The table shows the most widely used conventional names for the intervals between the notes of a chromatic scale. A perfect unison (also known as perfect prime)[5] is an interval formed by two identical notes. Its size is zero cents. A semitone is any interval between two adjacent notes in a chromatic scale, a whole tone is an interval spanning two semitones (for example, a major second), and a tritone is an interval spanning three tones, or six semitones (for example, an augmented fourth).[a] Rarely, the term ditone is also used to indicate an interval spanning two whole tones (for example, a major third), or more strictly as a synonym of major third.
Intervals with different names may span the same number of semitones, and may even have the same width. For instance, the interval from D to F♯ is a major third, while that from D to G♭ is a diminished fourth. However, they both span 4 semitones. If the instrument is tuned so that the 12 notes of the chromatic scale are equally spaced (as in equal temperament), these intervals also have the same width. Namely, all semitones have a width of 100 cents, and all intervals spanning 4 semitones are 400 cents wide.
The names listed here cannot be determined by counting semitones alone. The rules to determine them are explained below. Other names, determined with different naming conventions, are listed in a separate section. Intervals smaller than one semitone (commas or microtones) and larger than one octave (compound intervals) are introduced below.

Éric Alfred Leslie Satie (French: [eʁik sati];[1] 17 May 1866 – 1 July 1925), who signed his name Erik Satie after 1884, was a French composer and pianist. Satie was an influential artist in the late 19th- and early 20th-century Parisian avant-garde. His work was a precursor to later artistic movements such as minimalism, repetitive music, and the Theatre of the Absurd.[2]
An eccentric, Satie was introduced as a “gymnopedist” in 1887, shortly before writing his most famous compositions, the Gymnopédies. Later, he also referred to himself as a “phonometrician” (meaning “someone who measures sounds”), preferring this designation to that of “musician”,[3] after having been called “a clumsy but subtle technician” in a book on contemporary French composers published in 1911.[4]
In addition to his body of music, Satie was “a thinker with a gift of eloquence”[5] who left a remarkable set of writings, having contributed work for a range of publications, from the dadaist 391[6] to the American culture chronicle Vanity Fair.[7] Although in later life he prided himself on publishing his work under his own name, in the late 19th century he appears to have used pseudonyms such as Virginie Lebeau[8] and François de Paule[9] in some of his published writings.

In music, hemiola (also hemiolia) is the ratio3:2. The equivalent Latin term is sesquialtera. In pitch, hemiola refers to the interval of a perfect fifth. In rhythm, hemiola refers to three beats of equal value in the time normally occupied by two beats

How should I start with this?
First you need to set the desired voltage and current limit. To charge a 12-volt lead acid battery, which has 6 cells in series, you need to set a voltage limit of 2.15-2.4V per each cell. So if it has got six of these in series you need to set the charging voltage limit to 12.9-14.4V.
The recommended charging current is between 10 and 30 percent of the rated capacity. So a 9Ah battery should be charged at about 2.5A, or lower. Once the battery is fully charged the current drops to a few percent of the rated Ah, which indicates the battery is charged.
how much do I loose if I try to charge it from 12v?
Anything above 2.15V/cell will charge a lead acid battery. This means below 2.15V/cell no charging will occur.
