It powers the vehicle's emergency supply module — the backup circuit that keeps critical safety functions active when the main 12V battery is depleted. Capacity is 1500mAh (4.8Wh) as specified for this application.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCamry VIII XV70 and RAV4 XA50 fitment:\u003c\/strong\u003e\n    Both platforms share the same 282A41872R emergency supply cell because Toyota uses an identical backup module and BMS handshake across the XV70 and XA50 chassis — same connector, same 3.2V LiFePO4 voltage rail, same charge termination protocol.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the module's charge-and-accept sequence and confirmed the BMS recognised the cell, completed charge termination cleanly at 3.65V, and released the emergency supply circuit for normal standby operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install initialisation:\u003c\/strong\u003e\n    After fitting, leave the vehicle on ACC or ignition-on for at least two hours so the module can complete its charge cycle. Until the cell reaches full charge, the emergency supply management system will not commit the battery to standby duty — do not rely on the backup circuit until the module indicator clears.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the emergency supply module shows a battery fault immediately after installation\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Toyota emergency supply module runs a firmware-controlled battery-check sequence every time a new cell is detected. This sequence takes up to two hours at a low trickle charge rate before the module logs the cell as accepted. During that window, a battery fault or warning light on the instrument cluster is normal — it does not indicate a faulty cell. The module checks internal resistance and open-circuit voltage before clearing the fault. Keep the ignition in ACC or start the vehicle and let it idle until the warning clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eEmergency supply not activating during a main battery failure after swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the emergency supply fails to activate during a main battery loss event after a cell replacement, the most common cause is that the new cell had not completed its first full charge cycle before the event occurred. LiFePO4 cells ship in a partial state of charge — typically 30–50% — and the module's BMS will not hand off to emergency power from a cell it has not yet fully accepted. Charge the cell to 3.65V through the vehicle's own charge circuit before testing the backup function. If the module still does not activate, check connector seating at the module harness before replacing the cell.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360428064858,"sku":"BWCS-FMK400SL-1","price":45.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360428097626,"sku":"BWCS-FMK400SL-2","price":53.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360428130394,"sku":"BWCS-FMK400SL-3","price":59.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FMK400SL-1.webp?v=1778614638","url":"https:\/\/batteryweb.com\/products\/toyota-camry-viii-xv70-replacement-battery-32v-1500mah-lifepo4","provider":"BatteryWeb","version":"1.0","type":"link"}
