It replaces the original pack that powers the handset during calls and standby. Dimensions are 30.00 × 32.00 × 10.50mm — verify these match your handset bay before ordering.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBroad AT\u0026amp;T handset fit:\u003c\/strong\u003e\n    The 2422, 1165, 1177, and over 130 additional AT\u0026amp;T models share the same 3.6V single-cell NiMH form factor and battery contacts. One pack covers a wide range of AT\u0026amp;T cordless handsets from the same platform generation.\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 AT\u0026amp;T-platform handsets. The cell holds voltage through the transmit pulses without tripping the handset's low-battery cutoff at standard RF output.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on AT\u0026amp;T NiMH handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before the first call. NiMH cordless packs ship in a partially discharged state — the slow first charge lets the cells reach rated capacity. Skipping this step shortens usable charge for the first several cycles.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing no charge light after installing a new NiMH pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH cells lose voltage during warehouse storage. If the pack voltage drops below the base station's acceptance threshold — typically around 3.0V for a 3.6V NiMH — the base may not register a charge connection at all. The fix is to leave the handset seated in the base undisturbed for at least two to four hours. Most AT\u0026amp;T base stations will begin trickle-charging a deeply discharged pack once the circuit detects minimal cell resistance, and the charge indicator should appear within that window.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTalk time shorter than expected after the swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eShort talk time in the first few cycles after a NiMH swap is a chemistry issue, not a defective pack. NiMH cells need three to five full charge-discharge cycles before they reach rated capacity — 300mAh in this case. Each cycle, the pack holds a little more charge than the last. Run the handset down until the low-battery alert sounds, then return it to the base for a full charge, and repeat this for at least three cycles before judging talk time.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340004589658,"sku":"BWCS-ALM590CL-1","price":21.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340004622426,"sku":"BWCS-ALM590CL-2","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340004655194,"sku":"BWCS-ALM590CL-3","price":26.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-ALM590CL-1.webp?v=1778367023","url":"https:\/\/batteryweb.com\/products\/att-2422-replacement-battery-36v-300mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
