A battle item is, as its name implies, an item given to a Pokémon during battle to enhance its stats. Like the stat-raising effects of moves like Howl and Agility, the stat rise is only temporary. These items cannot be used on a Pokémon if the specific stat is already raised by six levels.
There are two distinct types of battle items. The basic battle items introduced in Generation I each raise a particular stat by a single stage, with the exception of 
Guard Spec. which protects the party from stat reductions for five turns.
A second type of battle item was introduced in Generation V, and can only be used in multiplayer battles via the Wonder Launcher. Many of these items are more powerful versions of the basic battle items, raising a particular stat by 2, 3, or 6 levels, while others have an effect on the ally of the Pokémon during whose turn the items are used.
