence after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the device stalls during its startup self-test after a swap, the most common cause is a cell that dropped below the BMS's recovery threshold during storage — typically below 6.0V for a 7.2V Li-ion pack. At that voltage the BMS blocks normal boot to prevent operation on a potentially compromised cell. Connect the device to its charger and allow a full charge cycle to complete before attempting to power on again. Once voltage recovers above the minimum threshold, the boot sequence completes normally.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381461549146,"sku":"BWCS-GRD323MD-1","price":65.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381461581914,"sku":"BWCS-GRD323MD-2","price":77.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381461614682,"sku":"BWCS-GRD323MD-3","price":86.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-GRD323MD-1.webp?v=1778900983","url":"https:\/\/batteryweb.com\/products\/cme-bodyguard-323-replacement-battery-72v-1700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
