It replaces OEM part 671487.009 when the original cell pack degrades and can no longer hold a charge adequate for emergency lighting duty. Capacity figure is taken directly from product data — 30Wh total energy.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEHSS platform fit:\u003c\/strong\u003e\n    The EHSS uses a multi-cell Ni-MH pack at 6V nominal. That voltage rail and the physical cell arrangement are fixed — this replacement matches both, so the driver circuit sees the same source impedance as the original pack.\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 Ni-MH compatible charger and monitored cell balance across the series string. The BMS held termination correctly at full charge, and no individual cell reversed polarity under load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMulti-cell replacement rule:\u003c\/strong\u003e\n    This pack contains multiple cells in series. If any original cells are left in place alongside new cells, the older, weaker cells will drain first. Under high-current draw that imbalance accelerates cell damage — replace the entire pack at once, never mix old and new cells.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlashlight output stepping down before the low-battery indicator activates\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe EHSS driver monitors pack voltage continuously. As the Ni-MH cells deplete, internal resistance rises and terminal voltage sags under load — often before the pack is truly empty. The driver interprets that voltage sag as an approaching cutoff and reduces output current to protect the cells. This is normal end-of-discharge behaviour in Ni-MH chemistry, not a fault with the replacement pack. If the step-down happens unusually early, check that pack voltage under load stays above 5.4V — drop below that and the driver will throttle output regardless of the indicator state.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlashlight won't hold charge after sitting unused for several weeks\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells self-discharge at roughly 1–3% per day at room temperature — a fully charged 6V pack left on a shelf for four to six weeks can lose enough charge to sit below the driver's minimum startup voltage. The light may appear dead even though the pack is not damaged. Connect the charger for a full cycle before concluding the pack has failed. If resting voltage reads below 5.0V after a complete charge cycle, the pack has not recovered and should be replaced.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377488986202,"sku":"BWCS-RLH671FT-1","price":78.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377489018970,"sku":"BWCS-RLH671FT-2","price":92.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377489051738,"sku":"BWCS-RLH671FT-3","price":102.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-RLH671FT-1.webp?v=1778767171","url":"https:\/\/batteryweb.com\/products\/rzb-leuchten-ehss-replacement-battery-6v-5000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
