How to boost battery effiency and extend longer life time??
Posted: Sun Nov 06, 2011 1:19 pm
Hello, recently I have a problem for my project that 9v battery drain the current faster than i thought(Battery death very fast).
My project connect from battery then go though LM7805 only link with MCU, RF module x2, Graphic LCD. May I know how to calculate my project required how much current or power to maintain working?? How much current will be discharge from a non-recharge battery actually??
I found (Battery DC Boost Converters Using MCP1640) at website but i dont know how to connect to MCU that might cause MCU damage.
Any power electronic expert here can help me??
