It also fits the 3111, BT8001, and SL82000 series. It restores the handset's ability to hold a charge when the original cell has degraded beyond use.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003e3101 \/ SL82000 platform fit:\u003c\/strong\u003e\n    These models share the same 2.4V two-cell NiMH pack format, connector pinout, and base station charge circuit. The 2SNAAA70H-SX2F cross-references directly to OEM part BT8001 and 89-1335-00, covering the full handset lineup without modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through the AT\u0026amp;T base station charge circuit and confirmed the NiMH acceptance voltage triggered correctly. The BMS-equivalent charge termination in the base responded to peak voltage detection without error or fault indication.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge conditioning on NiMH cordless handsets:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full 16 hours before first use. NiMH cells at storage charge won't reach rated capacity on a short first cycle — the slow initial charge lets each cell equalise and reach its full 700mAh rating.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station charge light not activating on a new NiMH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAT\u0026amp;T base stations on the 3101 and SL82000 series use delta-V detection to confirm a battery is present and accepting charge. A new NiMH pack sitting in warehouse storage can drop to a voltage the base reads as an open circuit or fault. The fix is to check the battery contacts on both the handset and base cradle for oxidation, then reseat the handset firmly. If the charge light still doesn't activate, measure the pack voltage — anything below 1.8V total may need a short external boost charge before the base circuit will engage.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange dropping mid-call after replacing the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets on this platform draw a current spike during each transmit burst. If the NiMH pack hasn't completed its first full conditioning cycle, internal resistance is higher than rated, and voltage sags under that RF load. The handset interprets the voltage drop as a low-battery condition and reduces transmit power, which cuts range noticeably. Run three to five full charge-and-use cycles through the base station to condition the cells — internal resistance drops after each cycle and transmit voltage stabilises.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43340050399322,"sku":"BWCS-UT3101CL-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43340050432090,"sku":"BWCS-UT3101CL-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43340050464858,"sku":"BWCS-UT3101CL-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-UT3101CL-1.webp?v=1778367047","url":"https:\/\/batteryweb.com\/products\/att-3101-replacement-battery-24v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
