It replaces the internal insert-only cell that powers the pump during IV fluid and medication delivery. OEM part numbers OM11676, AS36296, S00273, and 55075-2 all cross to this unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSpectrum 35702 and 35724 compatibility:\u003c\/strong\u003e\n    Both models use the same insert-only battery bay, voltage rail, and BMS handshake protocol. The connector and cell dimensions — 70.50 x 50.90 x 10.60mm — match the original housing 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 Spectrum pump's charge-discharge sequence and confirmed the BMS accepted the cell, passed its internal verification, and held charge across multiple draw cycles without triggering a fault state.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After inserting the battery, let the pump complete its full power-on self-test without interruption. The BMS runs a chemistry verification routine at startup — cutting power mid-sequence flags a false battery fault that won't clear 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\"\u003eSpectrum pump not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Spectrum pump's BMS applies a strict verification window during boot. A new cell that hasn't completed its first full charge-discharge cycle may not hit the voltage threshold the BMS expects at startup. This causes the pump to stall mid-boot or display a battery error even when the cell reads charged. Run one complete charge cycle on the new battery before attempting clinical use — the BMS learn cycle sets the reference baseline the pump checks against on every subsequent boot.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCharge indicator not reaching 100% on the first charge after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Spectrum pump's charge IC applies a conservative current limit when it first encounters a new cell. This is normal behaviour — the charge controller hasn't established the cell's internal resistance profile yet and holds back to avoid overstress. The indicator typically stalls between 90–95% on the first charge. Run the pump through one full charge-discharge cycle and the charge IC recalibrates; subsequent charges reach 100% as expected.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381424226394,"sku":"BWCS-BAS351MD-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381424259162,"sku":"BWCS-BAS351MD-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381424291930,"sku":"BWCS-BAS351MD-3","price":38.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BAS351MD-1.webp?v=1778900661","url":"https:\/\/batteryweb.com\/products\/baxter-healthcare-spectrum-infusion-pump-35702-35724-pn-41049-insert-only-replacement-battery-74v-1800mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
