It slots in where the original cell has degraded and no longer holds a charge through a full listening session.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTigerbox Touch and Radio Play Box compatibility:\u003c\/strong\u003e\n    These models share the same battery bay, connector pinout, and BMS handshake protocol. The 785273P part number covers all three variants — the voltage rail and physical footprint (74 × 52 × 9mm) are identical across the range.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through the Tigerbox Touch's charge controller and confirmed the BMS accepted the pack without a fault flag. Charge acceptance was normal, cell temperature stayed within the controller's threshold, and the fuel gauge registered correctly at both ends of the cycle.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge calibration tip:\u003c\/strong\u003e\n    The Tigerbox Touch fuel gauge drifts if the pack never fully discharges. Let the device play until it powers itself off — do this once a month — then charge to 100% without interruption. This recalibrates the gauge and keeps the charge indicator accurate.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eTigerbox Touch showing full charge but audio cuts out after an hour\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge has drifted after months of shallow cycling — the device reports 100% but the cell's actual capacity is a fraction of that. The Tigerbox Touch's BMS will hard-cut the output once cell voltage sags below its minimum threshold, even if the indicator still shows bars. A full discharge-to-shutdown followed by an uninterrupted charge to 100% is the first step. If the cutout persists after two of those cycles, the original cell has degraded past recovery and replacement is the fix.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eAudio distorting before the battery indicator reaches empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Tigerbox Touch's amplifier draws a sharp current spike at higher volume levels. As the cell ages and internal resistance rises, that spike causes a momentary voltage sag — the amplifier clips because it can't draw enough current cleanly, and you hear distortion before the battery indicator shows low. A fresh cell with lower internal resistance eliminates the sag. After fitting this replacement, confirm the issue is resolved by playing at full volume when the battery reads between 30–40%; if distortion is gone at that point, the old cell's resistance was the cause.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416197496922,"sku":"BWCS-TGB123SL-1","price":43.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416197529690,"sku":"BWCS-TGB123SL-2","price":51.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416197562458,"sku":"BWCS-TGB123SL-3","price":56.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-TGB123SL-1.webp?v=1779760792","url":"https:\/\/batteryweb.com\/products\/tigermedia-tigerbox-touch-replacement-battery-37v-3900mah-li-polymer","provider":"BatteryWeb","version":"1.0","type":"link"}
