What is a lithium battery?
A lithium battery is one that uses lithium or a lithium alloy instead of lead to generate power. Lithium is the lightest metal and offers the greatest electrochemical strength and energy density per weight. This makes lithium batteries enormously energy efficient and suitable for applications where weight and space are limiting.

The advantages of lithium batteries
✓ High energy density
Lithium batteries can provide higher energy density than traditional rechargeable batteries such as nickel-cadmium (NiCd) or nickel-metal hydride (NiMH), and even higher than lithium-ion batteries. This makes these batteries ideal for applications such as mobile devices and laptops, where space and weight are minimal.
✓ Longevity
Lithium batteries have a long service life and can undergo hundreds to thousands of charge cycles before their capacity decreases noticeably.
✓ Charged longer
Lithium batteries have a low self-discharge that allows them to stay charged longer when not in use.
✓ Higher voltage
Lithium batteries provide a high average voltage, often around 3.5 volts, which is higher than the 1.2 to 1.5 volts of NiCd or NiMH batteries.
✓ lightweight
Lithium batteries provide not only high capacity with relative small space, it weighs significantly less than alternative battery technologies. Ideal for those applications where weight matters.
✓ Low maintenance
Lithium batteries require less maintenance than other battery technologies.

Application of Lithium batteries
Lithium batteries are widely used in devices that require long life and high energy density, such as pacemakers, watches, electronic devices and backup power systems. The range of applications continues to expand as the technology advances.
When should I choose for lithium batteries?
Lithium for motive applications
Applications mobile machines, robots and light electric vehicles often have limited installation space and strict weight restrictions.
The high energy density of lithium batteries makes it possible to store more energy in a smaller and lighter battery pack. In addition, lithium batteries support opportunity charging, allowing equipment to be charged during short breaks without negatively affecting battery life.
Lithium for energy storage
Energy storage systems require batteries that can be charged and discharged frequently while maintaining reliable performance over many years.
Lithium batteries offer a long cycle life, high round-trip efficiency and low maintenance requirements. These characteristics make them suitable for applications such as solar energy storage, peak shaving, self-consumption and commercial battery energy storage systems.
Lithium for the electification of machines
The electrification of construction equipment, utility vehicles and other heavy-duty machines places high demands on battery systems.
Battery packs often need to fit within existing machine designs while delivering sufficient power for intensive daily use. Lithium batteries are well suited for these applications thanks to their modular design, high power output and flexibility in custom battery configurations.
Lithium batteries for backup power
Lithium batteries are increasingly used in backup power applications due to their long service life, low maintenance requirements and compact design.

Lithium is the lightest metal and offers the greatest electrochemical strength and energy density per weight. This makes lithium batteries enormously energy efficient and suitable for applications where weight and space are limiting.
How long does a lithium battery last?
The exact life-time of a lithium battery varies. It depends not only on the type of battery (the exact chemistry), but also on the operating circumstances, how it’s used and stored. Lithium batteries have a long service life and can undergo hundreds to thousands of charge cycles before their capacity decreases noticeably.
What charger do I need for my lithium battery?
This depends on the type of lithium battery you have. There are 6V, 12V, 24V, 36V and 48V battery chargers with different charging currents, from 0.5A to 50A. In addition, there are various types of housing for battery chargers, such as plug chargers, table chargers and battery chargers with waterproof housings.
