It fits directly into the handset battery compartment using OEM part number 107733107. The 9.6Wh capacity matches the factory specification for this DECT phone series.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTranstalk 9030 and 9031 compatibility:\u003c\/strong\u003e\n    Both models share the same 4.8V four-cell NiMH pack, connector pinout, and charging circuit — the base station uses the same current and termination logic across the series, so one battery fits both handsets 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 9030 base station charging circuit and confirmed the BMS accepted charge termination at full capacity. Discharge curves held steady across the rated voltage window without premature cutoff.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the Transtalk base:\u003c\/strong\u003e\n    After installing, seat the handset in the base for a full 16-hour charge before first use. NiMH packs in DECT handsets ship partially discharged — skipping the slow first charge leaves cells unevenly conditioned and reduces available capacity from the start.\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\"\u003eNiMH cells don't reach rated capacity on the first cycle — it typically takes three to five full charge-discharge cycles to fully condition the pack. The Transtalk base uses a trickle-charge termination method that works best once cells have been cycled at least twice. If talk time is still noticeably short after five cycles, check that the handset is fully seated in the cradle contacts — a misaligned handset gets partial charge. Target resting voltage after a full charge should read approximately 5.6V across the pack terminals.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBase station showing a charging error or fault light on a new pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eNiMH batteries discharged below roughly 3.5V during storage can register as a fault on the Transtalk base charging circuit — the base expects a minimum voltage before it begins its charge cycle. Remove the handset, leave it out for 30 seconds, then reseat it firmly. If the fault light persists, the pack voltage may need a brief trickle boost — place the handset in the base, remove it after two minutes, then reseat it to prompt the base to restart the charge sequence. Most base stations accept the pack and begin normal charging within the second attempt.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339898388570,"sku":"BWCS-CPB499CL-1","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339898421338,"sku":"BWCS-CPB499CL-2","price":46.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339898454106,"sku":"BWCS-CPB499CL-3","price":51.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CPB499CL-1.webp?v=1778366906","url":"https:\/\/batteryweb.com\/products\/avaya-9030-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
