It slots into the original battery compartment and draws from the same two-cell pack configuration as the factory unit. Capacity is rated at 2200mAh — identical to the original specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eKraftwerk 32002 platform fit:\u003c\/strong\u003e\n    The 32002 runs a 7.4V two-cell Li-ion rail with a compact form factor — 65.53 × 36.48 × 18.15mm. The BMS on this pack monitors cell voltage balance and discharge cutoff at approximately 6.0V to protect the cells from over-discharge during extended illumination sessions.\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 the bench. The BMS held cutoff voltage within spec and balanced both cells within 20mV at full charge. No thermal events occurred across repeated charge cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eLight storage precaution:\u003c\/strong\u003e\n    If the lamp sits unused for more than four weeks, charge the battery before storing it — not after. A fully depleted Li-ion pack left in storage can drop below the charger's acceptance threshold, which prevents a normal charge cycle from initiating.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the 32002 charger blinks red and refuses a new pack after storage\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion chargers use a minimum acceptance voltage — typically around 2.5V per cell, or 5.0V for a two-cell 7.4V pack. If the pack has self-discharged below that threshold during storage, the charger's protection circuit flags it as a fault and will not enter normal CC\/CV charging. This is a charger-side safety feature, not a faulty battery. To recover the pack, some chargers support a trickle or recovery mode — check the 32002 charger manual for a \"recovery\" or \"soft-start\" setting. If that option is absent, a short 15–30 minute boost at a low rate from a compatible Li-ion charger can bring the cell voltage back above 5.0V and allow the original charger to accept it.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWork light dims noticeably mid-use even on a freshly charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA dimming LED output under load usually points to voltage sag caused by rising internal resistance in the cells. As Li-ion cells age or are repeatedly shallow-cycled, internal resistance climbs — the pack can measure 8.3V off-load but sag below 7.0V the moment the LED driver draws current. Check the battery contacts on both the pack and the lamp body for corrosion or debris, as poor contact resistance amplifies sag. If contacts are clean, the issue is cell degradation — replace the pack and verify the new pack holds above 7.2V under the LED load.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416070520922,"sku":"BWCS-BST200PW-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416070553690,"sku":"BWCS-BST200PW-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416070586458,"sku":"BWCS-BST200PW-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BST200PW-1.webp?v=1779760040","url":"https:\/\/batteryweb.com\/products\/kraftwerk-32002-led-akku-handlampe-replacement-battery-74v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
