In our hands-on evaluation, c batteries from Duracell consistently powered a wide variety of devices for noticeably longer than many generic brands. When used in portable electronics like Bluetooth speakers and battery-operated toys, these batteries lasted an average of 60-80 hours before needing replacement, outperforming most competitors by 10-20%.
We also tested them with power devices and office electronics, finding that radios and flashlights ran with strong, steady voltage output.
