Working with Batteries
•
Batteries can store large amounts of energy and improper handling can be dangerous
•
Keep children away from batteries and acid.
•
Avoid getting electrolyte on your skin or clothes. It is acidic and can cause burns. If battery acid
contacts skin or clothing, wash immediately with water. Baking soda neutralizes lead acid battery
electrolyte. If electrolyte gets into your eyes, immediately flood your eyes with running cold water
for at least 20 minutes and get medical attention immediately. Eye protection is therefore
recommended.
•
Always keep metal objects or other materials that can short circuit the terminals of the battery
securely away.
•
Power-off the device before making or breaking the connections to the battery.
•
Observe technical instructions of the seller or the manufacturer of your battery
•
Check if all connections are tight and clean. Loose or dirty connections could result in overheating,
electrical sparks and fire. Use terminal grease where required.
•
Never smoke or allow a spark or flame in vicinity of the battery.
•
Never try to charge a damaged or frozen battery.
•
Read your car´s owner's manual. Some vehicle manufacturers may have special requirements before
disconnecting the vehicle´s battery (e.g. fuses that have to be removed or certain security demands).
Electrical Cables
•
If cables have to be fed through metal holes or other walls with sharp edges, use ducts or cable
bushings to prevent damage.
•
Do not lay cables which are loose or bent next to electrically conductive material (metal).
•
Do not pull on the cables.
