What you need to know before building your shield.
IMPORTANT ! The 2 most important point to note is..... Does you car need to be re-tuned if you remove your battery?
Second, do you have the PIN code to unlock your radio should your radio unit relock itself ?
Please do not remove the battery terminals if you are unsure of any of the above.
Get measurement of your battery dimension (width x length x height ). Cut with a sharp blade and use a flat head screwdriver to mark the folding lines.
Allocate about 5cm extra space to make a "flap". Use double sided tape to secure the battery shiled. VoilĂ , now you have a battery shield.
Download your battery sizes and spec here. I find it useful, and don't forget to thank them.
