Looks high quality though. ### ⭐⭐⭐⭐⭐ They should work fine. Were fully charged when I got them *by J***K on November 16, 2015* Haven't used yet. Will do on Nov. 22. They should work fine. Were fully charged when I got them. I appreciate that. ### ⭐⭐⭐⭐⭐ Charge lasts twice as long as regular size battery's *by L***O on April 1, 2022* I use these to power both a Panasonic PV-GS80 videocamera and a PVGS85. A charge lasts about 2 hours for recording or playback, about twice as long as the original batteries' do. One problem: These batteries won't recharge in the original chargers for these videocameras (though they seem to fit), but Kastar sells relatively inexpensive rechargers that do recharge them. Also, this battery is noticeably heavier than the original battery, which can be a problem when hand-holding the camera for a long time when recording--no problem if you can rest the camera on a fencepost or a tripod--but the extra shooting time more than makes up for that inconvenience. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.it/products/15279324-kastar-battery-2x-replacement-for-panasonic-cga-du21-and-nv](https://www.desertcart.it/products/15279324-kastar-battery-2x-replacement-for-panasonic-cga-du21-and-nv) --- *Product available on Desertcart Italy* *Store origin: IT* *Last updated: 2026-05-11*
