It fits directly in place of part numbers PL903295 and CP-HLT71. When the original battery degrades, the receiver loses its ability to hold charge and can no longer operate away from mains power.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eHLT71 series compatibility:\u003c\/strong\u003e\n    The 805-01-NL, HERLT71, HLT71, and HLT71BAT all share the same 7.4V battery bay, connector pinout, and BMS handshake protocol — one pack covers the full range.\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 the HLT71 platform. The BMS responded correctly to cell voltage signals, with no false low-battery cutoffs observed at operating voltage.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install channel scan required:\u003c\/strong\u003e\n    After fitting the new battery, run a full DVB-T channel scan before watching. The receiver stores its channel list in volatile memory — a complete power removal wipes it, and the tuner will show no channels until a fresh scan completes.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eReception breaking up as the Haier HLT71 battery drains\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DVB-T tuner in the HLT71 series is sensitive to supply voltage. As battery voltage sags below roughly 6.8V, the tuner's RF front-end loses sensitivity and the signal-to-noise ratio drops. The decoder then struggles to lock onto weaker multiplexes, producing pixelation or freezing even when the signal meter still shows green. A fresh, fully charged pack brings the supply voltage back into the range where the tuner operates cleanly.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eSaved channel list gone after replacing the battery\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe 805-01-NL and HLT71 hold channel data in volatile memory that depends on continuous power. Pulling the old battery — even briefly — clears everything stored. This is normal behaviour, not a fault with the new pack. Once the replacement is seated and the receiver powers on, go to the menu and run an automatic channel scan to rebuild the full channel list.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43360230015066,"sku":"BWCS-HAT71TB-1","price":34.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43360230047834,"sku":"BWCS-HAT71TB-2","price":39.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43360230080602,"sku":"BWCS-HAT71TB-3","price":43.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-HAT71TB-1.webp?v=1778611023","url":"https:\/\/batteryweb.com\/products\/haier-805-01-nl-replacement-battery-74v-2500mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
