It fits the TSU-9200, TSU9200\/37, and TSU920037 variants. The battery powers the remote's IR transmitter, touchscreen display, and onboard memory that stores device codes and macros.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTSU-9200 variant compatibility:\u003c\/strong\u003e\n    The TSU-9200, TSU9200\/37, and TSU920037 all use the same single-cell 3.7V Li-ion pack with OEM part number 2422 526 00193. They share the same connector pinout and BMS handshake, so one replacement covers all three variants.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We ran this cell on a TSU-9200 and confirmed the BMS accepted the charge cycle without triggering low-voltage lockout. IR transmission output held consistent across the full discharge curve above the cutoff threshold.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePronto memory retention during swap:\u003c\/strong\u003e\n    The TSU-9200 stores custom device configurations and macros in onboard flash memory. That data persists through a battery swap — you do not need to reprogram the remote after fitting this replacement.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the TSU-9200 touchscreen stays blank after a battery change\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eIf the screen does not light up after fitting a new cell, the BMS may have entered deep-discharge protection during the time the remote sat unused. The battery needs a trickle charge before the protection circuit resets and allows current to flow to the display. Place the remote on charge for at least 15 minutes before pressing any button. If the screen still does not respond, check that the connector is fully seated — the Pronto's battery bay connector can appear locked when it is still one click short.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eRemote needs to be held much closer to the TV after new battery install\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis usually means the cell is not delivering full voltage to the IR LED driver circuit. On the TSU-9200, the IR output stage drops off noticeably when supply voltage sags below around 3.5V. A brand-new Li-ion cell shipped in storage state may read as low as 3.2V out of the box. Charge the battery fully before use — the operating voltage needs to sit above 3.6V for the IR emitter to reach normal working range.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416102862938,"sku":"BWCS-PSU920RC-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416102895706,"sku":"BWCS-PSU920RC-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416102928474,"sku":"BWCS-PSU920RC-3","price":29.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PSU920RC-1.webp?v=1779760285","url":"https:\/\/batteryweb.com\/products\/philips-pronto-tsu-9200-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
