AmpHour Calculator

This tool allows you to get the maximum current and time duration that a battery can put out.  You can specify the time in 24-hour format. So if you know the amp-hour capacity and the load you can then determine the time it will be running stable. It even intergrades with NL5 Circuit Simulator.
More calculators coming soon!

All programs are virus free. Some antivirus software might say its "suspicious" or a "Potentionaly Unwanted Program". Some of them rate them on what there code looks like no matter if theres a definition in the virus database. If any of them are detected any Antivirus I will zip the software with the password "justin" j is lowercase
