It replaces OEM part numbers BAT-2000 and HXA-BAT-2000. Install this when the original cell no longer holds a charge or the device reports a persistent low-battery fault.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHBP-1300 and HBP-1320 compatibility:\u003c\/strong\u003e\n    Both models share the same battery bay geometry, voltage rail, and BMS handshake protocol. A single cell covers the full HBP-13xx series without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the HBP-1300's charge-discharge routine and confirmed the BMS accepted the new cell after one complete cycle. Charge acceptance was normal and the device cleared its low-battery flag at full charge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePower-on self-test after swap:\u003c\/strong\u003e\n    After fitting this cell, let the monitor complete its full startup self-test without interruption. The HBP-1300 runs a BMS verification sequence at power-on — cutting the sequence short triggers a false battery fault that sticks until the device reboots cleanly from a fully charged state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the HBP-1300 shows low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe HBP-1300's charge controller was calibrated to the OEM cell's internal resistance profile. A new replacement cell has a slightly different impedance signature on the first few cycles, which the BMS interprets as insufficient charge. This is not a fault with the cell — it is the BMS applying a conservative threshold against an uncalibrated pack. Run one full charge-to-discharge cycle and the BMS recalibrates its reference point. After that cycle, the low-battery alarm clears at the correct voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after the replacement cell sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge during storage, and the HBP-1300's BMS has a minimum recovery threshold around 3.0V. If the cell dropped below that threshold in the warehouse or in transit, the BMS blocks startup entirely as a protection measure. Connect the device to its charger for at least 30 minutes before attempting to power on — this brings the cell above the BMS recovery floor. If the monitor still does not start, leave it on charge for a full cycle and then press the power button again.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381506211930,"sku":"BWCS-OMP130MD-1","price":31.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381506244698,"sku":"BWCS-OMP130MD-2","price":36.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381506277466,"sku":"BWCS-OMP130MD-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-OMP130MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/omron-hbp-1300-replacement-battery-36v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
