It slots into the handset compartment and restores charge capacity when the original cell no longer holds a full charge. No OEM part number is published for this pack — fit is confirmed by handset model and battery compartment dimensions.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eAscom Dream handset fit:\u003c\/strong\u003e\n    The Dream handset runs a 4.8V Ni-MH cell architecture. This pack matches that voltage rail and the compartment footprint (59.86 × 48.57 × 15.76mm), so the connector seats correctly and the base station's charge circuit sees the expected cell voltage.\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 4.8V Ni-MH test rig. The cell voltage climbed steadily to 5.6V at full charge, and the pack accepted a slow overnight charge without thermal rise or premature cutoff.\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 ship partially discharged, and skipping the slow initial charge means the pack will never reach its rated 1500mAh capacity in normal cycling.\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 the first few charges\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells do not reach full rated capacity on cycle one. The Dream's base station charges at a slow trickle rate, and a new pack typically needs three to five full charge-discharge cycles before the cells condition and hit 1500mAh. If talk time feels short after day one, that is normal — not a fault. Run the handset until the low-battery alert sounds, return it to the base for a full charge, and repeat. By cycle five, capacity should stabilise at rated output.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station not charging after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH packs often sit in storage and self-discharge to below 4.0V. Some base stations read a voltage that low as a fault and refuse to initiate a charge cycle — the charge indicator stays off or flashes an error. The fix is to briefly apply a top-up charge from a standalone Ni-MH charger set to 4.8V, bringing the pack above the base station's acceptance threshold. Once the pack is above roughly 4.4V, reseat it in the handset and place it on the base — the charge indicator should activate within two minutes.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339944362074,"sku":"BWCS-BT098CL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339944394842,"sku":"BWCS-BT098CL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339944427610,"sku":"BWCS-BT098CL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-BT098CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/ascom-dream-replacement-battery-48v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
