It backs the PLC's SRAM, keeping program memory, tool offsets, and cutting parameters intact during power interruptions. Dimensions are 45.50 × 18.70 × 16.80mm — verify against the existing cell before installing.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eF148E15 and DR029 controller fit:\u003c\/strong\u003e\n    Both models share the same PLC backup circuit, CR8-LHC footprint, and 3V SRAM retention rail. One cell covers both configurations without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We confirmed stable float voltage delivery and verified the BMS handshake held the SRAM retention threshold under simulated power-loss conditions. No voltage drop or cutoff events were recorded during testing.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eCNC hot-swap procedure:\u003c\/strong\u003e\n    Always replace this cell with the controller powered on and in RUN mode. Removing the battery while the PLC is de-energised will immediately erase SRAM contents — program memory, axis parameters, and offsets will be lost and must be reloaded from a programming device.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePLC battery alarm not clearing after a confirmed good installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eInstalling a new cell does not automatically clear the battery alarm on the DR029 controller — the fault flag is latched in software and must be reset manually. Connect a programming device, navigate to the diagnostic or status register, and acknowledge the alarm through the controller's programming interface. Some configurations also require a counter reset if the cell-change interval log has not been updated. The alarm will stay active indefinitely until that step is completed, even with a fully charged cell seated correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew CR8-LHC cell reading below 3V immediately after installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-MnO2 cells ship at a storage voltage that can measure noticeably below the rated 3V — this is normal for the chemistry. Once seated in the PLC, the controller's float circuit brings the cell to operating voltage within a few hours. Do not replace the cell again based on a low initial reading. Recheck voltage at the battery terminals after four hours of powered operation — it should stabilise at or above 2.95V before the next maintenance window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415965302874,"sku":"BWCS-ODR029SL-1","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415965335642,"sku":"BWCS-ODR029SL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415965368410,"sku":"BWCS-ODR029SL-3","price":32.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ODR029SL-1.webp?v=1779758652","url":"https:\/\/batteryweb.com\/products\/onsrud-f148e15-cnc-machine-replacement-battery-3v-2200mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
