 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.
 Be sure area around battery is well ventilated.
 Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
 Study all battery manufacturer's specific precautions such as removing or not removing cell caps
while charging and recommended rates of charge
 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.
