I Bought a brand new gold edition battery for my car and I have to keep re charging my battery because it keeps draining and I dont know why. Could you give me any reasons why it is doing so?

Get a test light and disconnect the negative battery cable now put the light between the cable and battery negative post is the light On? If so start removing fuses one at a time -the fuse that turns off the light is the trouble circuit. Then break out the electrical wiring diagram.

In the event you removed all the fuses and the light is still On disconnect the alternator batt. Feed and the connector-if this one turns off the light-the alternator has bad diodes.

Or you can use an ammeter which is the preffered method to check for an excessive parastic drain
