It fits the LK4, LK6, LK8, and Light LK4 series remotes used to operate overhead cranes and industrial lifting equipment. Replaces OEM part numbers LBM02MH and ARB-LBM02M.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLK series transmitter fit:\u003c\/strong\u003e\n    The LK4, LK6, LK8, and Light LK4 remotes share the same battery bay dimensions and 2.4V NiMH power rail. The connector and cell configuration are identical across these units, so one replacement covers the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the bench under relay-activation loads. The BMS held steady through repeated solenoid-trigger events without dropping the voltage rail or tripping an overcurrent cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eInfrequent-use storage charge:\u003c\/strong\u003e\n    Autec crane remotes often sit idle for weeks between jobs. Charge this battery once a month during idle periods — NiMH cells self-discharge faster than Li-ion, and a cell left below 1.0V per cell for extended periods may not recover a full capacity cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSolenoid activation causing power dropout on the LK series remote\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a crane remote triggers a solenoid or contactor, it draws a short inrush current spike that can exceed what a low-capacity or partially discharged cell can deliver without a voltage sag. If the remote cuts out at the moment of activation, the battery is likely the cause — not the transmitter electronics. NiMH cells at end of life show a steeper voltage drop under load than a fresh cell at the same resting voltage. A new, fully charged 2000mAh cell handles these inrush events without triggering the remote's undervoltage cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote showing low battery indicator immediately after fitting a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eReplacement cells ship at storage voltage — typically around 1.0–1.1V per cell — not at full charge. The Autec remote reads this as a low battery state and flags it immediately on the display. This is not a fault with the battery or the remote. Place the battery on charge before first use and allow a full charge cycle to complete. The low battery indicator will clear once the cell reaches its nominal 2.4V under the remote's voltage threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360067977306,"sku":"BWCS-ALK400BL-1","price":28.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360068010074,"sku":"BWCS-ALK400BL-2","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360068042842,"sku":"BWCS-ALK400BL-3","price":35.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALK400BL-1.webp?v=1778610750","url":"https:\/\/batteryweb.com\/products\/autec-lk4-replacement-battery-24v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
