electrical issue need help fast

[Mattsauces]

Recently i have been experiencing an electrical issue with my 96 4.0 explorer. Whenever i try and start it after it has been sitting for a while (couple hours-day) it takes a while to start. My battery voltage is low but since i have an optima red top i still am able to start the truck without a jumpstart. i used a volt meter to check the voltage, when off it was 12.33 and 14.29 when on. There is a current draw of 0.40 amps when it is off. Is this enough to drain the battery or is that just the cars computer? i have checked the alternator and it is fine. Might my optima battery be bad, i bought it less then a month ago and this issue started 2 weeks ago.
