It slots into the handset battery compartment and restores cordless operation when the original cell no longer holds a charge. No OEM part number is published for this model — match by handset model name before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePiana handset fit:\u003c\/strong\u003e\n    The Piana runs a 2.4V two-cell Ni-MH pack at a fixed voltage rail that the base station charger targets directly. The physical dimensions — 41.97 × 18.26 × 8.89mm — must clear the battery bay and connector tab. Confirm both before fitting.\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 2.4V Ni-MH test rig. The cell voltage rose steadily through charge without peaking early, and the BMS did not flag a false full-charge state. Capacity tracked within normal Ni-MH tolerance across the first three cycles.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the Piana base:\u003c\/strong\u003e\n    After fitting, seat the handset in the base and leave it for a full 16 hours before first use. Ni-MH cells shipped in partial-discharge state need a slow, uninterrupted first charge to reach rated capacity — a quick top-up will leave the pack short of 450mAh 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\"\u003eRange drop on the Piana after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that haven't completed conditioning cycles show a lower resting voltage than a fully formed cell. When the handset transmits, the RF circuit draws a short current spike that sags an undercharged pack's voltage below the transmit threshold. The phone responds by cutting transmit power, which reduces range. Run three to five full charge-discharge cycles and the resting voltage stabilises — range returns to normal once the pack holds above 2.2V under RF load.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station shows no-charge light after fitting new battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Piana base reads the incoming cell voltage to decide whether to begin a charge cycle. A new Ni-MH battery from storage can sit below 2.0V — low enough that the base rejects it as a fault rather than a flat pack. Reseat the handset firmly so both charge contacts close fully. If the error light persists, leave the handset docked for 30 minutes regardless — most Piana bases trickle at a low rate first, and the charge indicator only updates once the cell climbs above the acceptance threshold of approximately 2.1V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339978113114,"sku":"BWCS-ALT323CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339978145882,"sku":"BWCS-ALT323CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339978178650,"sku":"BWCS-ALT323CL-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALT323CL-1.webp?v=1778366983","url":"https:\/\/batteryweb.com\/products\/edisson-piana-replacement-battery-24v-450mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
