Fullriver answer to enquiry re. using their HC20 in an NB
"The HC20 is a smaller type auxilary battery with a CCA rating of 230 amps. It is also a sealed battery.
If you are looking to replace an aux battery with a similar rating, then yes it's fine.
Howver, if you are replacing the main cranking battery, then I think the Maiata requires a battery of like 400 CCA's,..in which case it would not be okay."
Now we know that some members are using this model ok ,and I don't wish to start controversy, but I'm feeling I should look for a stronger battery with more in reserve for my NB as a replacement. The $139.50 delivered from probatteries.com.au was
tempting though......
