It fits the HSE5, HSE5ex, SEB8DIN, and SEB8LDIN models. The OEM part number is 31147000115 — verify this against your existing battery before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHSE5 and SEB8DIN series compatibility:\u003c\/strong\u003e\n    These four models share the same 4.8V cell configuration, connector pinout, and physical envelope. The SEB8DIN and SEB8LDIN are DIN-rail-mounted variants of the same emergency lighting platform — the battery pack is interchangeable across all four.\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 under a load representative of emergency flashlight draw. The BMS accepted charge without fault flags and delivered consistent voltage across the full discharge curve without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMulti-cell replacement rule for the HSE5:\u003c\/strong\u003e\n    The HSE5 runs a multi-cell pack. When one cell degrades, the others compensate — then fail faster. Replace the full pack rather than attempting single-cell substitution. Mixing a fresh pack with aged cells from a partially rebuilt unit creates immediate imbalance under high-current draw.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNi-CD memory effect in infrequently tested emergency flashlights\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eEmergency flashlights in standby applications are often topped up before they fully discharge — this is where Ni-CD memory effect accumulates. Over time, the cells learn a shallower capacity ceiling and begin cutting off well above true depletion. The HSE5 will still show a charged state but deliver noticeably reduced output under load. Running a full discharge cycle before recharge can partially recover capacity, but a pack showing this pattern consistently needs replacement.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHSE5 flashlight dims suddenly without the battery indicator triggering\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the pack voltage sags under load before the indicator threshold trips. The flashlight driver steps down output to protect the circuit — this is brownout protection, not a fault. The pack is depleted even though the indicator hasn't responded yet. Check open-circuit voltage: a healthy 4.8V Ni-CD pack should read 5.4–5.6V fully charged; anything below 4.6V at rest means the pack needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377507991642,"sku":"BWCS-BSE500FT-1","price":96.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377508024410,"sku":"BWCS-BSE500FT-2","price":112.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377508057178,"sku":"BWCS-BSE500FT-3","price":125.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BSE500FT-1.webp?v=1778767205","url":"https:\/\/batteryweb.com\/products\/ceag-hse5-replacement-battery-48v-5000mah-ni-cd","provider":"BatteryWeb","version":"1.0","type":"link"}
