It slots into the battery compartment to restore power to the light after the original cell has degraded or stopped holding charge. Capacity matches the original specification at 7.2Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePRO 138010 and Combi 138008 compatibility:\u003c\/strong\u003e\n    Both lights share the same 4.8V battery platform and physical form factor — 51.10 x 28.60 x 28.50mm — with the same connector orientation and voltage input to the LED driver board. One battery fits both.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell through charge and discharge cycles and confirmed the BMS held voltage above the LED driver's minimum input threshold throughout the usable discharge range. No premature cutoff was observed during standard operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst cycle on a new cell:\u003c\/strong\u003e\n    Run the light on medium brightness for the first full charge-discharge cycle. This lets the LED driver calibrate its current output against the new cell before you push it to maximum brightness — full output on an unconditioned Ni-MH cell can trigger an early voltage drop.\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 battery shows low\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells have a relatively flat discharge curve that drops sharply near end-of-charge. The LED driver in the PRO 138010 reduces current draw before the BMS reaches its cutoff threshold — this is intentional, not a fault. You will see the light step down in brightness while the indicator still shows charge remaining. This is the driver protecting itself from a hard voltage collapse, not a sign of a faulty battery.\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\"\u003eA new Ni-MH cell often ships in a partially discharged state. If the resting voltage is below the LED driver's minimum input — typically around 4.4V for a 4.8V pack — the driver cannot supply enough current to the LED array for full output. Fit the battery, connect the light to charge, and run a full charge cycle before first use. After charging, resting voltage should sit at or above 5.4V on a healthy cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381321531482,"sku":"BWCS-KLE734SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381321564250,"sku":"BWCS-KLE734SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381321597018,"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\/multiled-pro-138010-replacement-battery-48v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
