vii) Remove personal metal items such as rings, bracelets, necklaces, and watches when working with a
lead-acid battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or the
like to metal, causing a severe burn.
viii) NEVER charge a frozen battery.
ix) If necessary to remove battery from vessel, always remove grounded terminal from battery first. Make
sure all accessories in the vessels are off, so as not to cause an arc.
x) Be sure area around battery is well ventilated.
xi) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
xii) Study all battery manufacturer’s specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
xiii) Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This
helps purge excessive gas from cells. Do not overfill. For a battery without cell caps, carefully follow
manufacturer’s recharging instructions.
