These instruments are used for occupational safety monitoring in confined spaces, industrial sites, and emergency response — where a dead battery is not a minor inconvenience. Capacity matches the original M01-3053-000 specification at 13.32Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMultiRAE platform fit:\u003c\/strong\u003e\n    The MultiRAE Lite, MultiRAE, MultiRAE Pro, and MultiRAE Benzene all share the same battery bay geometry and 3.7V single-cell architecture. The BMS handshake and connector pinout are consistent across this platform, so one pack covers all four variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through full charge and discharge cycles on the MultiRAE platform, monitoring the BMS response during sensor initialisation — specifically the current spike when the electrochemical sensors come online at power-up. The BMS held within cutoff thresholds throughout.\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 through the instrument menu before field deployment. The MultiRAE maps battery state during calibration — skipping this step causes premature low-battery warnings during the first monitoring 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\"\u003eMultiRAE Lite shutting down mid-measurement with sensors active\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen all sensor slots are populated and actively polling, the combined draw from the electrochemical cells, PID lamp, and display can produce sustained current loads that a degraded or deeply discharged pack cannot sustain. The BMS interprets the resulting voltage sag as an undervoltage condition and cuts the output to protect the cells. This is not a fault in the battery — it is the BMS responding correctly to a real voltage drop. A fresh, fully charged pack at 4.1–4.2V at rest should carry this load without triggering the cutoff.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePack will not charge after the instrument sat unused for months\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eLi-ion cells left in a discharged state for an extended period will self-discharge below the BMS recovery threshold — typically under 2.5V per cell — and the protection circuit locks out to prevent charging a cell that may have degraded. The charger sees the pack as absent or faulty and stops. Some MultiRAE dock chargers include a recovery or wake mode; connect the pack and leave it on the dock for 15–30 minutes without interruption to allow the trickle-charge circuit to bring the cell back above 2.8V before the BMS re-enables full charging. If the cell voltage has fallen below 2.0V, the pack will not recover and needs replacing.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360456278106,"sku":"BWCS-PGM620SL-1","price":243.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360456310874,"sku":"BWCS-PGM620SL-2","price":291.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360456343642,"sku":"BWCS-PGM620SL-3","price":326.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PGM620SL-1.webp?v=1778615900","url":"https:\/\/batteryweb.com\/products\/rae-systems-multirae-lite-replacement-battery-37v-3600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
