How to Charge an 800 CCA Battery
Get ready to sit and wait when charging your 800 CCA battery (

Cold Cranking Amps (CCA) is a rating used to define a battery's ability to start an engine in cold temperatures. The higher the CCA rating, the greater the starting power of the battery. Six-cylinder gasoline engines, as well as 4- and 8-cylinder diesel engines, work optimally with an 800 CCA battery. When your voltmeter tells you your battery needs charging, be prepared to wait. The length of time it will take to charge an 800 CCA battery depends on its voltage, but can range anywhere from 4 to 16 hours.

Moderately Easy

Things you need

  • Charger with at least 50 amps
  • Electrical sockets
  • Voltmeter
  • Battery
  • Owner's manual and charger safety manual

  1. 1

    Plug the battery charger into an electrical socket. Make sure the cord can extend to where your car is parked so you won't have to remove the battery for charging.

  2. 2

    Familiarise yourself with the charger clamps. The positive (+) clamp is usually red and the negative (-) clamp is black.

  3. 3

    Attach the negative charger clamp to the negative (-) battery post. The battery post should be clearly marked on your battery or on your car manual.

  4. 4

    Attach the positive charger clamp to the positive (+) battery post. The battery post should be clearly marked on your battery or on your car manual.

  5. 5

    Move the knob to the "charge" selection.

  6. 6

    Flip the power switch on the battery charger to "on."

  7. 7

    Continue charging on until the charger's indicator lights shows the voltage level as adequate. Many chargers have an automatic sensor that will cut off power when the battery is fully charged.

  8. 8

    Turn the power switch to "off," unplug the cord from the wall and remove the clamps. Your 800 CCA battery should now be fully charged.

Tips and warnings

  • If you live in a warmer climate, it is not a good idea to buy a battery whose CCA exceeds your car's starting requirements. In cold climates, however, a higher CCA rating is better because more power is needed to get a sluggish engine going when temperatures drop.
  • Batteries contain sulphuric acid that can cause burns, as well as gases that are highly flammable and explosive. Be sure to read your owner's manual and the charger safety instructions before charging any car battery.
