It replaces the original pack when the unit loses charge capacity or stops holding power through a measurement session. Capacity is rated at 15.12Wh — use the figure from the product data, not the original label, for comparison.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHD Television and Satellite Analyser fit:\u003c\/strong\u003e\n    Both devices share the same 7.2V cell configuration, connector pinout, and BMS communication protocol — that is why one pack covers both. Swapping between platforms does not require a firmware change or battery reset on either unit.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran the pack through probe and signal-lock initialisation sequences on the Satellite Analyser. The BMS held the output rail steady through the current spike at probe power-up and did not trip cutoff during a sustained signal-scan cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use calibration on the Atom analyser:\u003c\/strong\u003e\n    After fitting this pack, run a full calibration cycle through the instrument menu before going to site. The Atom maps battery state during calibration — skipping this step causes the low-battery warning to fire early on the first active 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 Atom Satellite Analyser sat unused in a carry case for months\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs self-discharge continuously, even in storage. After several months in a carry case, the cell voltage can drop below the BMS recovery threshold — typically around 6.0V for a 7.2V pack — and the protection circuit locks out charging entirely. The instrument may power on briefly from residual charge and then shut off before the charger negotiates a connection. A slow pre-charge at low current, held for 15–20 minutes, is usually enough to bring the cells back above the recovery threshold and allow normal charging to resume.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or session data resetting mid-logging on the Satellite Analyser\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the Atom Satellite Analyser holds an active signal lock and logs data simultaneously, the sustained sensor and memory-write load pulls more current than idle operation. An aged or partially discharged Ni-MH pack can sag below the instrument's minimum operating voltage under that combined draw — not enough to shut the unit off cleanly, but enough to cause the processor to reset and wipe the active logging buffer. This is not a software fault. Check cell voltage under load with a multimeter — if it drops below 6.5V during a scan cycle, the pack needs replacing. Fitting a fresh 2100mAh cell and recalibrating through the instrument menu resolves the sag.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360662454362,"sku":"BWCS-RDS200SL-1","price":40.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360662487130,"sku":"BWCS-RDS200SL-2","price":47.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360662519898,"sku":"BWCS-RDS200SL-3","price":52.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RDS200SL-1.webp?v=1778616161","url":"https:\/\/batteryweb.com\/products\/atom-hd-television-replacement-battery-72v-2100mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
