It replaces OEM part 6MR2400SCY4C. The MSK15 is used in telecommunications and broadcast site surveys, where a failing battery interrupts logging sessions and measurement cycles in the field.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMSK15 and Golden Power measuring devices:\u003c\/strong\u003e\n    These instruments share the same 7.2V battery platform, connector pinout, and BMS handshake protocol. A single cell format covers both the MSK15 and compatible Golden Power units without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through probe initialisation events and sustained sensor logging loads. The BMS handled the initialisation current spike without tripping, and voltage held within tolerance across a full measurement session.\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 MSK15 instrument menu before field deployment. The instrument maps battery state during calibration — skipping this step causes premature low-battery warnings during the first measurement session, even on a fully charged pack.\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 MSK15 sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge over time. If the MSK15 has been stored for several months, the battery voltage can drop below the BMS recovery threshold. At that point, the BMS enters a protective sleep state and the instrument will not power on or accept a charge. The fix is to apply a slow, low-current charge for 30–60 minutes using a compatible external charger before attempting to power the device. Once voltage climbs above approximately 6.0V, the BMS re-initialises and normal charging resumes.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings resetting or drifting mid-session during sustained sensor logging\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the battery voltage sags under sustained sensor load — not a full shutdown, but a brief dropout that causes the MSK15 to reset its active measurement session. An aged or partially discharged pack is the usual cause, because Ni-MH voltage curves drop more steeply toward end of charge than the instrument's display threshold predicts. If you see mid-session resets with the battery indicator still showing charge, check resting voltage with a multimeter — anything below 6.8V under light load means the pack needs replacement before the next deployment.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360502120538,"sku":"BWCS-MKS150SL-1","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360502153306,"sku":"BWCS-MKS150SL-2","price":54.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360502186074,"sku":"BWCS-MKS150SL-3","price":60.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MKS150SL-1.webp?v=1778615883","url":"https:\/\/batteryweb.com\/products\/kathrein-msk15-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
