It fits the Active 6, Active 6 LMU Plus, BE B40, Transit 6 LMU, and several additional models in the same hardware family. Dimensions are 84.18 × 29.80 × 4.48mm — measure your existing cell before ordering if you are unsure of your variant.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eActive 6 family compatibility:\u003c\/strong\u003e\n    Becker's Active 6 line and Transit 6 variants share the same battery bay dimensions, connector pinout, and charge-management circuit. The SR3840100 part number spans all of these because the PCB charge controller is identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on a Becker Active 6 unit. The onboard charge IC accepted the cell without fault flags, voltage regulation held steady under display-on GPS-active load, and the protection circuit tripped correctly at the low-voltage cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst fix after installation:\u003c\/strong\u003e\n    After fitting this cell, power the navigator fully on outdoors before driving. A full power interruption triggers a cold start — the GPS receiver re-downloads almanac data and first satellite lock can take 5–10 minutes. Subsequent warm starts lock in under a minute.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eGPS accuracy dropping at low charge on the Active 6\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen cell voltage falls below roughly 3.5V under load, some Becker Active 6 units reduce GPS receiver sensitivity to protect remaining charge. The result is position drift or longer re-acquisition after tunnel exits. This is firmware-level power management, not a hardware fault. Keeping the battery above 3.6V during active navigation — via USB car charger — prevents the sensitivity reduction entirely.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eActive 6 shutting off without a low-battery warning\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe battery indicator on the Active 6 reads state-of-charge from a voltage curve calibrated to the original cell's age profile. A new cell has a flatter discharge curve than an aged one, so the indicator can read 20–30% and still trigger an immediate shutdown when load voltage sags under GPS + display demand. This is not a fault with the replacement cell. Discharge the new battery fully once, then charge to 100% to allow the firmware's voltage-to-percentage mapping to re-anchor to the new cell's curve.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43377586700378,"sku":"BWCS-BKE600SL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43377586733146,"sku":"BWCS-BKE600SL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43377586765914,"sku":"BWCS-BKE600SL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BKE600SL-1.webp?v=1778771730","url":"https:\/\/batteryweb.com\/products\/becker-active-6-replacement-battery-37v-1200mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
