It replaces the internal backup cell that powers the device when mains supply is interrupted. Fits both the MP-900F and the MP900F variant.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMP-900F and MP900F compatibility:\u003c\/strong\u003e\n    Both designations reference the same hardware platform. The voltage rail, terminal orientation, and physical footprint are identical across these labels — the difference is packaging region, not electronics.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through a full charge-discharge sequence and confirmed BMS handshake on the MP-900F platform. The charge IC accepted the cell without fault flags, and the low-battery threshold cleared after one complete cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap power-on sequence:\u003c\/strong\u003e\n    After installing this battery, let the device complete its full power-on self-test without interruption. The MP-900F runs a BMS verification routine at startup. Cutting power during this sequence triggers a false battery fault that sticks 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 MP-900F shows a battery fault after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MP-900F BMS stores a chemistry profile from the previous cell. When a new sealed lead-acid cell is installed, the BMS compares its internal resistance reading against that stored profile. A fresh cell reads differently than a broken-in one, so the fault triggers even though the cell is fully charged. Running one complete charge-discharge cycle lets the BMS update its profile. After that cycle, the fault clears and the device reports battery status correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice not completing boot sequence after the old battery sat discharged for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA sealed lead-acid cell that self-discharges below approximately 10.5V trips the MP-900F's under-voltage lockout. The device will not finish booting — it may reach the splash screen then cut off, or show no response at all. This is the BMS protecting the load, not a fault with the new battery. Connect the replacement cell and place the device on mains charge for a full charge cycle before attempting to power it on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381387559002,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381387591770,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381387624538,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/sunmind-mp-900f-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
