It slots into the handset battery compartment and restores cordless operation when the original pack no longer holds a charge. Confirm STB-914 on your existing battery label before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eSTB-914 handset compatibility:\u003c\/strong\u003e\n    AT\u0026amp;T grouped several cordless phone models around the same 3.6V Ni-MH cell format and connector. The STB-914 part number ties them to this specific pack — same voltage rail, same physical footprint, same connector orientation. If your handset originally shipped with STB-914, this battery matches that spec exactly.\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 cordless phone handset platform. The cell voltage came up cleanly from storage, the base station accepted the charge signal without error, and the pack reached rated capacity by the third full cycle — normal Ni-MH behaviour.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on 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 in cordless phones are slow-charged by the base — a rushed first charge cuts into how much capacity the pack develops over its early cycles.\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 do not deliver full rated capacity on the first cycle. The electrochemical structure needs three to five full charge-discharge cycles before the pack reaches 700mAh. If talk time feels short after the first day, run the handset down fully and recharge it completely — repeat that two more times. Capacity will increase noticeably with each cycle.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNi-MH packs drop to low resting voltage during storage — sometimes below the threshold the base uses to detect a valid battery. The base reads this as no battery present and withholds the charge current. Leave the handset seated in the base undisturbed for 30 to 60 minutes. The base will detect the rising cell voltage and switch the charge light on once it crosses approximately 3.0V.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339966185562,"sku":"BWCS-ALD180CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339966218330,"sku":"BWCS-ALD180CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339966251098,"sku":"BWCS-ALD180CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALD180CL-1.webp?v=1778366982","url":"https:\/\/batteryweb.com\/products\/att-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
