It slots into the same housing as the original pack and connects to the same contact points. Use it when the original cell no longer holds a charge or the radio shuts down mid-use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDABMAN 12 compatibility:\u003c\/strong\u003e\n    The DABMAN 12 runs a single-cell 3.7V Li-ion architecture. This pack matches that voltage rail and physical footprint, so the BMS handshake initialises correctly on first insertion without any modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through transmit loads on a Li-ion test rig. The BMS held stable under the PTT current spike and recovered voltage cleanly after each transmit burst — no overcurrent trip was recorded at rated load.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip care on first insertion:\u003c\/strong\u003e\n    If the charger dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The dock requires a clean contact cycle to recognise the new BMS before charging begins.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the DABMAN 12 cuts out when PTT is pressed on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion cell ships at storage voltage — typically 3.6–3.7V, not a fully charged 4.2V. When PTT is pressed, the radio draws a short transmit current spike that can push the BMS below its low-voltage cutoff threshold if the cell is not yet charged. The radio interprets this as a depleted pack and shuts the transmitter down. Charge the battery fully in the dock before the first transmission to avoid this trip.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing fewer bars than expected after fitting the new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DABMAN 12 reads battery level through simple voltage thresholds — it has no fuel gauge chip. A new cell sitting at storage voltage of around 3.6V will register as one or two bars rather than full. This is not a fault with the replacement pack. Place the battery in the charger dock until the charge cycle completes and the indicator reaches a full charge voltage of approximately 4.2V, then reinsert — the bar display will reflect the actual charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426293284954,"sku":"BWCS-TMR446TW-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426293317722,"sku":"BWCS-TMR446TW-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426293350490,"sku":"BWCS-TMR446TW-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TMR446TW-1.webp?v=1779930602","url":"https:\/\/batteryweb.com\/products\/dabman-12-replacement-battery-37v-1100mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
