It fits the Philips Pronto TSU-9600 and TSU-9800 programmable touchscreen remotes. When the original cell degrades, the touchscreen dims, IR range drops, and the remote eventually stops responding — this swap restores full function.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTSU-9600 and TSU-9800 shared platform:\u003c\/strong\u003e\n    Both remotes run on the same internal battery bay, connector, and voltage rail. The PB9600 part number covers both units because Philips used the same cell across the platform revision — swapping to the TSU-9800 did not change the power architecture.\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 TSU-9600 platform. The BMS accepted the charge handshake cleanly and the touchscreen came up at full brightness without a reset cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eConnector seating on the TSU-9600:\u003c\/strong\u003e\n    The JST-style connector on this remote sits under a small retaining tab. Press the tab down before pulling the old connector — forcing it sideways cracks the tab and makes future swaps harder. Seat the new connector until it clicks.\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-9600 touchscreen goes dim before the remote stops responding entirely\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Pronto TSU-9600 backlight draws more current than the IR transmitter, so as the cell ages and internal resistance climbs, the touchscreen dims first while basic IR commands still fire. This makes it easy to underestimate how far the battery has degraded. By the time IR range drops noticeably, the cell is typically below 3.5V under load. Swap the battery at the first sign of consistent dimming — don't wait for the remote to stop transmitting.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTSU-9600 shows a charging indicator but won't power on after battery swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the new cell arrives below the BMS wake threshold — typically under 3.0V after extended shelf storage. The remote's charging circuit will still supply current, but the main board won't boot until the cell reaches approximately 3.2V. Leave it on charge for 20–30 minutes before attempting to power it on. If the charging indicator still won't appear, check that the connector is fully seated and the retaining tab has clicked into place.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416109711450,"sku":"BWCS-PSU9600RC-1","price":24.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416109744218,"sku":"BWCS-PSU9600RC-2","price":27.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416109776986,"sku":"BWCS-PSU9600RC-3","price":30.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PSU9600RC-1.webp?v=1779760330","url":"https:\/\/batteryweb.com\/products\/philips-pronto-tsu-9600-replacement-battery-37v-2200mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
