whats a good heavy duty battery?

had the 510 rebuilt with a high compression piston and ported and flowed its running that much compression ot sorted me old battery out it was on the way out .so im off to get a new one but which one after some tips on what sort of battery i should get? . cheers

There is a good list of batteries in the aftermarket general list thread under common technical stuff.

i probably should rephrase the question is there an advantage with these gel batteries over a good heavyduty old style battery

I had a Super-B battery in my hands not too long ago. Incredibly light.

They are a bit expensive though.

Main advantage as I see it is you don't run the risk of blowing yourself up if you flip the battery upsided down! See the post regarding my TE310!

Interstate batteries are the best!
