No you can not use this power supply 12 V DC 500 ma instead 12VDC 1amp because this battery will not able to deliver sufficient power to that device which you want to power it from this battery and your device will not work fine or it will work with very poor performance.
The device may take more current from power supply....so cannot be used
Yes the power source has the ability to supply a maximum of 3000 mA. The device only draws 500 mA. So there is ample supply left from the source.
The current rating on a charger ("1000 mA", "500 mA"), usually means the currentthat the charger is capable of supplying if it needs to. It's NOT the current that'salways being pumped out.If your 7AH battery needs 500 mA at some time during the charging operation,then a 1000mA charger is capable of supplying it.
