Performance

The performance of a car battery is normally expressed as follows

  1. Cold cranking amperes, CCA. See the explanation in «Cold cranking amperes»(ref-406822-S03931359532011070100000)
  2. Reserve capacity, RC. See the explanation in «Reserve capacity, RC»(ref-406822-S03373674412011070100000)
  3. Capacity, C20 (in certain cases). See the explanation in «Capacity»(ref-406822-S00343372112011070100000) .

Recommended charge current

The cold cranking amperes according to the SAE and DIN norms and the corresponding capacity and recommended charge current are shown in the tables below.

Volvo battery labels

The illustrations show an example of how the battery labels may appear.

European label

  1. Cold cranking amperes, CCA, according to the SAE norm (520 A)
  2. Volvo part number (9472329)
  3. Reserve capacity, RC, according to the SAE norm (95 min)
  4. The nominal terminal voltage of the battery (12 V)*.

American labels

  1. The nominal terminal voltage of the battery (12 V)*
  2. Capacity (60 Ah)
  3. Cold cranking amperes, CCA (550 A)
  4. Reserve capacity, RC (100 min)
  5. Volvo part number (9459947).

* 12 V is the nominal terminal voltage. This means that the battery has a stand-by voltage of 12.72 V when fully charged. Note that a battery with a stand-by voltage of 12 V is only charged to approximately 35% of capacity (see the diagram in Acid density ).

Removing and installing batteries

Removal

  1. Always disconnect the battery negative lead first. This is to prevent spark build up when removing the battery.

Installation

  1. Connect the positive terminal first. Apply acid resistant grease (P/N 1 161 150-6) to the battery posts where the clamps were screwed into place.

Checking the battery

Ensure that the battery is fully charged and in good condition upon delivery. The battery must be checked every other month prior to delivery according to Fault-tracing and testing the battery .

If necessary, charge the battery according to Battery, charging

A maintenance scheme for batteries will be supplied with new cars from the factory. There is a decal on the inside of the windshield. This decal indicates when the battery was checked and approved at the factory. The decal also gives the months when the battery should be checked and the maintenance schedule filled in. Everyone who is responsible for the car during transport and storage, before it is sold to the customer, is responsible for filling in the maintenance schedule.

The battery must be checked before the end of the month listed. It must also be checked a final time a few days before delivery to the customer. The decal must be removed when the car is delivered. The maintenance schedule must be filed with the dealership for the duration of the car warranty. Check that the chassis number of the car is included on the maintenance schedule before removing it from the car for filing.

In the event of a manufacturing fault in the battery, the maintenance schedule must be sent with the complaint to Volvo Car Technical Service, Volvo Car Corporation.

Scheme 18

Scheme 18: Checking the battery

The maintenance schedule is as follows

The text is in English only.

The maintenance schedule is in the glove compartment when the car is delivered from the factory.

Fill in the maintenance schedule as follows

1. Fill in the date and signature

2. Fill in the voltage that was read off

3. Fill in if the battery is charged or replaced

Put the maintenance schedule back in the glove compartment.

Note. While in transit and similar, there may be occasions when the car is not accessible for battery checks during the check month. In such cases, the battery check must be carried out as soon as the car is accessible again.

After delivery, the maintenance schedule must be filed at the dealership for the duration of the car warranty.

Decals for S70/V70 and S40/V40 models

There are two types of decal for these car models. The decals are two colored. This means that the car battery must be checked every other month.

Reducing the stand-by current consumption

If a car is not going to be used regularly over a three week period, the fuses for the stand-by current consuming components must be removed. This is to reduce the stand-by current consumption.

Examples of continuous power consuming components

  1. Alarm
  2. Immobilizer
  3. Radio
  4. Clock.
