It replaces part number JHOTA-990-00 when the original cell degrades or fails. The OIP-900 is a compact clinical device, and this battery restores its portable operation without replacing the full unit.\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 JHOTA-990-00 uses an 11.1V three-cell configuration matched to the OIP-900's power rail and connector pinout. The BMS handshake is specific to this voltage profile — substituting a mismatched cell count triggers a protection fault at startup.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full charge-discharge cycle on this cell and confirmed the BMS communicated correctly with the charge IC. Capacity measured at rated spec and protection thresholds tripped at expected voltage limits.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test cycle:\u003c\/strong\u003e\n    After fitting this battery, allow the OIP-900 to complete its full power-on self-test without interruption. The device runs BMS verification at boot — cutting power mid-sequence registers 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\"\u003eDevice not completing boot sequence on new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe OIP-900 runs a BMS learn sequence on first boot with a new cell. If the battery voltage has dipped during storage, the device may stall mid-boot or display a battery error before the self-test completes. Charge the replacement fully before the first power-on — the charge IC applies a conservative limit on new cells, so the first charge may stop short of 100% on the indicator. A second full charge cycle typically resolves this and allows the boot sequence to complete normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLow battery alarm triggering on a freshly charged replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens because the OIP-900's BMS alarm threshold is calibrated against a characterised cell — a new replacement hasn't completed a learn cycle yet. The device treats an uncharacterised cell as suspect and fires the low-battery alarm even after a confirmed full charge. Run one complete charge-discharge cycle before clinical use. After that cycle, the BMS accepts the cell's capacity curve and the alarm clears at the correct threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381418655834,"sku":"BWCS-SOP900MD-1","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381418688602,"sku":"BWCS-SOP900MD-2","price":44.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381418721370,"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\/szosen-oip-900-replacement-battery-111v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
