It matches the original cell dimensions at 52.98 × 35.59 × 7.16mm and slots directly into the existing battery bay. Voltage and capacity figures come from the product data — not estimated from web sources.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDiVi CAM 428 fit:\u003c\/strong\u003e\n    The DiVi CAM 428 uses a single-cell 3.7V Li-ion pack with a compact footprint. This replacement matches that form factor and the voltage rail the device's audio and media controller circuitry expects.\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 bench. The BMS engaged cleanly at both ends — no false low-voltage cutoff and no overcharge pass-through at the top of the charge curve.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after a cell swap:\u003c\/strong\u003e\n    Media players frequently enter deep-discharge protection after a new cell is fitted. Connect the charger and leave the device plugged in for at least 30 minutes before attempting to power it on — this allows the BMS to trickle-charge out of the protection state.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBattery percentage jumping after cell swap on the DiVi CAM 428\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eAfter fitting a new cell, the DiVi CAM 428's fuel gauge may report erratic percentages — jumping from 80% to 20% mid-session or skipping large chunks at a time. This happens because the device's voltage-threshold indicator was calibrated to the old, degraded cell's discharge curve. The new cell has a flatter discharge curve, so the voltage readings don't map cleanly to the stored thresholds. Run two or three full charge-to-cutoff cycles and the indicator recalibrates to the new cell's behaviour.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003ePlayback cutting out before the battery indicator shows empty\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe audio amplifier in the DiVi CAM 428 draws a higher instantaneous current than the idle display or menu navigation. Near the end of a discharge cycle, a tired or undersized cell cannot maintain the voltage rail under that load spike. The BMS reads the resulting voltage sag as a low-cell condition and cuts power — even though the reported charge still shows a few percent remaining. This replacement cell is rated to the original 1050mAh capacity, which restores the voltage headroom the amp needs in that final discharge window.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381344501850,"sku":"BWCS-CM428SL-1","price":22.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381344534618,"sku":"BWCS-CM428SL-2","price":25.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381344567386,"sku":"BWCS-CM428SL-3","price":27.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-CM428SL-1.webp?v=1778900058","url":"https:\/\/batteryweb.com\/products\/creative-divi-cam-428-portable-mp3-player-replacement-battery-37v-1050mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
