It replaces OEM part numbers LP043048AH, 253230694, and CTB104. When the original cell degrades, the handset loses the ability to hold a charge and stops working away from the base station — this battery restores wireless operation.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTHUB and CTB104 compatibility:\u003c\/strong\u003e\n    Both handsets use the same 3.7V single-cell Li-ion pack with the LP043048AH footprint — identical connector, BMS handshake, and 49 x 30 x 4.5mm form factor. No modification required.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge and discharge on the THUB platform. The BMS responded correctly to the base station's charge controller — no false full-charge cutoff, no trickle-charge refusal.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge on the THUB base station:\u003c\/strong\u003e\n    After installing, seat the handset in the base and leave it for a full charge cycle before using it. The THUB base delivers a low-current charge — interrupting it early on a new cell can cause the handset to underreport remaining capacity for several 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 expected after fitting a new Li-ion cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe THUB handset calibrates its fuel gauge against the previous cell's discharge curve. A fresh Li-ion pack has a different internal resistance profile, so the handset's charge indicator can read low even when the cell is not. Run two to three full charge and discharge cycles — the gauge resets itself against actual cell behaviour over those cycles. After that, talk time tracks correctly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eHandset loses DECT pairing after battery replacement\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eSome DECT handsets — including the THUB — store pairing data in volatile memory that clears when power drops to zero during a battery swap. Swapping the battery with the handset completely dead makes this more likely. After fitting the new cell, place the handset on the base for at least 30 minutes before attempting a call. If the handset still shows no line, re-register it manually: hold the Find Handset button on the base for five seconds while the handset is powered on.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43339930042458,"sku":"BWCS-CTB104CL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43339930075226,"sku":"BWCS-CTB104CL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43339930107994,"sku":"BWCS-CTB104CL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CTB104CL_1.webp?v=1778367002","url":"https:\/\/batteryweb.com\/products\/telstra-thub-replacement-battery-37v-700mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
