I need to power a tiny wireless "nanny" cam in a place where no AC can be installed. The camera is only needed during a certain time frame each day. Currently using the best 9 Volt battery and get maybe 3 hours use before picture quality becomes unuseable. Is there any way to construct a large portable 9 v battery? I could use 6 hours. Thanks, please answer in group only.
