How do you replace battery on a 2003 Saab 9-3?

Answer 1

I am assuming this is not a 2003 Saab 93 convertible. I don't have any specific details about that particular model.

All other 2003 Saab 93s take a BCI group size 48[1] battery. This battery is available (in the USA) almost anywhere that sells car batteries, even if they don't list the Saab 93 in their application guide. A BCI group 47 battery, which is smaller, can also be used if a group 48 battery is not available.

To replace the battery:

1. remove the battery cover (two plastic screw clips)

2. make sure the key is out of the ignition switch,

3. disconnect the negative terminal with a wrench

4. disconnect the positive terminal with a wrench

5. use a socket and an extension to remove the battery hold-down on the edge of the battery

6. remove the battery from the tray

To install the battery:

1. put the battery in the tray

2. use a socket and an extension to tighten the hold-down on the edge of the battery (if you use a group 47 battery you will need to install the hold-down bolt in a different hole than it was in with the original group 48 size battery).

3. connect the positive terminal with a wrench. (It may be necessary to trim the edge of the battery tray with a file due to the fact that many group 48/47 batteries are a little shorter than the original battery. If the terminal hits the edge of the battery tray this is why)

4. connect the negative terminal with a wrench.

5. replace the battery cover.

[1]In the USA car battery sizes are specified as group sizes. In Europe DIN sizes are used. I have no idea what the equivalent DIN sizes for the Saab battery are, but in Europe I suspect there will be no problem finding on that fits.
