Battery Description. Buick GL7 (Export) 2000

For 1990-2009 cars

Caution: Batteries produce explosive gases, contain corrosive acid, and supply levels of electrical current high enough to cause burns. Therefore, to reduce the risk of personal injury when working near a battery:

• | Always shield your eyes and avoid leaning over the battery whenever possible.

• | Do not expose the battery to open flames or sparks.

• | Do not allow the battery electrolyte to contact the eyes or the skin. Flush immediately and thoroughly any contacted areas with water and get medical help.

• | Follow each step of the jump starting procedure in order.

• | Treat both the booster and the discharged batteries carefully when using the jumper cables.

The maintenance -- free battery is the standard original equipment battery. There are no vent plugs in the cover. The maintenance -- free battery is completely sealed except for two small vent holes in the side. These vent holes release the small amount of gas that is produced in the battery.

The battery has three functions as a major source of energy:

• | Engine cranking

• | Voltage stabilization

• | An alternate source of energy with a generator overload.

The battery specification label (example below) contains the following:

• | The test ratings

• | The original equipment catalog number

• | The recommended replacement model number

### Battery Ratings

A battery has two ratings:

• | Reserve capacity

• | Cold cranking amperage

When a battery is replaced, use a battery with similar ratings. Refer to the battery specification label on the original battery or refer to Battery Usage

### Reserve Capacity

Reserve capacity is the time (in minutes) necessary to discharge a completely charged battery to a terminal voltage of 10.5 volts under the following conditions:

• | A constant rate of 25 amperes.

• | A constant temperature of 27° C (80° F).

Refer to Battery Usage

### Cold Cranking Amperage

The cold cranking amperage is an indication of the ability of the battery to crank the engine at cold temperatures. The cold cranking amperage is the minimum amperage necessary to maintain 7.2 volts for 30 seconds at -18° C (0° F). Refer to Battery Usage
