Battery is the opening track of Metallica's 1986 album Master of Puppets. Similar to the opening track from Ride the Lightning and ...And Justice for All (titled "Fight Fire With Fire" and "Blackened" respectively), "Battery" begins with a slow, clean guitar part which then explodes into full speed thrash. In this case, three acoustic guitars are layered harmonically before the drums and bass come in with distorted guitars playing a more melodic version of the acoustic part. This lasts until 1:06, when the guitars cut into a very fast minimalist thrash metal riff that is the basis for the rest of the song. In live concerts, the beginning is not played by the band but instead the actual recording is used (recently dropped 1/2 step in key, since the band tunes 1/2 step down).
The theme of the song revolves around the San Francisco thrash scene of the 1980s. The most prominent club played by Metallica was the Old Waldorf located at 444 Battery Street in downtown San Francsico. The tone of the song is one of familial ties and the positive release of energy through the common interest of metal. The lyric "Cannot kill the family, Battery is found in me" is a statement that while society at large doesn't understand the scene, those within it (i.e. "the family") will fiercely defend it as a show of solidarity against the glam scene that was popular in the Los Angeles area.
"Battery" used to be a constant part of the band's live set list, frequently as the opening or closing song. In some cases, it is also used as a song before the intermission. Since 2008 the song has usually been dropped from setlists. When played, the song may stop before the interlude, and James Hetfield asks the crowd "Are you alive?... How does it feel to be alive?" (this can be heard on the live album S&M) and followed by the solo played by Kirk Hammett. As seen in the documentary Some Kind of Monster, the auditioning of future bassist Robert Trujillo started, on his request, with "Battery". In the live version of the song played on the Live Shit: Binge & Purge album, intros to the songs "No Remorse", "Ride the Lightning", and "So What?" are played in the song. When performed with the San Francisco Symphony in 1999, the intro up to the thrash riff was instead played by string players in the symphony, utilizing pizzicato in the beginning (the original acoustic) then with bows for the rest.
Battery is tied with “Welcome Home (Sanitarium)” as being Metallica's 10th most-played song. The first performance was on March 27, 1986 in Wichita, Kansas. As of April 23, 2013, the song has been performed 865 times (the most recent being February 7, for the Night Before, pre Super Bowl show.)
