It replaces the original pack when capacity has degraded to the point of shortened operating sessions or failed self-tests. The SSL-8000 is a medical illumination device used in surgical and dental procedures where consistent light output is non-negotiable.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSSL-8000 platform fit:\u003c\/strong\u003e\n    The SSL-8000 battery bay uses a fixed 14.4V nominal rail with a BMS handshake that checks cell voltage and temperature at power-on. This replacement cell matches those parameters so the system completes its startup sequence without throwing a battery fault.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge under a load profile matching the SSL-8000 drive circuit. The BMS cleared cell verification on the first full cycle and held the expected voltage curve through the full capacity window.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, allow the SSL-8000 to complete its full power-on self-test without interruption. Cutting power mid-sequence trips a false battery fault in the BMS that will persist until the unit completes a full, uninterrupted 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 SSL-8000 alarms low battery immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe SSL-8000's BMS holds a learned cell profile from the original pack. When a new cell goes in, the BMS compares its voltage-to-capacity curve against stored thresholds calibrated for an aged cell. A fresh cell at full charge can read outside that window and trigger a low-battery alarm even though the cell is genuinely full. Running one complete charge-discharge cycle lets the BMS update its reference data. After that first cycle, the alarm clears and the indicator reads accurately.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSSL-8000 not powering on after the battery sat in storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLithium-ion cells self-discharge during storage. If this battery sat in a warehouse or drawer long enough, cell voltage can drop below the SSL-8000's BMS recovery threshold — typically around 10V for a 14.4V nominal pack. Below that threshold, the BMS locks out power-on as a protection measure and the device shows no response at the power button. Place the battery on the charger and leave it for a full charge cycle without interrupting it. Most BMS units re-initialise and allow power-on once the cell returns above approximately 12V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381408956506,"sku":"BWCS-SND205MD-1","price":87.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381408989274,"sku":"BWCS-SND205MD-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381409022042,"sku":"BWCS-SND205MD-3","price":115.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SND205MD-1.webp?v=1778615901","url":"https:\/\/batteryweb.com\/products\/sunoptics-ssl-8000-replacement-battery-144v-3400mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
