Apple does not issue any warning about unplugging a charger before a battery is completely charged. Apple specifically uses the term "charge cycle" in referring to battery life and notes that, for example, charging your iPhone battery to only increase charge by 25 percent counts as 25 percent of a charge cycle, confirming a complete charge is not needed every time.
Acid stratification is worth a particular mention because when it occurs a battery can often have the same voltage as a fully charged battery giving the appearance that it is fully charged when it is anything but. This voltage issue can also lead some chargers to believe the unit requires no charge and so they will not operate.
If a sealed lead acid battery is not charged properly or is not allowed to fully charge, the lead sulfate can harden and form crystals on the plates. This process is called …
