For example, let''s think about a 12 V battery that has a capacity of 100 Ampere-hours, or Ah. When the battery has lost about 25 Ah or more, the lead sulfate in the battery will have achieved critical density. At that density, the lead sulfate will precipitate out of the solutions and form lead sulfate crystals.
