It replaces OEM part numbers CLUB-1, INT-1, FAN-1, GP13AAH4BMX, GP22AAH4BMX, and B24. The pack measures 51.80 x 29.36 x 29.10mm and slots directly into the original battery compartment.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRange and Torch compatibility:\u003c\/strong\u003e\n    Both models share the same 4.8V four-cell Ni-MH configuration, connector pinout, and charge circuit. One battery pack covers both 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 charge and discharge on a Ni-MH compatible charger. The cells balanced correctly across all four, and the pack held voltage within expected Ni-MH discharge curves under sustained LED load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eMulti-cell replacement rule:\u003c\/strong\u003e\n    This pack contains four matched Ni-MH cells. If you are running two packs in rotation, do not mix cells or packs of different ages. An older cell in the string will drain first under high-current draw, causing reverse charging on that cell and permanent capacity loss.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlashlight dimming before battery shows low\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a relatively flat discharge curve, then voltage drops sharply near the end. The Clulite driver reads this voltage drop as a brownout and steps output down to protect the LED. This is normal behaviour — it is not a faulty battery. When dimming starts, the pack is near its cut-off voltage, typically around 4.0V for a four-cell Ni-MH string. Recharge promptly at that point to avoid deep discharge, which degrades Ni-MH capacity over repeated cycles.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery draining faster in turbo mode than expected\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eTurbo mode drives the LED at maximum current, which can draw five to ten times more current than the standard output mode. Ni-MH cells also lose effective capacity faster under high continuous current due to internal resistance heating. The result is noticeably shorter usable output compared to standard mode on the same charge. If you need extended use, switch to standard or medium mode — the pack delivers the same total energy, just over a longer period.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377520672858,"sku":"BWCS-CUB240FT-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377520705626,"sku":"BWCS-CUB240FT-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377520738394,"sku":"BWCS-CUB240FT-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CUB240FT-1.webp?v=1778767204","url":"https:\/\/batteryweb.com\/products\/clulite-range-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
