Rechargeable battery brands


These brands are known for their reliability and deliver quality which means you can count on durable performance for various applications. Many of these brands can be supplied directly from stock. Our team is ready to assist in finding the perfect match for specific needs.


Total Cost of Ownership (TCO)

When investing in high-quality rechargeable batteries, it is essential to look beyond the initial purchase cost. Total Cost of Ownership (TCO) includes all costs over the lifetime of the batteries, including direct costs such as purchase, electricity use for charging, and any maintenance and replacement costs.


TCO also takes into account indirect effects on these costs, such as the impact of charging speed, life cycle and reliability.

By taking these factors into account, informed choices can be made that are economically beneficial in the long run. Durable batteries with a longer lifespan reduce the need for frequent replacement, providing both cost savings and environmental benefits.


Lithium-ion (Li-ion)

Lithium-ion batteries are versatile and efficient, ideal for everyday use in consumer electronics, as well as for more powerful applications such as electric vehicles. Their low self-discharge and high charge rate make them suitable for a wide range of products, while their longer life reduces the Total Cost of Ownership. Customers choose Li-ion when durability, weight and long-term efficiency are important.

The two main advantages of a Li-ion battery are:

  1. High energy density: With a capacity of up to 400 Wh/L, Li-ion batteries offer excellent energy storage capacity, making them ideal for applications where space and weight are limited, such as mobile devices and electric vehicles.
  2. Long life and maintenance-free: These batteries require no regular maintenance and have a long life, making them economically advantageous over the long term.

The two main disadvantages are:

  1. Sensitivity to temperature variations: Li-ion batteries perform poorly under extreme temperatures, which can limit their functionality in both very cold and hot environments.
  2. Strict storage and transportation requirements: Due to their chemical composition, Li-ion batteries require specific precautions during storage and transportation to minimise safety risks.


Lithium iron phosphate battery (LiFePO4)

Lithium iron phosphate (LiFePO4) batteries are an excellent choice for high-performance, long-term power needs in electronics. These batteries are often used in applications such as emergency power supplies and portable electrical devices, where safety, longevity and reliability are essential.


Customers choose LiFePO4 batteries when devices require stable operation and consistent power, such as medical equipment and high-end audio-visual systems.

The two main advantages of LiFePO4 batteries are:

  1. Maintenance-free and fully deep discharge possible: LiFePO4 batteries require no maintenance and can be fully discharged without damage, making them ideal for intensive use.
  2. Long life and high energy density: These batteries last considerably longer (longer than lead-acid batteries, for example) and offer high energy density, making them lighter and more efficient in energy storage.

The two main disadvantages are:

  1. High price: The purchase cost of LiFePO4 batteries is higher than that of many other battery types.
  2. Limited supply: The supply of LiFePO4 batteries is relatively limited, which can result in availability problems and less choice.


Nickel-cadmium (NiCad)

Nickel-cadmium (NiCad) batteries are distinguished by their excellent ability to withstand high discharges and their ability to perform in a wide range of temperatures. They are widely used in power tools and other devices that require robustness.


Their long life and reliability make them suitable for applications where durability is a requirement. Customers choose NiCad batteries because of their proven track record of reliability and consistency under demanding conditions.

The two main advantages of NiCad batteries are:

  1. Robust and high cycle time: NiCad batteries are extremely robust and can achieve a high cycle time with proper maintenance, making them reliable for long-term and intensive use.
  2. Good low-temperature performance and fast charging: These batteries perform well under low temperatures and can be charged ultra-fast with little stress on the battery, making them ideal for applications in cold environments and situations where fast charging is required.

The two main drawbacks are:

  1. Memory effect and low specific energy: NiCad batteries suffer from the memory effect, which means they need to be fully discharged periodically to maintain their capacity. Moreover, they have a relatively low specific energy compared to more modern battery systems.
  2. Environmental impact due to cadmium: Cadmium, used in NiCad batteries, is a toxic metal that can cause environmental problems, so these batteries should not be disposed of in landfills and require special recycling.

Nickel-metal hydride (NiMH)

Nickel metal hydride (NiMH) batteries are a more environmentally friendly alternative as they contain no heavy metals, unlike NiCad batteries. Because of their higher capacity and less memory effect, they are popular in various types of electronics, ranging from phones to digital cameras. Customers prefer NiMH for applications that require a higher energy density while creating less environmental impact.

The two main advantages of nickel metal hydride (NiMH) batteries are:

  1. Higher capacity: NiMH batteries have a 30-40% higher capacity compared to standard NiCad batteries, allowing them to store more energy and function longer between charges.
  2. More eco-friendly: These batteries contain only mild toxins, making them a more eco-friendly option than many other types. Moreover, they are profitable for recycling, contributing to a more sustainable battery solution.

The two main disadvantages are:

  1. Limited life when deeply discharged: The life of NiMH batteries can decrease significantly if they are repeatedly deeply discharged, with deteriorating performance after about 200 to 300 cycles.
  2. Complex charging algorithm and more maintenance required: NiMH batteries require a complex charging algorithm and regular full discharges to prevent crystalline formation and the associated memory effect, which requires extra effort and care during use.


Lithium polymer (LiPo)

Known for their light weight and flexible form factors, LiPo batteries offer superior energy density, making them essential for minimising weight in portable devices. These batteries can charge quickly and handle higher discharge rates, making them ideal for advanced applications such as drones, RC vehicles, and portable electronics such as smartphones and laptops.

The two main advantages of lithium polymer (LiPo) batteries are:

  1. Lightweight and high energy density: LiPo batteries are about 20% to 35% lighter than comparable NiMH batteries and contain more charge, offering a higher energy density. This makes them ideal for portable applications where weight and space are crucial.
  2. No memory effect and wide temperature range: LiPo batteries do not suffer from the memory effect, meaning they do not lose capacity due to partial charge cycles. Moreover, they function well under a wide range of temperatures, making them suitable for use in a variety of environments.

The two main drawbacks are:

  1. Prone to physical damage and overcharging: LiPo batteries are prone to physical damage and can be dangerous if not used correctly, especially when overcharged, which can lead to a fire hazard.
  2. Cost: Despite their advantages, LiPo batteries can be more expensive compared to other battery types such as NiCad and NiMH, which can be an obstruction to general use.
