Type of Battery

• Lead batteries with liquid or gel electrolyte
• Lead/Antimony (PbSb)
• Lead/Calcium (PbCa), AGM, etc.

Capacity

• Quantity of electricity that the battery can supply
  in 20 hours (measured in amperes per hour).

Voltage

• Difference of potential between battery terminals
  (measured in volts).

Intensity

• Instantaneous current delivered for starting. This
  current is expressed (depending on the country and
  the manufacturer) using EN, IEC, SAE or DIN norms
  (expressed in amperes).
