It powers the motorized air filtration and breathing assistance system in this medical-grade breathing apparatus. Voltage, connector, and BMS communication match the PA-A867-NG specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePA-A867-NG platform fit:\u003c\/strong\u003e\n    The PA-A867-NG runs a dedicated 9.6V Ni-MH rail with a multi-cell NiMH pack configuration. This replacement matches that cell count, connector pinout, and thermistor line so the device BMS recognises it without fault codes at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the PA-A867-NG's power-on self-test sequence and monitored BMS handshake across charge, discharge, and fault-detection routines. The pack passed charge termination and low-voltage cutoff within spec on all test runs.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After fitting this battery, allow the PA-A867-NG to complete its full power-on self-test without interruption. The device runs BMS verification at startup — cutting power during this sequence triggers a false battery fault that persists until the next full reboot cycle.\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 new PA000680 battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe PA-A867-NG BMS performs a chemistry verification check during boot. A new Ni-MH cell that has not completed its first full charge-discharge cycle may sit just below the BMS acceptance threshold, causing the boot sequence to stall or abort. This is not a fault with the battery — it is the device applying a conservative validation gate. Run one complete charge cycle to rated capacity before placing the unit into service, and the boot sequence will complete normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggers immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the BMS reads internal resistance on a new cell as higher than the OEM reference value, causing it to flag the pack before any real capacity is drawn. Ni-MH cells need one or two full charge-discharge cycles before internal resistance settles into the range the PA-A867-NG expects. The alarm clears once the BMS recalibrates against the cell's actual impedance. Complete a full discharge under normal operating load, then recharge to 100% — the alarm threshold resets at the end of that cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381410529370,"sku":"BWCS-PMA867MD-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381410562138,"sku":"BWCS-PMA867MD-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381410594906,"sku":"BWCS-PMA867MD-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PMA867MD-1.webp?v=1778900625","url":"https:\/\/batteryweb.com\/products\/pm-atemschutz-pa-a867-ng-replacement-battery-96v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
