It restores field-portable operation when AC power is unavailable. No OEM part number is published for this cell; fitment is confirmed by voltage rail, physical dimensions, and connector type.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDSO5014A and MSO6054A platform fit:\u003c\/strong\u003e\n    These models share the same 10.8V battery bay, connector pinout, and BMS communication protocol — one cell covers both scopes. The 148 × 89 × 20 mm form factor seats without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through the DSO5014A power-on sequence and monitored BMS handshake on the instrument's battery status screen. The BMS accepted the cell and reported charge state correctly after one full charge cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap self-test protocol:\u003c\/strong\u003e\n    After installing this battery, let the oscilloscope complete its full boot sequence without powering it off. The instrument runs a BMS verification pass at startup — cutting power mid-sequence causes the scope to log a 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\"\u003eWhy the DSO5014A shows a low-battery alarm immediately after a confirmed full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DSO5014A's charge IC applies a conservative acceptance threshold on cells it hasn't profiled yet. A freshly charged new battery can pass 4.1V per cell at the terminal and still trigger a low-battery warning on first boot. The BMS needs one complete charge-discharge cycle to calibrate its state-of-charge model against the actual cell chemistry. Run the scope until it shuts off on low battery, then charge fully — the alarm clears after that first cycle and does not return.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eScope won't power on after the battery sat in the case for several weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells self-discharge at roughly 2–3% per month, but the DSO5014A's BMS has a hard undervoltage lockout near 2.5V per cell — below that threshold it refuses to engage the power rail at all. A battery stored at partial charge for an extended period can drop below this floor. Connect the OEM charger and leave it for at least 90 minutes before attempting to power on; the charge IC uses a trickle recovery stage below 3.0V per cell that brings the pack back above the lockout threshold before switching to normal CC\/CV charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381507391578,"sku":"BWCS-PHM400MD-1","price":108.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381507424346,"sku":"BWCS-PHM400MD-2","price":128.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381507457114,"sku":"BWCS-PHM400MD-3","price":142.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PHM400MD-1.webp?v=1778901340","url":"https:\/\/batteryweb.com\/products\/agilent-dso5014a-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
