It provides backup power during mains interruptions, keeping the device operational through brief outages. Capacity figures are drawn from product data — do not substitute web-sourced specs.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAS5 and AS2 platform compatibility:\u003c\/strong\u003e\n    These models share a common 12V SLA battery bay, connector orientation, and BMS charge acceptance profile. The same cell voltage and physical footprint (178 × 66.6 × 35mm) allows one battery to serve across this device family without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran a full charge cycle and confirmed charge acceptance, float voltage stabilisation, and BMS handshake. The battery held charge floor voltage under simulated load without triggering premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-installation self-test protocol:\u003c\/strong\u003e\n    After swapping this battery, allow the device to complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification sequence at startup — interrupting it causes a false battery fault flag that persists until the next complete reboot cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy new SLA cells fail the AS5B internal battery check on first install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe AS5B runs a BMS learn cycle during its initial charge after installation. A factory-fresh SLA cell has not yet been conditioned, so its internal resistance reading sits slightly above the OEM baseline the firmware expects. The device interprets this as a degraded or incorrect cell and flags a battery fault. One full charge-discharge cycle lowers internal resistance into the acceptable range. After that cycle, the battery check passes and the fault clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDevice will not power on after replacement battery sat in storage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSLA cells self-discharge at roughly 3–5% per month. A battery stored for several months before installation can drop below the BMS recovery threshold — typically around 10.5V for a 12V cell — which causes the device to refuse to boot rather than risk running on a critically low supply. Connect the device to mains power and leave it on charge for a full cycle before expecting the battery to carry a load. If voltage has dropped below 10V, some chargers will not initiate — use a standalone SLA charger set to recovery mode to bring it back above 11V first.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381388738650,"sku":"BWCS-SHT160MD-1","price":310.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381388771418,"sku":"BWCS-SHT160MD-2","price":370.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381388804186,"sku":"BWCS-SHT160MD-3","price":415.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SHT160MD-1.webp?v=1778900511","url":"https:\/\/batteryweb.com\/products\/baxter-as5b-replacement-battery-12v-2300mah-sealed-lead-acid","provider":"BatteryWeb","version":"1.0","type":"link"}
