In Lead battery when the level of Electrolyte goes down it means that the acid concentration is going up which is not good for the Lead Cells.
This happens because of the evaporation of water in the acid, and because the water (H2O) is splitted into its components Hydrogen (H2) and Oxygen (O2) if the battery is overcharged, notice the bubbling from a battery if it is left on a (simple) charger too long.
Moreover the area which is active for production electricity is also reduced. So it is better to check and take corrective action to get better life and service.
Overcharging. Check your electrical system to see if the alternator is overcharging the battery. It can also be the battery is defective and needs replacing.
never
If the battery has caps and is not sealed check the level of the electrolyte. If it is low add only distilled water.
If the battery has removable caps: Remove the caps and add distilled water as needed to cover the plates with 1/4" of electrolyte. Or fill to the bottom of the "split" ring is battery is so equipped.
if its a maintenance free battery clean the terminals make sure its strapped down If not maintenance free, check the electrolyte level and top off with distilled water.
Lead acid batteries use a weak solution of sulfuric acid in water as an electrolyte. Some of the water evaporates if it is not a sealed battery, causing the electrolyte to become more acidic than normal. Adding water to the correct water level makes up for the evaporation and restores the battery acid solution to its proper strength.
Before you buy a new one, check the electrolyte level, discharge it completely through a 12 volt lamp and then try charging it properly. If it will not hold a charge there is no alternative than to replace it.
Same applies to all cars. A battery charger will be the best way, it slow charges the battery over along period of time, say 24 hours. Batteries only last about 4-5 years, so always check manufactures label on battery and charger, and charge in temperatures over 40 degrees F.. Charging should be done with cables off so not to damage computer. Charging a dead battery is passing current from positive to negative, instead of the reverse when it's slowly discharging. This changes the electrolyte level to its original state of charge. Again, the slow charging method as described above is the best. And don't forget to check electrolyte level on non maintenance free batteries.
No, some have top terminal, and some have side terminals. Batteries come in different CCA ratings (Cold Cranking Amps), basically it tells you the power-out of the battery and correlates with size of the battery. These days, all batteries are of the sealed type which means you don't have to add or check electrolyte level.

You simply look at the top of the iPod screen, and there should be a battery icon there.
