A 9 volt rechargable battery apparently can be charged with a AC charger 11.2VDC 40 mA. Can I connect a 12 volt basic car battery to provide myself with more/longer power supply? To explain what I try to do I try to convert an electronic trigger for a paintball gun to complete two circuits at the same time, But I think the regular small 9 volt battery will be drained too fast. The circuit #1 will be to trigger the cylinoid to shoot. The #2 circuit will switch a relay which will close the circuit for speaker wires. Thanks
