Hi Guys,

Getting close to cranking my engine over now and I am looking into a suitable battery choice, I have narrowed it down to a Varley redtop 20 or Odyssey PC680 Battery. Any advise or experience or running either battery?

Thanks in advance

I ran a PC680 on a 220bhp XE with no problems

You'll probably already know though that these batteries don't like being discharged completely too many times as they struggle to recover
I had a battery kill switch on mine for when the car was sat in the garage for any length of time and used a trickle charger for the winter lay up)

Looks like they are made by the same manufacturer (DMS Technologies); comparison of specs:

An alternative, Tanya batteries

Virtually identical size, more oompf but bolts different size.

Check them in ebay as it was cheaper on there than buying direct.
