It maintains real-time clock and SRAM data when main power is removed. Rated at 2000mAh (7.2Wh), it matches the original cell dimensions at 53.30 × 16.10 × 14.90mm.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eYRC1000 controller fit:\u003c\/strong\u003e\n    The YRC1000 uses this cell specifically to hold RTC and volatile memory state during power-down events. The connector and cell format are matched to the controller's battery housing — no adapter or modification needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We confirmed open-circuit voltage on delivery, verified connector polarity, and checked that the cell holds stable voltage under the YRC1000's float charge circuit without triggering a battery alarm on reconnection.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap procedure for the YRC1000:\u003c\/strong\u003e\n    Always replace this cell with the controller powered on and in RUN mode. Removing the battery while the YRC1000 is powered off will cause SRAM loss — job programs, I\/O configuration, and RTC data will be erased 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\"\u003eWhy the YRC1000 battery alarm stays on after a confirmed good installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe YRC1000 does not automatically clear a battery alarm when a new cell is installed. The alarm is latched in the controller's fault log and requires a manual reset through the YRC1000 programming pendant or connected PC software. A fresh Li-MnO2 cell may also read slightly below 3.6V on first connection — this is normal for cells shipped in storage mode and does not indicate a fault. Once the controller's float charge circuit runs for several hours, voltage rises to rated level and the alarm can then be cleared cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eYRC1000 clock showing wrong date and time after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the old cell was removed while the controller was powered off, the RTC lost its reference entirely — installing a new cell restores the circuit but does not restore the time value. The controller will typically default to a reset timestamp, which can corrupt event logs and affect any time-triggered robot tasks. Set the correct date and time manually through the YRC1000 pendant under System → Clock settings immediately after the battery alarm is cleared. Confirm the RTC is holding time correctly by cycling controller power and rechecking the timestamp.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415960453210,"sku":"BWCS-YMC110SL-1","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415960485978,"sku":"BWCS-YMC110SL-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415960518746,"sku":"BWCS-YMC110SL-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-YMC110SL-1.webp?v=1779758652","url":"https:\/\/batteryweb.com\/products\/yaskawa-yrc1000-replacement-battery-36v-2000mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
