It cross-references GP OEM part numbers GP0830, T304, and GP1033. It restores power to handsets that no longer hold charge or fail to leave the base station.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDECT handset compatibility:\u003c\/strong\u003e\n    Cordless phone handsets in this category share a common 2.4V two-cell Ni-MH pack format with a matched connector footprint and charge acceptance voltage. The base station charges via constant-current trickle at around 50mA — this pack meets that charge profile without triggering a charge fault.\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 a DECT handset platform. The BMS accepted charge from the base station on the first dock, and cell voltage stabilised across both cells within three conditioning cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\u003c\/strong\u003e\n    After installing, place the handset in the base for a full 16 hours before first use. Ni-MH packs shipped in partial-discharge storage state need a slow first charge to reach rated 500mAh capacity — skipping this step means the first few talk sessions will be noticeably shorter than expected.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no-charge or error light on a new Ni-MH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCordless phone bases use a delta-V detection circuit to confirm a Ni-MH pack is present and accepting charge. If the pack arrives from storage below roughly 2.0V total, the base may not recognise it as a valid battery and will show an error light or simply not charge. This is a voltage threshold issue, not a fault with the battery or base. To recover, hold the handset firmly in the base for 30–60 minutes — some bases will begin a slow trickle once the pack voltage climbs above the detection floor. If the base still shows an error after one hour, remove the handset, wait 10 seconds, and re-seat it to trigger a fresh detection cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping after battery swap — transmit cutting out at distance\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eCordless DECT handsets draw a sharp current spike when the RF transmitter fires — typically 150–300mA for a fraction of a second per burst. A Ni-MH pack that hasn't been fully conditioned has higher internal resistance, which causes the cell voltage to sag under that load. When voltage sags below the handset's transmit threshold, the RF output drops and range collapses. Run three full charge-and-use cycles on the handset before judging range — internal resistance falls with each cycle, and transmit voltage should stabilise above 2.2V under load by the third cycle.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339982078042,"sku":"BWCS-SPR6100CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339982110810,"sku":"BWCS-SPR6100CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339982143578,"sku":"BWCS-SPR6100CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SPR6100CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/gp-replacement-battery-24v-500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
