It replaces an original cell that no longer holds charge or fails to power the device through a full playback session. Capacity is 1200mAh (1.44Wh) — matched to the OEM specification.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eVTE 1450M cell format:\u003c\/strong\u003e\n    This slim-profile cell measures 66.78 × 16.70 × 5.96mm, matching the narrow battery bay found in compact media players. The geometry matters — an oversized cell will physically bind before the contacts seat correctly.\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 a media player test rig. The BMS accepted charge current without interruption and held voltage above 1.0V through the full discharge curve before cutoff triggered.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst charge after installation:\u003c\/strong\u003e\n    Media players frequently enter a deep-discharge protection state after extended storage. Connect the charger and leave the device plugged in for at least 30 minutes before attempting to power on — this allows the trickle stage to recover the cell voltage above the BMS wake threshold.\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 a cell swap\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003ePortable media players estimate charge level by reading cell voltage against a fixed lookup table. A fresh Ni-MH cell has a slightly different discharge curve than an aged original, so the indicator recalibrates over the first few cycles. Expect erratic percentage readings for two to three full charge-discharge cycles. After that, the indicator stabilises as the firmware learns the new cell's voltage profile.\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\"\u003eAudio amplifier circuits draw a short current spike when driving headphones at higher volume. At the tail end of the discharge curve, Ni-MH cell voltage sags below 1.0V under that load — enough for the protection circuit to cut output even though the indicator still shows residual charge. The fix is to reduce playback volume during the last portion of the charge cycle. If cutout is immediate after installation, charge fully to 1.2V first before running the device.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43381333753946,"sku":"BWCS-VL700F6-1","price":20.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43381333786714,"sku":"BWCS-VL700F6-2","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43381333819482,"sku":"BWCS-VL700F6-3","price":25.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-VL700F6-1.webp?v=1778900030","url":"https:\/\/batteryweb.com\/products\/vapex-replacement-battery-12v-1200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
