Description: Yes you read that correctly - 10Farad capacitor. This small cap can be charged up and then slowly dissipated running an entire system for hours. Combine two in series for 5F/5V. Do not over voltage or reverse polarize these capacitors.
Dimensions: 13mm x 33.5mm

Used 4 of these to replace a backup battery in an old clock radio. In the course of changing it from a battery to a capacitor i found that the original Chinese workers forgot to add a diode. So that is why my 9v batteries were dying so quickly. The 7v AC was draining the 9v DC. In the end i left the caps anyway. Now i never have to replace that stupid battery ever again. Of course for longevity a battery would be better.
