Electrical Issue - Battery or Alternator?

[gtrboyy]

Read somewhere batteries are built buy just a few companies & just sticker or outside colour is main difference.

Other than that prefer larger CCA rating,long warranty,correct terminal sides & if they need lip on battery for tie down bracket it should be good.

Was recommended ctek years ago & still very happy with it although accidently bought charger probably meant for bikes...slower but still does a great job lol
