What Are Cold Cranking Amps? CCA Explained. | RELiON
Also, it''s worth noting that MCA amps are generally higher than CCA because batteries can produce more current at 32°F versus 0°F. Alternatively, hot cranking amps (HCA) measure the opposite of what CCA measures, as HCA is the amps that are needed to start an engine at 80°F. ... Engines are designed to only pull as much power …

What resistance/load do battery testers (AA or AAA) use in ohms?
I mean testing alkaline and NiMH 1.5 V and 1.2 V batteries, and by battery testers I mean the devices that normally show whether the battery is good, low, or needs replacing. Basically I am trying to determine what size resistor I should use to test the batteries mentioned earlier, and by size I mean ohms and watts.
How Many Cold Cranking Amps Do I Need?
Here are some tips on how to maintain and test your battery: Measuring CCA. Cold Cranking Amps (CCA) is the most important measure of a battery, and it is the typical rating used for selecting the appropriate battery for a vehicle. CCA is the amount of current a battery can deliver at 0-degrees Fahrenheit for 30 seconds without dropping …

If the current is too high it will blow the fuse on the multimeter, or blow up the battery. Wikipedia says the Energiser AA battery has an internal resistance of about 0.15R at room temperature. This gives around 10A current. However, the internal resistance of the multimeter may now have an effect, reducing the current.
