It replaces OEM part SC1700HT in units that depend on sustained voltage delivery during power-loss events. Capacity is 1700mAh (10.2Wh) — confirmed from product data, not estimated.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEmergency lighting compatibility:\u003c\/strong\u003e\n    These packs share a 6V nominal rail and a standardised cell arrangement that most emergency lighting charge circuits expect. The BMS handshake on this pack aligns with charge controllers that monitor cell voltage rather than pack authentication codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on a 6V Ni-MH compatible charge controller. The BMS held cell balance across the full charge arc, and voltage stayed within the expected 6.0–7.2V window from trickle-in to top-off.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-use cycle for emergency packs:\u003c\/strong\u003e\n    Emergency lighting units often store a pack for months before the first real event. Run one full charge-discharge cycle immediately after installation so the charge controller builds an accurate capacity baseline against the new cells.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack running below rated voltage on first installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs ship at storage voltage — typically 5.4–5.8V rather than the 6V nominal. Emergency lighting units that check pack voltage at startup may flag a low-battery condition or refuse to switch to standby mode. This is not a fault with the pack. Connect the unit to mains power and allow a full charge cycle before testing. After charge, resting voltage should sit at 7.0–7.2V across the pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack not reaching full charge on the first cycle\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome emergency lighting charge ICs limit current on the first cycle when they detect a pack starting from storage voltage — they treat the low initial voltage as a sign of damage and throttle the charge rate. This clears after one full cycle. If the charge indicator still shows incomplete after a second cycle, check that the charge controller's delta-V cutoff threshold matches Ni-MH chemistry — some units default to NiCd settings, which terminate charge earlier.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333491359834,"sku":"BWCS-CM025SL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333491392602,"sku":"BWCS-CM025SL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333491425370,"sku":"BWCS-CM025SL-3","price":50.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CM025SL-1.webp?v=1778212805","url":"https:\/\/batteryweb.com\/products\/custom-battery-pack-replacement-battery-6v-1700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
