Tried starting vehicle in the morning, temp was about 70 degrees, car has the push to start button. Battery has been replaced with an aftermarket yellow top deep cycle battery about 2 months ago. When attempting to start, car acted as if the battery was very low it turned over, dash went black for about 3 seconds and car started very forcefully. Car had been parked under carport for about 16 hours. The day before car was in the same conditions and started right up no problems.
