It slots directly into the handset battery compartment and restores talk time and standby performance lost to cell degradation in the original pack. Voltage and capacity match the factory specification at 3.6V and 4.32Wh.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBT2400 and GX2400 series compatibility:\u003c\/strong\u003e\n    These four models share a common 3.6V Ni-MH cell configuration, connector pinout, and physical footprint. One battery pack covers all four handsets 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 charge and discharge on the BT2400 platform. The BMS accepted charge current from the base station without fault, and voltage held stable across the RF transmit bursts typical of DECT handsets.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped in partial-discharge state need a slow, complete first charge to reach rated capacity — skipping this step will cause the first few cycles to read short.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange reduced on the GX2400 after a battery swap\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets regulate transmit power based on available voltage from the battery. When a new Ni-MH pack hasn't completed its first few conditioning cycles, voltage sags under RF load — specifically during the transmit bursts the handset fires to maintain the DECT link. The base station interprets this sag as a weak signal and the handset drops range earlier than expected. Running three to five full charge-discharge cycles brings cell voltage up to rated level and eliminates the sag.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no charge light after fitting the new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAudioVox base stations use a voltage threshold to confirm a battery is present and ready to accept charge. Ni-MH packs can sit in storage long enough for cell voltage to fall below that threshold — the base station then sees no valid battery and withholds charge current. To recover, remove the handset, wait 30 seconds, and re-seat it firmly. If the charge light still doesn't appear, confirm resting pack voltage is above 3.0V with a multimeter before concluding the base station has a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340023824474,"sku":"BWCS-P502CL-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340023857242,"sku":"BWCS-P502CL-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340023890010,"sku":"BWCS-P502CL-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-P502CL_1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/audiovox-bt2400-replacement-battery-36v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
