about how many cold cranking amps are normal honda car batteries?
is it better to have more amps/hour say 22 as opposed to 13?
and why is it harder for a battery to work cold anyways?

 

nevermind say a battery is rated at 100AH, then itll supply 50 A for 2 hours, 2 A for 50 hours, etc.

you probably need above 300CCA

 

Most Honda Civics require 410 cca (cold cranking amps) A few 2003 require 435 cca. This is a rating at 0 F not to be mixed up with ca (cranking amps). ca is a 32 degree reading. Also Civics will take a group 51 or group 51R.

 

Batteries have an internal resistance. This resistance increases with cold temperatures. This resistance is in series with the starters' resistance. When current flows through a series circuit, voltage drops occur across these resistances. So the higher the resistance of the battery, the more voltage that will be dropped across it and not across the starter.

One common solution to this, on very cold days....turn your headlights on for a few minutes. Current flows and heat is created, thus decreasing the internal resistance of the battery.

thast what i said. read above
