Cell degradation is the primary failure on these 1990s units — original packs lose capacity after years of partial cycling and long-term storage. Capacity is rated at 25.2Wh and matches the OEM voltage rail exactly.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eCVL-series camcorder compatibility:\u003c\/strong\u003e\n    The CVL-345, CVL-610, CVL-612, and CVL-620 share the same battery bay dimensions and 6V nominal voltage requirement. Connector orientation and cell count are identical across this model run, so one pack covers the full group.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this pack through charge and discharge on CVL-series hardware. The battery accepted a full charge without thermal event, and the camcorder's low-battery indicator triggered at the expected voltage threshold near 5.4V.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eFirst-cycle conditioning on Ni-MH:\u003c\/strong\u003e\n    Ni-MH cells in long-stored camcorders can show false low-battery warnings on a fresh pack if the charger hasn't calibrated to the new cell's internal resistance. Run one complete charge-to-full cycle using the OEM Magnavox charger or camera body charger before shooting — this lets the charge circuit map correctly to the new cell.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eWhy the CVL-345 reports low battery on a fully charged replacement pack\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe CVL-series charge indicator reads voltage, not true state of charge. A new Ni-MH cell has a flatter discharge curve than a worn original, so the camcorder's voltage thresholds can misread a charged cell as partially depleted. The fix is straightforward: charge the new pack to 100% in the OEM charger, then leave it seated in the camera body for 10–15 minutes before powering on. This gives the circuit time to sample resting voltage and recalibrate its display. After one full use-and-recharge cycle, the indicator typically stabilises.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eCamcorder shuts down mid-recording even with a charged pack\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eMid-recording shutdown on these camcorders is almost always a voltage sag issue, not a capacity issue. The CVL-series tape transport motor draws a current spike each time the tape mechanism engages — on a cell with elevated internal resistance, that spike pulls voltage below the body's cutoff threshold momentarily, triggering shutdown. Check that the battery contacts inside the bay are clean and making firm contact; oxidised contacts increase resistance and worsen the sag. If contacts are clean and shutdown continues, measure resting pack voltage with a multimeter — a healthy, fully charged 6V Ni-MH should read between 7.0V and 7.5V at rest.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43333899419738,"sku":"BWCS-NP66-1","price":50.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43333899452506,"sku":"BWCS-NP66-2","price":58.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43333899485274,"sku":"BWCS-NP66-3","price":64.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-NP66_1.webp?v=1778213590","url":"https:\/\/batteryweb.com\/products\/magnavox-cvl-345-replacement-battery-6v-4200mah-ni-mh","provider":"BatteryWeb","version":"1.0","type":"link"}
