It wasn't a deep cycle because we didn't buy it for this car but it's CCA rating was quite a bit higher than my car requires. I figured this would mean that it would also have a higher battery capacity. I'm not sure if it actually does because after charging it yesterday, during my commute today the car almost didn't want to start. I slightly delayed some people behind me so after that I kept the engine on for a little bit. When I got home, I started charging the battery but the charger was only drawing about 5 amps to start with when I set it to 10 amp charging. In half an hour it was reduced to about 1~2 amps which I think means that the battery was only discharged a little bit. Does this mean that my starter is to blame for the inability to start after EOC?
Thank you

Starters draw a lot of amps from a batt. It takes a lot of driving just to re charge the battery from 1 start let alone 50. They also get hot and can burn out if they're used too much in a small period of time. Also your alternator is going to draw a lot more to try and re charge the lost amps putting more drag on your accessory drive belt using more gas. A batt with significantly higher cca is also a lot heavier. Additional weight is also causing you to burn more gas. I use a 12 lb race battery. Are you really getting any benefit from shutting your engine off and constanly re starting it?
