It fits the BJ-UV22 VHF\/UHF transceiver used by ham radio operators and field communicators. Voltage and connector match the original pack exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBJ-UV22 platform fit:\u003c\/strong\u003e\n    The BJ-UV22 runs a 7.4V two-cell Li-ion pack with a direct rear-latch connection. This replacement matches that voltage rail and contact layout. The BMS in this pack communicates with the radio's charge circuit using the same handshake the original uses, so the radio accepts it without 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 BJ-UV22 body. The BMS held stable under repeated PTT draws and did not trip during sustained RF output. Voltage at full charge measured 8.37V open circuit, within spec for a two-cell Li-ion pack.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the BJ-UV22 charger dock:\u003c\/strong\u003e\n    If the charger dock shows a fault indicator on first insertion, remove the pack, wipe the contact strip with a dry cloth, and reseat it firmly. The dock requires a clean contact cycle to register the BMS signal 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\"\u003eBJ-UV22 cutting out mid-transmission on a new battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA new Li-ion pack ships at storage voltage — typically 3.7V to 3.85V per cell, not full charge. When PTT is pressed, transmit current spikes sharply. If the cell voltage is already low, that spike can pull the pack below the BMS overcurrent threshold, triggering a momentary cutoff. The radio interprets this as a power fault and drops the transmission. Charge the pack fully to 8.4V before the first field use to avoid this.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe BJ-UV22 uses a voltage-threshold bar indicator — each bar corresponds to a voltage band, not a percentage calculated by a chip. A new pack at storage voltage sits in the lower band and displays fewer bars even though the cells are not depleted. This is not a fault with the replacement pack. Run a full charge cycle first — the indicator will read correctly once the pack reaches 8.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426308522074,"sku":"BWCS-PUX328TW-1","price":32.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426308554842,"sku":"BWCS-PUX328TW-2","price":37.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426308587610,"sku":"BWCS-PUX328TW-3","price":41.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PUX328TW-1.webp?v=1779930681","url":"https:\/\/batteryweb.com\/products\/baojie-bjuv22-replacement-battery-74v-1200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
