It slots into the handset and restores power for portable calls around the home or office. Voltage and capacity match the original pack specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eMIAMI handset fit:\u003c\/strong\u003e\n    The MIAMI cordless phone uses a 4.8V Ni-MH cell pack with this specific form factor — 56.75 x 48.82 x 14.62mm. The connector orientation and cell arrangement match what the handset's charging circuit expects, so the base station reads the pack 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 the bench. The BMS held voltage across the full discharge curve without early cutoff, and the handset's charge indicator responded normally through each cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    After fitting this battery, seat the handset in the base and leave it for a full 16 hours before taking your first call. Ni-MH cells in cordless phones need this slow initial charge to reach rated capacity — skipping it shortens talk time 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 the original battery after replacement\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH cells don't deliver full rated capacity on the first cycle — or the second or third. The electrochemical pathways need three to five full charge-discharge cycles to reach 1800mAh. If talk time feels short straight after fitting, this is normal chemistry, not a faulty battery. Run the handset down to low battery and charge it fully in the base at least three times before judging capacity.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating with new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eA Ni-MH pack sitting in storage drops below the voltage level the base station expects to see before it begins charging. Some DECT base stations won't engage the charge circuit if the incoming voltage reads too low. Remove the handset, wait 10 seconds, then reseat it firmly — the base needs a clean contact signal to re-check the pack. If the light still won't activate, confirm the handset contacts and base cradle contacts are clean and making full contact.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339949113434,"sku":"BWCS-CPS486CL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339949146202,"sku":"BWCS-CPS486CL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339949178970,"sku":"BWCS-CPS486CL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPS486CL-1.webp?v=1778367002","url":"https:\/\/batteryweb.com\/products\/hanseatic-miami-replacement-battery-48v-1800mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
