It fits the handset directly, restoring wireless operation from the base station. Capacity is rated at 2.52Wh, matching the original pack specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eRAY2419 handset fit:\u003c\/strong\u003e\n    The RAY2419 uses a compact 3.6V Ni-MH cell pack with a specific footprint — 48.46 x 31.16 x 10.67mm. The connector and cell arrangement match the original so the handset battery compartment seats and contacts correctly.\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 bench rig. The BMS accepted charge from the base station without triggering a fault light, and voltage held stable through the RF transmit bursts typical of DECT operation.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH cordless packs:\u003c\/strong\u003e\n    Place the handset in the base immediately after installing this battery and leave it for a full 16 hours before first use. Ni-MH cells in cordless phones ship in a partially discharged state and need one slow charge cycle to reach rated capacity — skipping this reduces usable capacity from the start.\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 on a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells don't reach full rated capacity on the first charge cycle — or the second. The electrodes need three to five full charge-discharge cycles to activate fully. During this break-in period, talk time will be noticeably shorter than the original battery at its peak. Run the handset until the low-battery warning sounds, return it to the base for a full charge, and repeat this three to five times. By cycle five, capacity should stabilise at or near the 700mAh rating.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH batteries discharged during storage can drop below 3.0V — some base stations interpret this as a fault and refuse to begin charging. The fix is to seat the handset firmly in the base and leave it undisturbed for 30 minutes. Most RAY2419 base stations will trickle charge below the threshold voltage before switching to normal charge mode. If the error light persists after 30 minutes, remove and reseat the handset once, then confirm contact pins on both the handset and base are clean and fully touching.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340021629018,"sku":"BWCS-CPB1024-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340021661786,"sku":"BWCS-CPB1024-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340021694554,"sku":"BWCS-CPB1024-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB1024-1.webp?v=1778367024","url":"https:\/\/batteryweb.com\/products\/rayovac-ray2419-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
