Classification of batteries by use according to the definition of the Royal Decree:

[The only batteries not included, for the moment, in the legislation, would be those that are incorporated into devices used in the field of national security.


Portable battery or accumulator: any battery, button battery, accumulator or battery that is sealed, can be carried in the hand and is not industrial or automotive, such as, for example, standard and button batteries, and accumulators used in mobile phones, video cameras, emergency lights and portable tools.

Inside the portable batteries we show you two different ways to classify them:
By their chemical composition (there are many; we mention only some of the best known)

Lithium batteries (in mobile phones for example)

Nickel batteries (used in drills and other large appliances)

Mercury or Lithium button batteries (used in watches and remote controls)

By their electrochemical characteristics or – what are primary and secondary or rechargeable batteries?

There are two types of batteries, primary and secondary:
→Primary (non-rechargeable) batteries are those in which the chemical elements cannot return to their original state after having transformed chemical energy into electrical energy (remote controls, clocks, flashlights, etc.).
→Secondary (rechargeable) are those in which the transformation of chemical energy into electrical energy is reversible, allowing them to be recharged and used several times. These batteries are also called accumulators (mobile phones, computers).


Industrial battery or accumulator: battery or accumulator designed exclusively for industrial or professional use or used in any type of electric vehicle.


Automotive battery or accumulator: battery or accumulator used for starting, or lighting vehicles.
