It slots directly into the handset battery compartment and restores full wireless operation. Capacity is 2.52Wh — matched to the original spec.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTL1000 \/ TL1100 \/ TL1102 \/ TL1200A shared platform:\u003c\/strong\u003e\n    These four models run the same 3.6V single-cell Ni-MH pack with an identical connector and footprint — 45.60 × 31.30 × 10.60mm. The base station charges all four handsets at the same trickle rate, so one battery spec covers the whole line.\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 Ni-MH-compatible tester. The cell accepted a full charge without thermal runaway, and the terminal voltage held above 3.4V through the discharge curve — consistent with rated capacity.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-charge protocol for Ni-MH handsets:\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 shipped in a partial state of charge need that slow initial cycle to reach rated capacity — cutting it short will leave you with noticeably shorter talk time from day one.\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 or error light on a new Ni-MH pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAT\u0026amp;T Lucent base stations use a delta-V detection circuit to confirm charging. A new Ni-MH battery arriving from storage at a very low resting voltage — sometimes below 3.0V — can fall outside the window the base expects to see. The charger interprets this as a fault rather than a flat cell and stops the charge cycle early. Placing the handset in the base for at least 30 minutes, removing it, then reseating it usually allows the circuit to re-enter the charge phase once the cell voltage climbs slightly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRange drops noticeably mid-call after a battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eDECT handsets pull a short burst of RF transmit power during each voice packet — this creates a momentary current spike the battery must absorb without voltage sagging. If a Ni-MH cell hasn't been through at least three full charge-discharge cycles, its internal resistance is still elevated and the voltage dips under that RF load. The handset interprets the voltage sag as a weak signal and reduces transmit power, which cuts range. Run three full cycles — charge to completion, use the handset until the low-battery indicator shows, then recharge — and internal resistance drops to normal operating levels.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339964481626,"sku":"BWCS-CPJ464CL-1","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339964514394,"sku":"BWCS-CPJ464CL-2","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339964547162,"sku":"BWCS-CPJ464CL-3","price":31.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPJ464CL-1.webp?v=1777949695","url":"https:\/\/batteryweb.com\/products\/att-lucent-tl1000-replacement-battery-36v-700mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
