Similar to CCA; Cranking amps is a measure of the number of amperes a lead acid battery at 32 degrees F can deliver for 30 seconds and maintain at least 1.2 volts per cell. (CA ratings are more commonly used in climates where temperatures rarely drop to 0F.)

Unlike CCA and MCA the pulse cranking ampere (PCA) rating does not have an "official" definition; however, we believe that for true engine start purposes, a 30 second discharge is unrealistic. With that in mind, the PCA is a very short duration (typically about 3 seconds) high rate discharge. Because the discharge is for such a short time, it is more like a pulse.(Return to Top) See similar questions...

This industry rating measures the cranking power a battery has available to start a car's engine at 0 degrees F. Battery Council International defines it as the number of amperes a lead acid battery at 0 degrees F can deliver for 30 seconds and maintain at least 1.2 volts per cell. See similar questions...

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.(Return to Top) See similar questions...

CCA is the maximum amperes that can be continuously removed from a battery for 30 seconds at 0?F before its voltage drops to unusable levels. A 550 CCA battery can supply 550 amperes for 30 seconds at 0?F. This rating is only useful in the selection of engine starting batteries. NOTE: Do not confuse Cold Cranking Amperage (CCA) with Marine Cranking Amperage (MCA) or Cranking Amperage (CA). MCA and CA is a higher battery rating measured at warmer temperatures.

amp-hour is one amp for one hour, or 10 amps for 1/10 of an hour and so forth. It is amps X hours. If you have something that pulls 20 amps, and you use it for 20 minutes, then the amp-hours used would be 20 (amps) X .333 (hours), or 6.67 AH. The accepted AH rating time period for batteries used in solar electric and backup power systems (and for nearly all deep cycle batteries) is the "20 hour rate". This means that it is discharged down to 10. See similar questions...

A CA is an acronym for Certification Authority. A CA is an independent party that verifies the identity of a SSL Certificate applicant. If the person or organization that is requesting the Certificate are proven to be who they claim to be, and their web address matches the proper public records, the certificate is issued and the applicant is able to send data using the SSL protocol, and therefore enabling Data Integrity, user authentication, and non-repudiation.

MCA is a measurement of the starting power of a battery at 32?F under a load (ampere draw) for 30 seconds with the end voltage maintained at 1.20 volts per cell. MCA is generally 20% higher than CCA (cold cranking amps). See similar questions...

CCA (cold cranking amps) is a measurement of the starting power of a battery at 0?F under a load (ampere draw) for 30 seconds with the end voltage maintained at 1.20 volts per cell. Several variations of CCA ratings may be applied to a battery including; MCA (marine cranking amps) or CA (Cranking amps), which are generally 20% higher than CCA (cold cranking amps) and reflect higher temperature testing.

PCA (Pulse Crank Amps) is a rating specifically geared towards starting applications only. PCA is a short duration (5 seconds), high rate discharge measurement generally used in the powersport industry. PCA is a rating used by Odyssey batteries. See similar questions...

Most General Surgeons in Modesto repair hernias. There are some urologists who also repair inguinal hernias. There are many different methods of hernia repair in Modesto. Ask your doctor in Modesto to see which type of hernia repair is best for you. Different types of hernia repairs include laparoscopic approach, open, different locations of hernia incisions, and different types of hernia mesh. You will undoubtedly have many more questions. Please ask them when you see your doctor. See similar questions...

With the lens you currently have, you can reduce CA by stopping down. You may also find that some focal lengths are more prone to CA than others. For zooms, CA is typically worst at one or both of the extreme ends of the range. Another way to avoid CA is to switch to a different lens. In general, extreme wide angle and extreme telephoto lenses are more prone to CA than "normal" lenses. Zooms are typically more prone to CA than fixed focal length lenses. See similar questions...

You can partially correct for chromatic aberration using software tools. If you are shooting in RAW, then there's a very nice interface to this through the Photoshop CS RAW converter, and now through CS2 even without the RAW converter. If you aren't using a recent version of Photoshop then it can be done using using Picture Window Pro, as described by Norman Koren. Another alternative is to use panorama tools. See tutorial 1, or tutorial 2. See similar questions...

A Certification Authority is a trusted third party that verifies the identity of an entity registering for a digital certificate. Once a Certification Authority authenticates the requesting entity's identity, it issues a digital certificate to the requesting entity binding his or her identity to a public key. (Digital certificates can be issued to organizations and devices in addition to people) See similar questions...
