Working with Batteries
• Batteries can store large amounts of energy and improper handling can be dangerous. Never connect
to a battery with an unsuited voltage or other unsuitable or damaged batteries
• 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. A resulting spark or short-circuit may not only damage the device, but also cause an
explosion and potentially produce a current high enough to weld a ring or the like to metal. Remove
personal metal items such as rings, bracelets, necklaces, and watches when working on the device or
the battery.
• Power-off the device before making or breaking the connections to the battery.
• Depending on the type of battery, when a battery is being charged, you may notice bubbling in the
fluid caused by the release of gas. As the gas is flammable, avoid naked flames, glowing or
electrostatically charged material and sparks in the vicinity of the battery. Always provide adequate
ventilation when charging a battery.
• Observe technical instructions of the seller or the manufacturer of your battery. Observe your car´s
owner's manual.
• Only put the device in operation if the device and all cables are undamaged. Check if all connections
are tight and clean. Loose or dirty connections could result in overheating, electrical sparks and fire.
• If necessary, clean the battery´s terminals and 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. Never jumpstart a car with a frozen battery.
• Do not place the device directly on top of the battery or vice versa or on a surface constructed from
combustible material.
