It matches the OEM part number JHOTA-990-00 and fits the same battery bay without modification. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOIP-900 platform fit:\u003c\/strong\u003e\n    The OIP-900 uses an 11.1V three-cell Li-ion pack with a specific BMS handshake. This replacement carries the same cell configuration and connector pinout, so the pump's charge controller and BMS communicate without errors.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the OIP-900's charge cycle and monitored BMS communication at each stage. The protection circuit responded correctly to charge termination signals and the pump completed its startup self-test without triggering a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the OIP-900 complete its full power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this window causes 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\"\u003eWhy the OIP-900 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OIP-900's BMS uses a chemistry-calibrated threshold table to validate charge state. A new replacement cell has not yet completed a full charge-discharge learning cycle, so the BMS compares voltage curves against its OEM reference and flags a mismatch as low battery. This is not a fault with the cell — it is the BMS applying conservative validation logic to an uncalibrated pack. Run one complete charge-discharge cycle before clinical use and the alarm clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eOIP-900 will not power on after battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge during storage. If the pack voltage drops below the OIP-900's BMS recovery threshold — typically around 2.5V per cell, or 7.5V total — the protection circuit locks out and the device will not respond to the power button. Connect the pump to mains power and leave it on charge for at least 30 minutes before attempting to power on. The charger applies a low-current pre-charge recovery current to bring the pack above the lockout threshold before switching to full charge rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381418950746,"sku":"BWCS-SOP900MD-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381418983514,"sku":"BWCS-SOP900MD-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381419016282,"sku":"BWCS-SOP900MD-3","price":48.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SOP900MD-1.webp?v=1778900681","url":"https:\/\/batteryweb.com\/products\/osen-oip-900-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
