It replaces OEM part numbers AB700 and AB750. These radios are used in public safety, security, and industrial environments where a dead pack mid-shift is not an option.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eGH650, PH700, and PH790 compatibility:\u003c\/strong\u003e\n    All three models share the same battery bay dimensions, 7.4V rail, and BMS handshake protocol. One pack covers the full platform — no connector adapters or firmware flags needed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge acceptance, PTT transmit-current draw, and BMS cutoff verification. The protection circuit responded correctly to overcurrent spikes and recovered cleanly after simulated deep discharge.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-insertion contact check on the ZTE dock:\u003c\/strong\u003e\n    If the charger dock shows a fault LED on first seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The ZTE dock requires a clean contact surface to complete the BMS handshake before it will begin the charge cycle.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GH650 cuts out mid-transmission on a new AB700 pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003ePTT transmit pulls a sharp current spike — often two to three times the standby draw — in the first 200 milliseconds. A new cell shipped at storage voltage (typically 3.7–3.8V per cell) has less headroom to absorb that spike before the BMS interprets it as an overcurrent event and trips. The radio goes silent, then recovers in a second or two. Running one full charge-discharge cycle before field use brings both cells to rated capacity and eliminates the false trip.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after fitting a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe GH650 reads battery level by measuring terminal voltage against fixed thresholds — there is no fuel gauge chip. A new pack sitting at storage voltage reads lower than a fully charged one, so the radio displays one fewer bar than it should. This is not a faulty cell. Charge the pack to completion (the dock LED goes solid green), then power the radio on — the bar indicator will reflect the correct full-charge voltage of 8.4V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426206253146,"sku":"BWCS-ZPH700TW-1","price":64.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426206285914,"sku":"BWCS-ZPH700TW-2","price":76.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426206318682,"sku":"BWCS-ZPH700TW-3","price":85.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ZPH700TW-1.webp?v=1779930459","url":"https:\/\/batteryweb.com\/products\/zte-gh650-replacement-battery-74v-2000mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
