It replaces OEM part numbers GP1010 and VT50AAAALH2BMJZ. When the original pack stops holding a charge, this swap restores the handset to normal operation without buying a new phone.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDP500 and DP550 compatibility:\u003c\/strong\u003e\n    Both the standard and Eco Plus variants share the same handset chassis, connector pinout, and 2.4V NiMH cell configuration. One pack covers the full range of these models.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a DP500 handset. The BMS accepted charge from the base station immediately, and voltage held stable across the RF transmit load without triggering a low-battery cutoff during standby.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge protocol for NiMH handsets:\u003c\/strong\u003e\n    After fitting, seat the handset in the base and leave it there for a full 16 hours before the first call. NiMH cells from storage have reduced initial capacity — a slow first charge lets them reach rated 500mAh. Skip this and the first few talk sessions will feel 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 expected after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells ship partially discharged and need three to five full charge-discharge cycles before they reach rated capacity. If the first few uses feel short, that is not a fault — the cells are conditioning. Each full cycle gradually increases the usable capacity. By cycle four or five, talk time should match the original pack's rated performance.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not charging the new pack — error light stays on\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH packs that have sat in storage drop to very low resting voltages — sometimes below the threshold the base station's charge controller will accept. The base reads the low voltage as a fault rather than an empty cell. Remove the handset, leave it out of the base for 30 seconds, then re-seat it firmly. If the error persists, a trickle charge using a compatible external NiMH charger for 15 minutes will raise the cell voltage to approximately 1.0V per cell, which is enough for the base to recognise and resume charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339981979738,"sku":"BWCS-SDP500CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339982012506,"sku":"BWCS-SDP500CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339982045274,"sku":"BWCS-SDP500CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SDP500CL-1.webp?v=1778367002","url":"https:\/\/batteryweb.com\/products\/swissvoice-dp500-replacement-battery-24v-500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
