Amps Iec

In car Batteries, are there any conversion charts between DIN, IEC,CCA, etc?hat would you like to ask?

With many batteries on the market, to me, the CCA or Cold Cranking Amps is understood best. I am trying to find out if there are any conversion tables that I could refer to to convert between the many standards used DIN, IEC, CCA, etc etc.

Example: I have a plate on a battery listed as
MF78- 630
12V 70AH
CCA (IEC) 410.
when I take the reading on the normal load tester it is giving me a reading of 700CCA and more.

Kindly advise if there are any charts or tables I can find and follow.

Thanks.

You can only load test a fully charged battery to 1/2 the CCA for 15 seconds.
In this case,this should be load tested to 205

First number is Battery number/style.Usually by this number it can be determined what vehicle it will fit by post style,height etc.
12v= 12 volt
70 AH= 70 Amp

CCA, CA, AH and RC what are these all about? Well these are the standards that most battery companies use to rate the output and capacity of a battery.

Cold cranking amps (CCA) is a measurement of the number of amps a battery can deliver at 0 ° F for 30 seconds and not drop below 7.2 volts. So a high CCA battery rating is good especially in cold weather.

CA is cranking amps measured at 32 degrees F. This rating is also called marine cranking amps (MCA). Hot cranking amps (HCA) is seldom used any longer but is measured at 80 ° F.

Reserve Capacity (RC) is a very important rating. This is the number of minutes a fully charged battery at 80 ° F will discharge 25 amps until the battery drops below 10.5 volts.

An amp hour (AH) is a rating usually found on deep cycle batteries. If a battery is rated at 100 amp hours it should deliver 5 amps for 20 hours, 20 amps for 5 hours, etc.
