Very pleased with the performance (so far) of the generic camera batteries, including dual USB charger, for my Canon EOS 60Da. The batteries were two thirds charged on arrival and the USB charger brought them up to full charge in half an hour or so. The battery with charger price was substantially lower than the OEM-branded versions. They arrived by post within 3-4 business days, with tracking. Time will tell if the batteries have the life of the OEM brand, but so far they are performing flawlessly. Thank you PowerAussie.
