It maintains SRAM memory in the programmable logic controller, holding machine parameters, configuration data, and program logic during mains power loss. When this cell depletes, the controller loses its backup power source and stored settings are at risk on the next power interruption.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDiana X115 PLC memory backup:\u003c\/strong\u003e\n    The Diana X115 controller relies on this cell to hold SRAM state when mains power drops. The 3V Li-MnO2 chemistry delivers a flat discharge curve that keeps retention voltage stable across the full cell life, avoiding the gradual voltage sag that causes silent memory corruption before a low-battery alarm triggers.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We loaded the cell against a controlled SRAM retention load, confirmed stable output at 3V, and verified the BMS protection circuit responded correctly to simulated end-of-discharge conditions. The cell held within spec across the full discharge profile.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap procedure on the Diana X115:\u003c\/strong\u003e\n    Always replace this battery with the PLC powered on and in RUN mode. Removing the cell while the controller is off will erase SRAM instantly — the backup supply disappears with no alternative path. If the swap happened during a power-off state, a full program reload from the programming device is required before the machine will run correctly.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePLC losing program memory after battery swap on the Diana X115\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Diana X115 controller holds its program and parameters in SRAM, which requires continuous voltage from the backup cell the moment mains power drops. If the old cell is removed while the controller is off — even briefly — SRAM loses power and the entire memory contents are erased. There is no internal capacitor bridge on this controller to cover a swap gap. After any power-off swap, the machine will either fail to start or run with corrupted parameters until the program is reloaded from the original programming device.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eNew cell installed but the battery alarm is still showing on the Diana X115\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA battery alarm on the Diana X115 PLC does not clear automatically when a new cell is fitted. The controller latches the alarm in software and it must be reset manually through the programming interface — fitting a new cell only removes the electrical cause, not the logged fault. Connect the programming device, navigate to the diagnostic or alarm log, and clear the battery fault flag. If the alarm returns within a short interval, check that the cell contacts are making firm contact and that the replacement cell reads at or above 3V at the terminals.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415967072346,"sku":"BWCS-HDX115SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415967105114,"sku":"BWCS-HDX115SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415967137882,"sku":"BWCS-HDX115SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HDX115SL-1.webp?v=1779758774","url":"https:\/\/batteryweb.com\/products\/heidelberg-diana-x115-replacement-battery-3v-1350mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
