It powers the vehicle's standalone siren sounder, which continues to activate even if the car's main battery is disconnected. Fits units referenced under OEM part numbers 12 762 811 and 52430010.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSAAB 93 siren alarm fitment:\u003c\/strong\u003e\n    The 93's siren module uses an internal backup cell so it can sound independently of the vehicle's 12V system. This cell matches the original's 4.8V four-cell configuration and connector footprint, keeping the module's charge circuit operating within its expected parameters.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the siren module's charge and activation circuit. The BMS accepted the cell without fault codes, and activation current held steady across multiple test triggers without voltage collapse.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eSiren cover latch after swap:\u003c\/strong\u003e\n    After fitting the new cell, close the siren housing fully and confirm the tamper switch is depressed by the cover. If the switch is not engaged, many alarm panels log a tamper event — and some interpret that as a battery fault rather than a cover fault.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the SAAB 93 siren activates briefly then cuts out\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA degraded siren cell may hold enough voltage at rest to pass the module's startup check, but collapses under the current draw of the sounder itself. The module then shuts off to protect its circuit, producing a short burst rather than a sustained alarm. A fresh 230mAh Ni-MH cell holds the voltage rail stable through the full activation cycle. If the siren still cuts short after fitting a new cell, check the charge line from the vehicle — the module needs a live feed to keep the backup cell topped up.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSiren not sounding during alarm test after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA newly fitted Ni-MH cell may arrive partially discharged — below the minimum threshold the siren module requires to trigger. The module's internal charger needs time to bring the cell up from a low state. Allow the vehicle to sit in alarm-ready mode for at least 24 hours before running a trigger test. If the siren still does not sound after that period, confirm the vehicle's ignition feed to the siren module is active and reading at least 12V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416137597018,"sku":"BWCS-AST811SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416137629786,"sku":"BWCS-AST811SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416137662554,"sku":"BWCS-AST811SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-AST811SL-1.webp?v=1779760424","url":"https:\/\/batteryweb.com\/products\/saab-93-siren-alarm-replacement-battery-48v-230mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
