It maintains SRAM program memory and real-time clock data during main power loss. Voltage is 3.6V; capacity is 2000mAh (7.2Wh) as specified in the product data.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eER6V and ER14500 compatibility:\u003c\/strong\u003e\n    Both part numbers share the same AA-sized lithium cell format, 3.6V nominal voltage, and identical connector footprint used across Toshiba PLC backup battery holders. Either designation pulls the same cell from the same production run.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell under continuous SRAM float-charge load and confirmed the BMS holds stable voltage above the 3.0V SRAM retention threshold throughout the rated capacity window. No voltage sag under backup draw conditions.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eHot-swap procedure — critical for this controller:\u003c\/strong\u003e\n    Always replace this cell with the PLC powered on and in RUN mode. Removing the battery while the controller is off cuts SRAM supply instantly — program memory is gone and a full reload from the programming device is required.\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\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSRAM in these controllers has no capacitive hold — the moment battery voltage drops below roughly 3.0V, memory contents are erased. If the old cell was pulled with the PLC powered off, or if the swap took long enough for voltage to dip, the controller boots with a blank memory state. Reconnecting a good battery does not restore lost data. A full program reload via the programming terminal is the only recovery path.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery alarm not clearing after a confirmed good installation\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eToshiba and compatible PLC platforms latch the low-battery alarm flag in firmware — it does not auto-clear when a fresh cell is seated. The controller detects the new cell's voltage, but the alarm bit stays set until manually acknowledged. Open the programming software, navigate to the diagnostics or system flags register, and clear the battery alarm flag explicitly. Confirm the flag reads cleared before closing the session.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43415984472154,"sku":"BWCS-PLC145SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43415984504922,"sku":"BWCS-PLC145SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43415984537690,"sku":"BWCS-PLC145SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PLC145SL-1.webp?v=1779758955","url":"https:\/\/batteryweb.com\/products\/toshiba-er6v-replacement-battery-36v-2000mah-li-mno2","provider":"BatteryWeb","version":"1.0","type":"link"}
