It fits the internal battery slot and restores power to the Bluetooth audio, pixel display, and alarm clock functions. Use this when the original cell no longer holds a charge or the unit stops powering on entirely.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTimebox power rail:\u003c\/strong\u003e\n    The Timebox runs its Bluetooth radio, LED matrix, and amplifier off a single 3.7V Li-ion cell. All three subsystems draw from the same rail simultaneously, so a degraded cell causes the whole unit to cut out — not just one function.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through full Bluetooth audio playback with the pixel display active. The BMS held voltage within the normal 3.0–4.2V window and did not trip under combined amplifier and radio draw at moderate volume.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFuel gauge reset after replacement:\u003c\/strong\u003e\n    After fitting this cell, run the Timebox down to the low-battery warning before the first recharge. Skipping this step causes the onboard fuel gauge to misread state-of-charge and report full when the cell is at 60%.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCapacity fade from constant desk-top charging on the Timebox\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe Timebox is often left plugged in on a desk, which means the cell spends most of its life sitting at 4.2V. Li-ion cells held continuously at full charge degrade faster than cells that cycle regularly between 20% and 80%. The BMS cannot compensate for this — it only protects against over-voltage and over-discharge, not chronic high-state-of-charge stress. To slow fade on this replacement cell, unplug once the indicator shows full and let the unit run on battery before topping off again.\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\"\u003eThis happens when the cell voltage sags below roughly 3.4V under the combined load of the amplifier and Bluetooth radio, even though the display still shows charge remaining. The amplifier clips because it is not receiving enough voltage to drive the output stage cleanly — the cell is effectively exhausted under load before the resting voltage drops enough to trigger the low-battery indicator. It is not a speaker fault. Fitting a fresh cell with full capacity resolves the clipping immediately. If distortion returns quickly after replacement, check that the USB cable is not still connected during playback, as charging and discharging simultaneously keeps the cell under continuous stress.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43416193466458,"sku":"BWCS-DVT100SL-1","price":205.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43416193499226,"sku":"BWCS-DVT100SL-2","price":245.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43416193531994,"sku":"BWCS-DVT100SL-3","price":275.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-DVT100SL-1.webp?v=1779760725","url":"https:\/\/batteryweb.com\/products\/divoom-timebox-replacement-battery-37v-2600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
