It replaces OEM part number T415 directly. Voltage and capacity match the original specification exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTL900 fit:\u003c\/strong\u003e\n    The TL900 uses a 4.8V Ni-MH pack because its DAB decoder and RF front-end share a single regulated rail. Swapping to a different voltage or chemistry upsets that rail and causes tuning failures or cutouts mid-stream.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this pack through charge and discharge cycles on a DAB radio platform at 4.8V. The BMS held voltage within spec across the full discharge curve, and the radio maintained stream lock without dropout until the low-battery cutoff triggered cleanly.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-swap station scan:\u003c\/strong\u003e\n    After fitting this battery, run a full auto-scan before manual tuning. The TL900 stores its station list in volatile memory — any power interruption, including a battery swap, clears that list. A fresh auto-scan rebuilds it completely.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRadio cutting out mid-station at low battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe DAB decoder in the TL900 needs a stable voltage to reconstruct the OFDM signal continuously. When battery voltage sags under load, the decoder loses sync and the audio stream breaks up or drops entirely. This happens earlier in a degraded battery because internal resistance rises, causing larger voltage sags during the RF bursts. A fresh pack at full charge holds voltage above the 4.2V threshold where the decoder stays locked.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery drains faster in areas with weak DAB coverage\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eWhen DAB signal strength is low, the TL900's RF front-end draws more current as it works harder to resolve the multiplex. This increases the current load on the battery beyond what strong-signal listening demands. Users in fringe reception areas or indoors with poor antenna orientation will see noticeably shorter use between charges. Moving the radio to a window or extending any external antenna reduces the RF workload and lowers the drain rate.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360096387162,"sku":"BWCS-SLT900SL-1","price":29.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360096419930,"sku":"BWCS-SLT900SL-2","price":33.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360096452698,"sku":"BWCS-SLT900SL-3","price":36.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SLT900SL-1.webp?v=1778610878","url":"https:\/\/batteryweb.com\/products\/schaub-lorentz-tl900-replacement-battery-48v-2000mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
