The charge level depends on the concentration of battery acid. As sulfate builds up on plates, it reduces battery performance. The cell plates become sulfated if the battery is low or the battery is left in a discharged condition for several days.
If the battery is low, it needs to be recharged to restore full power and to prevent possible damage to the battery. Difficult starting the engine because of slow cranking is also an indication of a flat battery. When the engine starter does not turn the engine on or the lights are dim, that means you have low battery. Deep cycle batteries have a thicker plate design and can survive a greater number of deeper discharge cycles.
(A hydrometer is an instrument used to measure the specific gravity of liquids i.e. A hydrometer tests the amount of sulfuric acid in the electrolyte. The solution, or electrolyte, triggers a chemical reaction that generates electrons. The lead acid battery is made up of plates, lead, and lead oxide with a 35% sulfuric acid (H2SO4) and 65% water solution. Basics of the Battery:īatteries store Direct Current (DC) electrical energy in the form of chemical energy. Just like your bank account, if you keep taking out and deposit nothing back, then you soon will have nothing. A battery will survive longer and be more effective and reliable if you take care of it. In order to obtain the best reliability and performance from industrial and automobile batteries, proper maintenance is essential.
