Cold crank amp to start z3
Does anyone know what CCA is required?

Depends on the temperature of the oil, and wether you dip the clutch. Probably about 400-600 amps.

Re: Cold crank amp to start z3
The higher the CCA,the better the kick when you turn the ignition key.Unfortunately,the higher the CCA,the higher the cost of the battery,generally.
Re: Cold crank amp to start z3
Nothing to add really. If its cold, the oil is more viscous, therefore harder to rotate the crank in. Dipping the clutch saves the starter from turning the gearbox over as well, so it's better.dallantan wrote:Pease advise further on this...OXO wrote:Depends on the temperature of the oil, and wether you dip the clutch.

Ahhhh, I see. I got it
SO.....if I had two batteries linked in series, that held a higher CCA overall, this would be fine?

Re: Cold crank amp to start z3
Linked in parallel,and no,two batteries doesn't increase the CCA.Two batteries,in theory,are capable of holding more charge in reserve.In practice,one can drain into the other,one might not charge properly,there is a risk of fire.Far too complicated for me but others will be along shortly to set you straight.dallantan wrote:Ahhhh, I see.

Re: Cold crank amp to start z3
Linked in series doubles the volts to 24 and that would do a lot of damage to the electronics.dallantan wrote:Ahhhh, I see. I got it

You can link in parallel, but only for a short time, like when jump starting. As geminmustang says, there is a risk of fire if one of the batteries linked in parallel has a faulty cell, and it drains all the power from the good battery.
Re: Cold crank amp to start z3
If the additional battery is being used a lot when the ignition is off you'll need a split charge relay which ensures the starter battery isn't drained by the additional battery. Google "leisure battery wiring" and you should find what you're looking for. What's this battery being used for, or is it a secret
