Auto Repair Safety Notes

 

  • Charge the battery fully then test it with a battery tester. For more help follow this guide. Check the battery date sticker on the top or side of battery. Most car batteries last between three to five years.
  • During charging and jump-starting, explosive gases can escape from the battery. There is a risk of an explosion. Particularly avoid fire, open flames, creating sparks, and smoking. Ensure there is sufficient ventilation while charging and jump-starting. Do not lean over a battery.
  • Make sure that the positive terminal of a connected battery does not come into contact with vehicle parts. Never place metal objects or tools on a battery. It is important that you observe the described order of the battery terminals when connecting and disconnecting a battery. 
  • When jump-starting, make sure that the battery poles with identical polarity are connected. It is particularly important to observe the described order when connecting and disconnecting the jumper cables. Never connect or disconnect the battery terminals while the engine is running
  • Make sure the jumper cables are not damaged or wires are exposed.
