What is a battery?

Explore and understand the intricacies of the battery industry with BatteryGlossary.com, your ultimate resource for relevant terms and definitions. One or more cell s connected together electrically in series or parallel, or both, to provide the required operating voltage and current levels.

What is battery chemistry?

Battery chemistry is the combination of chemicals from which the battery cathode, anode, and electrolyte are constructed. Battery chemistry radically impacts battery characteristics and performance. Standard cathode chemistries include Nickel Manganese Cobalt (NMC), Lithium Iron Phosphate (LFP), and Lithium Cobalt Oxide (LCO).

What is a battery and how does it work?

A battery is a device that stores electrical energy through a chemical reaction and converts it back into electrical energy when needed. European legislation regulating the production, distribution, use, and disposal of batteries and accumulators.

What does C mean on a battery?

C is a term used to describe a battery’s discharge rate or charging current, often represented as a multiple of the battery’s capacity (e.g., 1C, 2C, 5C). Calendar life refers to the total lifespan of a battery, considering factors such as aging and environmental exposure.

What is battery capacity?

Capacity is a measure of the amount of electrical energy a battery can store, typically expressed in ampere-hours (Ah) or watt-hours (Wh). A correction factor that accounts for the reduced capacity of a battery when discharged at a higher C-rate than specified.

What is the nominal capacity of a battery?

Nominal Capacity: The nominal or named value of the rated capacity. In sealed lead acid (SLA) batteries, nominal capacity is usually measured at the 20 hour rate, which means the amount of current the battery can deliver for 20 hours before reaching the end point voltage of 1.75 volts per cell at 25°C.
