It fits the DC-8300, DC-8500, DC-8600, and DC-X5. Dimensions are 41.95 × 36.05 × 9.80mm — match these before ordering if you are unsure which cell your body takes.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eTraveler DC-8300, DC-8500, DC-8600, DC-X5 fit:\u003c\/strong\u003e\n    These models share the same battery bay geometry and voltage rail, which is why one cell covers the group. The connector pinout and BMS communication protocol are identical across this series, so the cell seats and is read the same way in each body.\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 camera-class draw loads. The BMS held stable voltage delivery through sustained video capture and flash recharge draws without tripping the low-voltage cutoff prematurely.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-install charge cycle on Traveler bodies:\u003c\/strong\u003e\n    Insert the cell and run one full charge inside the camera body or OEM charger before shooting. Some Medion Traveler bodies need this cycle to map the new cell's discharge curve accurately — skipping it can cause the battery indicator to read incorrectly from the first shot.\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 erratically on the DC-8300 display\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe DC-8300's battery indicator maps voltage thresholds to percentage steps rather than tracking actual capacity directly. A new replacement cell has a slightly different discharge curve than the original, so the camera's lookup table can misread remaining charge — especially in the upper range. You will see large jumps, such as 80% dropping straight to 40%, in the first few cycles. After two or three full charge-discharge cycles inside the camera body, the indicator stabilises as the camera recalibrates against the real discharge profile.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eFlash not fully recycling between shots on a new cell\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThe flash capacitor draws a sharp current spike each time it recharges after firing. At the end of a cell's usable charge, internal resistance rises and the camera body limits current delivery to protect the circuit — slowing the recycle noticeably. If this happens early in a charge cycle on a new cell, the cell likely was not fully charged before use. Charge to 4.20V in the OEM charger, confirm the charge light turns green, then retest before assuming a fault.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333842894938,"sku":"BWCS-PRD8330-1","price":23.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333842927706,"sku":"BWCS-PRD8330-2","price":26.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333842960474,"sku":"BWCS-PRD8330-3","price":28.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-PRD8330-1.webp?v=1778213402","url":"https:\/\/batteryweb.com\/products\/medion-traveler-dc-8300-replacement-battery-37v-1250mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
