I constantly need to replace my battery, i have the most powerful Delco battery and it last between 6 monts to 2 year, i dont have current drain, my alternator was in specs but always have the same problem, my oem battery last 5 years, i have a type d amplifier and use the car all days all years, any solution?

 

That's not that bad actually. I been using the Duralast Gold. Its been good.

 

This seems a bit too soon (and $$$). Maybe, a parasitic drain on the battery?

Six months to two years is a huge difference. If the OP said that 2 car batteries drained in 6 months than we could say there is a problem. However, the OP also said that he's running an amplifier in the car, this is most likely paired with a subwoofer. If so, perhaps the OP abuses the battery more than other s2000 owners by bumping music while the car is off. This could make batteries die faster.

 

Even two years, would get kinda $$$. Maybe he needs a bigger alternator.

 

Or something in the sound system isn't hooked up properly and causing a parasitic drain. For instance, if the amp was hooked up to the constant +12v instead of the switched +12v it could be drawing current while the car is off, greatly reducing battery life.

 

Mine last about 5 years,these are not large batteries. I have a trickle charager for it as I only do about 5000 or less a year now.
