Hi mate
i think i saw a post where you said you had a JDM car and battery i would advice to do that same as me replace the battery for a UK spec one there are traders on here you can buy the terminals from cheap and the UK battery's have a lot more kick before i changed mine if i was doing short runs the battery would die or if i listened to radio while parked i could not restart with out a jump now i have changed to UK spec i have zero issues
regards
