Duracell Laptop Battery Tips
What is the marine cranking rating (MCA)?
The marine cranking ampere (MCA) rating refers to the number of amperes a battery can support for 30 seconds at a temperature of 32°F until the battery voltage drops to 1.20 volts per cell, or 7.20 volts for a 12V battery. Thus, a 12V battery that carries a MCA rating of 600 CCA tells us that the battery will provide 600 amperes for 30 seconds at 32°F before the voltage falls to 7.20V. Note that the MCA is sometimes referred to as the cranking amperes or CA.
What is HCA rating?
The full form of HCA is hot cranking amperes. It is the same thing as the MCA or the CA or the CCA, except that the temperature at which the test is conducted is 80°F.
What is a VOLT?
A Volt is the unit of measure for electrical potential.
Is there a maximum temperature for charging lead acid batteries?
When charging lead acid batteries, the temperature should not exceed 120°F. At this point the battery should be taken off charger and allowed to cool before resuming the charger process.
