It fits the BP-S510 directly using OEM part number 510-BAT. Use this when the original cell has degraded and the monitor can no longer sustain a full monitoring session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBP-S510 platform fit:\u003c\/strong\u003e\n    The Colin BP-S510 runs a 12V Ni-MH cell with a specific connector and BMS handshake tied to the 510-BAT part number. Swapping to a cell outside this spec triggers a persistent battery fault on boot — voltage rail and BMS communication both need to match.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the BP-S510's power-on self-test sequence and confirmed the BMS handshake cleared on the first full charge-discharge cycle. The cell held 12V under the monitor's continuous load profile without triggering a low-battery cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the BP-S510 complete its full power-on self-test without interruption. The device runs a BMS verification routine at startup — cutting power during this sequence causes a false battery fault that persists until the next full reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBP-S510 not completing boot sequence on a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Colin BP-S510 runs a BMS learn cycle on first use, and a new Ni-MH cell that hasn't been fully conditioned can fail this check. The device interprets an unconditioned cell as a faulty battery and halts the boot sequence. Run one complete charge-discharge cycle before placing the battery into clinical use. After that cycle, the BMS accepts the cell's actual capacity profile and the boot sequence completes normally.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBP-S510 alarming low battery immediately after a confirmed full charge\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis alarm fires when the BMS threshold is calibrated to an OEM cell that has been through multiple charge cycles — a new cell's voltage curve looks different on the first few cycles, and the monitor reads it as low. This is not a fault with the replacement cell. Run the battery through one full charge-discharge cycle on the monitor. After that, the voltage curve normalises and the low-battery alarm clears at the correct threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381464334426,"sku":"BWCS-PHM200MD-1","price":177.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381464367194,"sku":"BWCS-PHM200MD-2","price":207.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381464399962,"sku":"BWCS-PHM200MD-3","price":230.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHM200MD-1.webp?v=1778901015","url":"https:\/\/batteryweb.com\/products\/colin-bp-s510-replacement-battery-12v-4000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
