It fits the portable SHS800X used for field service, signal analysis, and electrical troubleshooting. Capacity is sourced from the product specification — 47.52Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSHS800X platform fit:\u003c\/strong\u003e\n    The SHS800X shares a fixed voltage rail at 7.2V with a connector and BMS handshake specific to this handheld oscilloscope series. Any pack outside that voltage band will fail the instrument's power negotiation and refuse to boot.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through probe initialisation, active signal acquisition, and USB data transfer simultaneously. The BMS handled the combined draw without triggering a cutoff event, and charge acceptance was clean across all cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle through the SHS800X instrument menu before field deployment. The oscilloscope maps battery state during calibration — skipping this step causes premature low-battery warnings on the first measurement session.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after the SHS800X sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells in standby self-discharge slowly. If the SHS800X has been stored for several months without a charge top-up, the pack voltage can drop below the BMS recovery threshold — typically around 2.5V per cell. At that point the BMS enters a deep-sleep lockout and the instrument will not power on at all, even when connected to the charger. The fix is to apply a low-current recovery charge for 20–30 minutes before the BMS re-initialises and allows normal charging to resume. Once the pack reads above 3.0V per cell, normal charge cycles proceed without issue.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSHS800X display showing an inconsistent battery percentage after reboot\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new cell has a different discharge curve profile than the depleted original pack the instrument was calibrated against. The oscilloscope's fuel gauge reads voltage thresholds mapped to the old cell, so percentage jumps or reads low even when the battery is nearly full. This resolves after two to three full charge-discharge cycles, which allow the instrument's indicator to recalibrate against the new cell's actual curve. After cycling, charge the pack to full — confirmed at the charger LED going green — before trusting the on-screen percentage in the field.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360436453466,"sku":"BWCS-PRC057SL-1","price":176.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360436486234,"sku":"BWCS-PRC057SL-2","price":210.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360436519002,"sku":"BWCS-PRC057SL-3","price":236.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRC057SL-1.webp?v=1778614760","url":"https:\/\/batteryweb.com\/products\/siglent-shs800x-handheld-digital-oscilloscope-replacement-battery-72v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
