Harold,
Thanks for the info on the deep cycle batteries. I wasn't aware of the
difference. In Australia we have a brand of deep cycle battery called
'Optima'.
Check their site at:
http://www.optimabatteries.com.au/default.htm
They use thin lead plates wound into a tight spiral (see tehcnical section
on their site). Do you think they would be any good in a car?
I am interested as I was contemplating buying a deep cycle battery for my
TR4 with its generator based charging system as I thought they would be
better in the long term.
Regards,
Michael Gajic
