Hi Guys,

I need to get a new battery and I had alway thought I'd just get a Yellow top, but from doing a little bit of reading I'm no longer sure.

The blue top which is advertised as a boat, RV battery has the same cranking power as the yellow top, it has more connecting terminals and it is generally cheaper to.

I can't see any benifit of get the yellow top battery?

I don't fancy the red top, as although you can get ones with more cranking power the longivity isn't there to run my ICE.

Blue or Yellow?

 

so, blue, yellow or red? What do people think?

 

You are correct, no difference other than the ones you have listed. The only thing is they don't do a reverse terminal in the Yellow or Blue, so you will have to work out extensions.

Think I'm going to get a blue one. Its going in the boot anyway so the reverse terminal isn' an issue.

I just can't figure out why the blue is so much cheaper if its the same as the yellow.

 

Anyone else have any views?

 

BTT

 

I have a red top on my 02 STI..

never had a problem starting it since.. usually the trackers/immobiliser/alarms drain the battery especially if you leave your alarm on for 1-2 weeks at a time!

no problems with a red top - turn the key and fires up straight away

expensive batteries but worth it in my opinion, the 6 cylinders look very different to your usual battery!
