Difference between a battery and a rechargeable battery

What is the difference between a battery and a rechargeable battery?

The word “accumulator” is derived from the Latin word meaning “to collect” or “to store.” A rechargeable battery stores energy, such as electricity, and can release it when needed.

In the past, before rechargeable batteries became common, the distinction was simple: batteries could not be recharged, while rechargeable batteries could. Nowadays, people often refer to “rechargeable batteries,” which are technically rechargeable cells in the shape of standard batteries.

In practice, however, the distinction is often based on the shape and application.

Distinguishing by shape

Most people distinguish between batteries and rechargeable batteries based on their form factor. Batteries are often available in standardized sizes such as button cells, AA, AAA, C, D, 4.5 V, and 9 V. Rechargeable batteries, on the other hand, are often specifically designed for a particular device or application, such as automotive systems or industrial equipment.

Non-rechargeable and rechargeable batteries

Since the main difference between battery types is whether they can be recharged after use, professionals generally distinguish between:

• Non-rechargeable batteries (primary batteries)
• Rechargeable batteries (secondary batteries)

Different types of batteries and batteries

As a battery specialist, we at Elfa know the differences between the different types of batteries. Of course, this is important to know in order to make the right decision. We have the following batteries and batteries in our range. A number of them are further explained on this page:

1. Non-rechargeable batteries

• Alkaline
• Lithium
• Zinc air-alkaline

2. Rechargeable batteries

• Lithium ion
• Lithium iron phosphate
• Lithium polymer
• Nickel metal hydride
• Nickel cadmium

3. Battery systems and accumulators

• Lead-acid battery
• Sodium-ion salt water
• Lithium iron phosphate

Rechargeable batteries: Li-ion and LiPo batteries

Li-ion batteries offer many advantages: they are lightweight, have a high energy density, and exhibit very low self-discharge. Li-ion and LiPo batteries are dominant battery technologies in mobile applications because they combine excellent energy density with relatively low weight.

Li-ion batteries are generally recognized by their cylindrical cell shape, while lithium polymer batteries are known for their flat, prismatic design.

This Panasonic Li-ion cell offers high energy capacity, minimal self-discharge, and a long lifespan. It is a powerful battery that operates within temperatures from -20 °C to +60 °C, making it suitable for industrial applications.

1. Lead acid batteries

In many cases, we advise customers to use lead-acid batteries. We supply these batteries for sectors such as defense, power plants, and industrial systems.

Our range includes VRLA (Valve Regulated Lead Acid) and SLA (Sealed Lead Acid) batteries. These batteries are known for their sealed and maintenance-free construction.

We distinguish between two methods of electrolyte stabilization:

• GEL
• AGM

This Fiamm AGM battery is designed for demanding backup power applications. It is ideal for UPS systems, emergency power supplies, IT centers, and security systems. The battery features low self-discharge and supports deep discharge during emergency situations.

This Mastervolt GEL traction battery is designed for professional applications, especially in environments where traditional power sources are unavailable. Typical applications include emergency power systems, forklifts, and alarm systems.

2. Sodium-ion saltwater batteries

A saltwater battery is an electrochemical energy storage system that uses a saltwater-based electrolyte. These batteries are particularly suitable for solar energy systems because they are optimized for daily deep discharge cycles.
