  3. roubles and trouble shootings

  Troubles	Causes	Trouble shootings
  The capacity of the battery decreases	1.The electrolyte has been used for a long time and the carbonate content in it is too high.	Replace the electrolyte
  	2.The electrolyte is un-properly used.	Replace the electrolyte
  	3.The electrolyte isn't enough,and the level of the electrolyte is below the top of the plates.	See Table 5
  	4.Harmful impurities contained in the electrolyte is too high.	Replace the electrolyte
  	5.The charge/discharge method is not correct.	See the 5.2 and 6
  	6.Short-circuit or slight-short circuit in the cell	Replace the short-circuit cell.
  	7.Short-circuit or slight-short circuit occurs out of the cell.	Keep the cells in a dry temperature
  	8.The instruments used is not correct.	Check and rectify the ampere meter and voltmeter.
  Voltage is uncorrect	1.The inner circuit of the cell is short or cut,the electrolyte has been run out.	Clean the cell, or change the electrolyte
  	2.The out circuit of the battery is short or cut.	Keep the cell dry,and check
  	3.Contact fault	Check and repair
  Bubbles appear in the inside of the cell	The electrolyte contains organic impurites	Replace the electrolyte
  The cell container swells	1.The positive plate swells.	If necessary,change the cell.
  	2.The vent is blocked up.	Clean with hot water or replace it.
