'Automobile Batteries'

• A battery is a type of electric battery that supplies electric energy to the starter motor and the ignition system of a vehicle’s engine
• Types: Car batteries have different uses and various other elements are alloyed with the lead such as calcium, cadmium or strontium to change density, hardness, or porosity of the plates and to make the plates easier to manufacture
• Fluid level: The majority of batteries today are maintenance free and don't require top up
• Charge and discharge: In normal automotive service, the vehicle's engine-driven alternator powers the vehicle's electrical systems and restores charge used from the battery during engine cranking
• Changing a battery: In the vast majority of automobiles, the grounding is provided by connecting the body of the car to the negative electrode of the battery, a system called negative ground
• Freshness: Because of sulfation, (see lead-acid battery), one should never buy a battery that is more than six-months old
• Exploding batteries: Maintenance free (MF) Batteries rely on valves fitted to each cell which can vent hydrogen if over-pressurisation occurs
• Ampere-hours: (A·h) is the product of the time that a battery can deliver a certain amount of current (in hours) times that current (in amps), for a particular discharge period
• Cranking amps: (CA), also sometimes referred to as marine cranking amps (MCA), is the amount of current a battery can provide at 32 °F (0 °C)
• Cold cranking amps: (CCA) is the amount of current a battery can provide at 0 °F (−18 °C)
• Hot cranking amps: (HCA) is the amount of current a battery can provide at 80 °F (26.7 °C)
• Reserve capacity minutes: (RCM), also referred to as reserve capacity (RC), is a battery's ability to sustain a minimum stated electrical load
• Peukert's Law: expresses the fact that the capacity available from a battery varies according to how rapidly it is discharged
• Hydrometer: measures the density, and therefore indirectly the amount of sulfuric acid in the electrolyte
