Li-SOCl2 chemistry suits low-drain, long-interval field equipment where steady voltage under light load matters more than peak discharge. Direct replacement for OEM part numbers WILPA2119, KTT310RF, OSA465, and OSA464.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCF560 and Echo 2 platform fit:\u003c\/strong\u003e\n    These meters share the same form factor, connector pin-out, and voltage rail. The BMS handshake expects a 3.6V nominal cell with a flat discharge curve — exactly what Li-SOCl2 delivers across the operating range of field survey work.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through a simulated meter-read and RF transmission load. The BMS held steady through repeated short-burst RF polling events without tripping. Voltage stayed within the CF560's accepted window throughout the test.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install initialisation on CF560 units:\u003c\/strong\u003e\n    After fitting, trigger a manual meter read before field deployment. The CF560 maps battery state during its first active polling cycle — skipping this step causes the low-battery indicator to fire prematurely on the first field session, even with a fully charged cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBMS lockout after a CF560 sat unused in a carry case for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-SOCl2 cells develop a passivation layer on the anode during extended storage. When the CF560 tries to draw current from a passivated cell, internal resistance spikes briefly, and the BMS can interpret this as a fault and cut the circuit. The fix is a controlled depassivation: connect the battery and power the device on repeatedly in short bursts — three to five seconds on, ten seconds off — for several cycles. This bleeds off the passivation layer gradually and restores normal voltage delivery without triggering a lockout.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReadings drifting or logging session resetting mid-survey\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the cell voltage sags below the CF560's data-retention threshold under sustained sensor load during a logging session. An aged or deeply discharged Li-SOCl2 cell can show a healthy open-circuit voltage but collapse under the combined draw of the meter logic and RF module. Check open-circuit voltage first — it should sit at or above 3.5V. If the cell reads 3.5V at rest but the device resets under load, the cell's internal resistance has degraded beyond the instrument's tolerance and the pack needs replacement.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360460996698,"sku":"BWCS-ACF560SL-1","price":30.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360461029466,"sku":"BWCS-ACF560SL-2","price":35.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360461062234,"sku":"BWCS-ACF560SL-3","price":39.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ACF560SL-1.webp?v=1778615882","url":"https:\/\/batteryweb.com\/products\/actaris-cf560-replacement-battery-36v-5400mah-li-socl2","provider":"BatteryWeb","version":"1.0","type":"link"}
