It fits the 400P, 405P, 600P, and 605P series, along with 19 additional compatible models. OEM part numbers TOPB200, TOPB500, and TOPB800 are all covered by this pack.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e400P \/ 405P \/ 600P \/ 605P platform fit:\u003c\/strong\u003e\n    These models share the same 7.2V cell stack, contact layout, and BMS handshake protocol. One pack covers the full line 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 full charge and transmit-load cycles on a 400P unit. The BMS handled PTT current spikes without tripping, and the charger dock accepted the pack cleanly on first insertion.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst insertion on the GE dock:\u003c\/strong\u003e\n    If the dock shows a fault LED on first seat, remove the pack, wipe the contact strip with a dry cloth, and reseat firmly. The GE platform requires a clean contact surface to complete the BMS handshake before it will begin charging.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the GE 400P cuts out mid-transmission on a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eA fresh Ni-MH cell ships at storage voltage — typically 1.0–1.1V per cell, which puts this 6-cell pack around 6.2–6.6V at rest. When you key up, transmit current spikes sharply, and voltage sags further. The radio's undervoltage protection reads that sag as a low-battery condition and cuts TX before the pack is actually depleted. Running one full charge cycle before heavy use brings resting voltage up to the correct 7.2–7.5V range and eliminates this behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBar indicator showing one fewer bar than expected on a fresh pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe GE 400P uses a simple voltage-threshold bar display — each bar corresponds to a voltage band, not a measured capacity. A new pack at storage voltage sits below the top threshold, so the radio displays one bar short even though the cells are not depleted. This is not a fault with the pack. Charge it fully first — dock light goes solid green — then check the indicator again. A fully charged pack should read the top bar band at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43426347909210,"sku":"BWCS-TOX500TW-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43426347941978,"sku":"BWCS-TOX500TW-2","price":59.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43426347974746,"sku":"BWCS-TOX500TW-3","price":65.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TOX500TW-1.webp?v=1779930784","url":"https:\/\/batteryweb.com\/products\/ge-400p-replacement-battery-72v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
