It powers the wireless sensor heads and onboard display during live alignment sessions in automotive workshops. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCEMB DWA 1000 platform fit:\u003c\/strong\u003e\n    The DWA 1000 uses a 7.4V two-cell Li-ion architecture with a specific BMS handshake tied to the E-1080 form factor. This pack matches the cell configuration, connector pinout, and BMS communication protocol that the alignment unit expects on power-up.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through the DWA 1000's sensor initialisation sequence, which pulls a short high-current spike as the wireless sensor modules wake. The BMS held without tripping, and the unit moved cleanly through to the live measurement screen.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration cycle:\u003c\/strong\u003e\n    After fitting this battery, run a full calibration cycle from the DWA 1000's instrument menu before starting any alignment job. The system maps battery state during calibration — skipping this step causes premature low-battery warnings to appear during the first measurement session, even with a fully charged pack.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CEMB DWA 1000 cuts out when the sensor heads initialise\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen the DWA 1000 powers up its wireless sensor modules, there is a brief current surge as each sensor head negotiates its radio link and activates its internal gyro. An aged or partially discharged battery can't sustain voltage through this spike, and the BMS interprets the voltage sag as a fault condition and cuts output. This is not a fault with the alignment unit itself — it is a threshold response from the battery's protection circuit. A fresh pack at full charge holds the voltage rail steady through initialisation without triggering a cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eDWA 1000 not recognising new battery after pack sat unused\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf this battery has been stored for several months, the cell voltage may have dropped below the BMS recovery threshold — typically around 2.5V per cell, or 5.0V combined. At that level, the BMS enters sleep mode and the DWA 1000 may show no power response at all, or display a battery error, even when connected to the charger. Connect the pack to the OEM charger and leave it for at least 30 minutes without interruption — the charger applies a low-current recovery pulse that wakes the BMS before switching to normal charge current. If the charging indicator does not activate after 45 minutes, check that cell voltage at the battery terminals reads at least 5.5V before assuming the pack is unrecoverable.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360706953306,"sku":"BWCS-DWA100SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360706986074,"sku":"BWCS-DWA100SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360707018842,"sku":"BWCS-DWA100SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DWA100SL-1.webp?v=1778616209","url":"https:\/\/batteryweb.com\/products\/wheel-alignment-system-cemb-dwa-1000-replacement-battery-74v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
