It restores untethered operation for field diagnostics, signal tracing, and electronics troubleshooting away from AC power. Capacity figure is 4500mAh \/ 33.3Wh as listed in the product specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDSO-1062B \/ DSO-1202B \/ DSO-1202S compatibility:\u003c\/strong\u003e\n    These three models share the same 7.4V nominal voltage rail, identical PL727076 form factor (75.00 × 64.20 × 13.00mm), and the same BMS handshake protocol — swapping the pack across any of the three units requires no modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the DSO-1062B's charge circuit and monitored BMS cutoff thresholds under live probe load. The protection circuit tripped correctly at under-voltage and over-current limits without false shutdowns during signal acquisition.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration on the DSO-1062B:\u003c\/strong\u003e\n    After installing, run a full calibration cycle through the instrument's system menu before taking it into the field. 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 cutoff when the DSO-1062B probe inputs initialise\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eAt power-on, the DSO-1062B energises its front-end probe circuitry in a short burst that pulls a higher current than steady-state operation. A weakened or deeply discharged pack can't sustain that spike, and the BMS cuts output to protect the cells. The result looks like the unit powers up then immediately shuts off — not a display fault. Charge the replacement pack to at least 8.0V before the first boot to ensure the BMS stays latched through initialisation.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eVoltage sag causing readings to drift or reset mid-logging session\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDuring a sustained logging session, the oscilloscope draws steady current across both the display backlight and the acquisition circuitry simultaneously. If cell internal resistance has risen — common in packs that sat unused — voltage sags under that combined load and the instrument resets its timebase or drops data. This is a cell condition issue, not a firmware fault. Charge the new pack fully, then confirm resting voltage reads 8.3–8.4V before starting a long capture run.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360489898074,"sku":"BWCS-HDS106SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360489930842,"sku":"BWCS-HDS106SL-2","price":38.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360489963610,"sku":"BWCS-HDS106SL-3","price":42.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDS106SL-1.webp?v=1778615883","url":"https:\/\/batteryweb.com\/products\/hantek-dso-1062b-replacement-battery-74v-4500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
