It uses OEM part number MLB-1000 and slots directly into the original battery compartment. Capacity is 1050mAh — identical to the factory specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMET-1000 and MET-1000-101-00 compatibility:\u003c\/strong\u003e\n    Both models share the same 3.7V voltage rail, connector footprint, and BMS handshake protocol, which is why a single cell pack covers the full MET-1000 platform without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge, standby, and transmit-load cycles on the MET-1000 platform. The BMS responded correctly to PTT current spikes and held cutoff thresholds within spec throughout each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check:\u003c\/strong\u003e\n    If the charger dock shows a fault LED after seating this pack, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The MET-1000 dock requires a clean contact cycle to complete the BMS handshake before charging will begin.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the MET-1000 cuts out mid-transmission on a new pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eWhen a Li-ion cell ships from a warehouse, it arrives at storage voltage — typically around 3.6–3.7V, not at a full charge state. The MET-1000's BMS monitors the voltage drop during PTT transmit bursts. If the cell isn't fully charged before first use, that voltage sag can cross the BMS low-voltage cutoff threshold mid-transmission, dropping audio or killing the TX entirely. This is not a faulty pack. Run a full charge cycle first — the dock green LED confirms completion — then retest transmission.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting MLB-1000\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe MET-1000 uses a voltage-threshold bar indicator, not a fuel gauge chip. A new cell at storage voltage reads lower than a freshly charged pack, so the radio displays fewer bars even though the cell is healthy. This is a voltage reading, not a capacity defect. Charge the pack fully — storage voltage sits near 3.65V, while a full charge pushes to 4.2V — and the bar indicator will reflect the correct charge state.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426368127066,"sku":"BWCS-FNB82TW-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426368159834,"sku":"BWCS-FNB82TW-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426368192602,"sku":"BWCS-FNB82TW-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-FNB82TW-1.webp?v=1779930808","url":"https:\/\/batteryweb.com\/products\/systemgear-met-1000-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
