It fits the E7341031, E7341032, E7348036, E7348037, and four additional models in the same range. Voltage and cell count match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE7341031 and E7348036 series fit:\u003c\/strong\u003e\n    These models share the same 4.8V four-cell Ni-MH architecture, connector pinout, and LED driver input range. A single cell count or voltage mismatch will prevent the driver circuit from reaching full brightness — all models listed use this same pack format.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a Profilux LED light unit and confirmed the LED driver accepted the battery without fault, reaching full brightness output at rated voltage under continuous load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle LED driver calibration:\u003c\/strong\u003e\n    Run the light on medium brightness for the first full cycle. This lets the LED driver step up current gradually against the new cells before you push the pack to maximum draw, and it gives the Ni-MH chemistry a chance to reach full charge acceptance without voltage depression from the start.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLED work light dimming before the battery indicator shows low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells drop output voltage gradually under load, and LED drivers typically reduce drive current once cell voltage falls below the driver's minimum input threshold — which happens well before the battery indicator registers empty. This means the light dims noticeably while the indicator still shows charge remaining. It is not a fault with the battery or the driver. The indicator reads resting voltage, not loaded voltage. If dimming starts sooner than expected, check that the pack is fully charged before use — resting voltage should measure at or above 5.5V on a charged 4.8V Ni-MH pack.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLight not reaching full brightness after fitting a new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells often ship in a partially discharged state and may have slight voltage depression from storage. If the LED driver does not see sufficient input voltage, it will cap current output and the light runs below full brightness even with a brand-new pack installed. The fix is a full charge cycle before first use — do not skip this step with a new battery. After a complete charge, resting voltage across the pack should read between 5.5V and 5.8V, which is within the driver's normal operating window for full brightness output.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381320745050,"sku":"BWCS-KLE734SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381320777818,"sku":"BWCS-KLE734SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381320810586,"sku":"BWCS-KLE734SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-KLE734SL_1.webp?v=1778899964","url":"https:\/\/batteryweb.com\/products\/profilux-e7341031-replacement-battery-48v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
