It powers the onboard SRAM and real-time clock when mains power is disconnected. Rated capacity is 1200mAh (4.32Wh) at 3.6V nominal.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eμGPCsH and μGPCsx compatibility:\u003c\/strong\u003e\n    Both controllers use the same backup cell footprint, voltage rail, and memory retention circuit. The 26.36 × 15.50 × 14.60mm form factor seats correctly in either unit without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We confirmed cell output at 3.6V nominal under low-drain SRAM hold conditions. The Li-SOCl2 chemistry delivers a flat discharge curve across its full capacity window, which is exactly what a memory retention circuit needs — voltage sag during backup hold is minimal.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap requirement on the μGPCsH:\u003c\/strong\u003e\n    Always replace this cell with the PLC powered on and in RUN mode. Removing the battery while the controller is powered off drains SRAM immediately. If that happens, the program is gone 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\"\u003eOn the μGPCsH, a battery alarm does not clear automatically once a new cell is fitted. The alarm flag is latched in the controller's status registers and must be reset manually through the programming software. Connect your programming device, navigate to the system diagnostics or status monitor, and clear the battery alarm flag explicitly. Until that step is done, the PLC will continue to report a battery fault regardless of actual cell voltage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eClock showing wrong date and time after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe real-time clock loses its reference the moment the backup cell is removed with the PLC powered off. Even a correctly installed new cell cannot restore the previous time — the RTC register is zeroed. After fitting the replacement battery, connect your programming device and set the date and time manually through the system clock configuration screen. Confirm the new value is written and the controller is back in RUN mode before disconnecting.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415973232730,"sku":"BWCS-MMC520SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415973265498,"sku":"BWCS-MMC520SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415973298266,"sku":"BWCS-MMC520SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-MMC520SL-1.webp?v=1779758775","url":"https:\/\/batteryweb.com\/products\/toyo-denki-%ce%bcgpcsh-replacement-battery-36v-1200mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
