It fits the Liberty C, Liberty CA, Liberty CLT4S, and Liberty S models. The BT153 part number matches the original battery these handsets shipped with.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLiberty series fit:\u003c\/strong\u003e\n    The Liberty C, CA, CLT4S, and S all use the same 4.8V three-cell Ni-MH pack with the BT153 footprint. Voltage rail, connector orientation, and physical dimensions are shared across the range — one part covers all four 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 cycles on the Liberty handset and confirmed the base station accepted charge without error. The BMS held cell balance across all three Ni-MH cells throughout cycling.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on Ni-MH cordless phones:\u003c\/strong\u003e\n    Place the handset in the base for a full 16 hours before first use. Ni-MH cells in cordless phones do not reach rated capacity on a short initial charge — the base station's trickle charge circuit needs the full window to condition the cells properly.\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  \u003cp class=\"bpw-desc-p\"\u003eNew Ni-MH cells ship in a partially discharged state and do not deliver rated capacity immediately. The Liberty handset's charge circuit uses a slow trickle rate, so the first few cycles will feel shorter than expected. Capacity builds progressively over three to five full charge-discharge cycles. By cycle five, the pack should reach close to the rated 1500mAh.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge or error light with new battery installed\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs that have sat in storage can drop below the voltage threshold the Liberty base expects before it starts charging. The base reads the pack voltage on contact — if it sees below roughly 3.6V across the cells, it may not initiate the charge cycle. Remove the handset, wait 10 seconds, and re-seat it firmly. If the error persists, a brief charge from a compatible external Ni-MH charger at 150mA for 15 minutes will bring the pack above the base acceptance threshold.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339943608410,"sku":"BWCS-BT098CL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339943641178,"sku":"BWCS-BT098CL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339943673946,"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\/aeg-liberty-c-replacement-battery-48v-1500mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
