It replaces OEM part numbers 5M702BMX, GP0827, GP0845, GP0735, GP0747, and GP0748. When the original pack no longer holds enough charge to sustain a call, this swap restores the handset to full operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVT1100 and VT2020 fit:\u003c\/strong\u003e\n    Both models share the same 2.4V two-cell NiMH pack format, connector pinout, and physical footprint — 35.40 × 32.50 × 6.70mm. One SKU covers both handsets 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 charge acceptance and discharge cycles on VT1100 hardware. The base station's charge circuit recognised the battery immediately, and the BMS held voltage within spec across the full discharge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge procedure for NiMH handsets:\u003c\/strong\u003e\n    After installing this pack, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cordless phone cells require a slow initial charge to reach rated capacity — pulling it off early will cut available talk time short.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than the original battery after replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells ship in a partially discharged state and require three to five full charge-discharge cycles before reaching rated capacity. The VT1100 base charges at a low trickle rate, so each conditioning cycle takes a full day. Do not judge capacity after the first charge. By cycle four or five, talk time should reach the 600mAh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light stays off or shows an error after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH packs that have sat in storage drop below the voltage threshold the base station's charge circuit expects to see. If the base does not register a charge attempt, remove the handset, wait 30 seconds, and re-seat it firmly. If the light still does not come on, measure the pack voltage — anything below 1.8V total will be rejected by the base until the cells recover slightly. A brief manual boost charge at 100mA for 15 minutes is enough to bring the pack above the acceptance threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340101288026,"sku":"BWCS-SDT500CL-1","price":21.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 2 Year","offer_id":43340101320794,"sku":"BWCS-SDT500CL-2","price":24.99,"currency_code":"USD","in_stock":false},{"title":"Warranty 3 Year","offer_id":43340101353562,"sku":"BWCS-SDT500CL-3","price":26.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDT500CL-1.webp?v=1778367188","url":"https:\/\/batteryweb.com\/products\/v-tech-vt1100-replacement-battery-24v-600mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
