It matches the OEM part numbers 11-0150 and MSP1437. The EPS is a portable medical suction device used for airway clearance and secretion removal in clinical and transport settings.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEPS Suction Pump compatibility:\u003c\/strong\u003e\n    The EPS platform runs a 12V Ni-MH architecture with a BMS that verifies cell chemistry at startup. This replacement matches that voltage rail and connector pinout exactly — the BMS handshake completes without error codes on installation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge-discharge cycles on an EPS unit and monitored BMS response at each stage. The protection circuit held cutoff correctly at both low-voltage and over-current thresholds throughout testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap startup protocol:\u003c\/strong\u003e\n    After installing this battery, allow the EPS to complete its full power-on self-test without interruption. Medical device BMS firmware runs a chemistry verification sequence at boot — cutting power mid-cycle trips a false battery fault that persists until the next complete reboot.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEPS Suction Pump alarming low battery with a freshly charged replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EPS BMS compares cell voltage against thresholds calibrated to a conditioned OEM cell. A new Ni-MH replacement starts with an uncharacterised voltage curve, so the BMS may flag it as low even after a full charge. This clears after one complete charge-discharge cycle, which lets the BMS map the actual capacity curve of the new cell. If the alarm persists past the second cycle, check that the charger reached 13.8V at termination before disconnecting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–2% per day. A cell stored for several months can drop below the BMS recovery threshold — typically under 10V for a 12V pack — causing the BMS to lock out the output entirely. Connect the battery to the OEM charger and leave it for a full charge cycle without interrupting it. Most EPS BMS controllers will re-initialise once the pack voltage climbs above 10.5V and resumes normal charge acceptance.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381412888666,"sku":"BWCS-SMP437MD-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381412921434,"sku":"BWCS-SMP437MD-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381412954202,"sku":"BWCS-SMP437MD-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SMP437MD-1.webp?v=1778900626","url":"https:\/\/batteryweb.com\/products\/mge-sam-eps-suction-pump-replacement-battery-12v-4500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
