It replaces OEM part numbers BL1703, BL2102, BH1801, BL1703Li, and BL-2102Li. The pack slots into the same battery bay and uses the same connector as the original HYT unit.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTC-700 and TC-780 platform fit:\u003c\/strong\u003e\n    Both the TC-700 and TC-780 lines share the same 7.2V battery rail, bay geometry, and contact layout. That common spec is why a single pack covers both model families without any adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the HYT standard charge dock and monitored BMS behaviour across transmit-current spikes. The protection circuit held stable during repeated PTT events and the pack accepted a full charge cycle without dock fault codes.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eContact strip condition before first dock insertion:\u003c\/strong\u003e\n    Ni-MH packs can leave microscopic residue on the gold contact strip during shipping. Wipe the contacts with a dry cloth before seating the pack in the dock. A single contaminated contact can prevent the dock from initiating the charge handshake and trigger a fault LED on the HYT charger.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TC-700 cuts out mid-transmission on a freshly inserted battery\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TC-700 draws a sharp current spike the moment PTT is pressed — transmit current can exceed standby draw by a factor of five or more. If the Ni-MH pack is still at storage voltage rather than a full charge, that spike can push the pack voltage below the BMS cutoff threshold in under a second. The radio interprets this as a depleted pack and drops the transmission. This is not a faulty battery — it is a cell that shipped at storage charge and has not yet been fully conditioned by a complete charge cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected after a full charge\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe TC-700 and TC-780 use a simple voltage-threshold bar indicator — each bar corresponds to a voltage band, not a calibrated fuel gauge. A new Ni-MH cell fresh off its first charge often sits slightly below its peak resting voltage while the cells stabilise. After one or two full discharge-and-charge cycles, the resting voltage rises into the correct band and the bar reading aligns. If the indicator still reads low after two full cycles, check that the charger completed a full green-light cycle and that pack resting voltage is at or above 7.8V before insertion.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426324316250,"sku":"BWCS-HTC710TW-1","price":48.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426324349018,"sku":"BWCS-HTC710TW-2","price":56.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426324381786,"sku":"BWCS-HTC710TW-3","price":62.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HTC710TW-1.webp?v=1779930634","url":"https:\/\/batteryweb.com\/products\/hyt-tc-700-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
