It fits the PVM-2700, PVM-2701, PVM-2703, and related variants used in clinical vital signs monitoring. Capacity matches the original SB-201P specification exactly — 3800mAh (36.48Wh).\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePVM-2700 series compatibility:\u003c\/strong\u003e\n    These monitors share a common battery bay, connector pinout, and BMS handshake profile across the PVM-2700, PVM-2701, and PVM-2703. The 9.6V Ni-MH rail is fixed across the platform — swapping between variants requires no adapter or wiring change.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the PVM-2700 charge cycle and monitored BMS communication. The charge IC accepted the cell without fault codes, and the BMS reported state-of-charge correctly after one full charge-discharge conditioning cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test requirement:\u003c\/strong\u003e\n    After fitting this battery, allow the monitor to complete its full power-on self-test without interrupting the boot sequence. The PVM-2700 runs a BMS verification at startup — cutting power during this window 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\"\u003ePVM-2700 low battery alarm triggering immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe PVM-2700's BMS uses a learned capacity threshold calibrated to the previous cell's charge history. A new Ni-MH cell hasn't completed a BMS learn cycle, so the monitor compares its state-of-charge estimate against stale reference data and trips the alarm early. This is not a faulty battery. Run one full charge-discharge cycle — charge to completion on the monitor, allow normal use until the low battery warning appears, then recharge fully. After that cycle, the BMS recalibrates and the alarm threshold aligns to the new cell.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eMonitor will not power on after the replacement battery has been in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day in storage. If this battery sat unused for several months before installation, its resting voltage may have dropped below the PVM-2700's BMS recovery threshold — typically around 8.5V on a 9.6V pack. The BMS interprets this as a damaged or deeply discharged cell and blocks startup to protect the monitor's power circuitry. Connect the monitor to mains power and leave it on AC for at least 90 minutes before attempting a battery-only boot. The charge IC will trickle-charge the pack back above the recovery threshold, after which normal charging and BMS communication resume.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381499560026,"sku":"BWCS-NK2700MD-1","price":73.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381499592794,"sku":"BWCS-NK2700MD-2","price":86.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381499625562,"sku":"BWCS-NK2700MD-3","price":95.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NK2700MD-1.webp?v=1778901266","url":"https:\/\/batteryweb.com\/products\/nihon-kohden-pvm-2700-replacement-battery-96v-3800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
