What is UL 60335-2-318?

UL 60335-2-318 is a widely recognized standard for the safety of automatic battery chargers. This standard is developed by Underwriters Laboratories (UL), a global safety certification organization. It provides guidelines and requirements for ensuring the safe operation of battery chargers in various applications.

Importance of UL 60335-2-318

The UL 60335-2-318 standard is crucial because it addresses potential risks associated with battery chargers, such as electric shock, fire hazards, and overheating. By complying with this standard, manufacturers can demonstrate that their products meet stringent safety requirements and ensure the protection of users and their surroundings.

Battery chargers are used in various industries and everyday life, ranging from smartphones and laptops to electric vehicles and industrial equipment. Safety risks associated with faulty chargers can have serious consequences, including property damage, injuries, and even fatalities. Therefore, adherence to UL 60335-2-318 is essential to minimize these risks.

Key Requirements of UL 60335-2-318

UL 60335-2-318 defines specific tests and criteria that battery chargers must meet in order to be considered safe. These requirements cover aspects such as electrical insulation, mechanical strength, protection against electric shock, temperature limits, and fault conditions.

For example, the standard specifies minimum clearances and creepage distances between live parts and accessible parts to prevent electric shock. It also sets limits on surface temperatures to avoid burn hazards. Additionally, battery chargers must incorporate suitable protective measures to handle abnormal situations, such as short circuits or excessive temperature rise.

Furthermore, UL 60335-2-318 mandates strict evaluations and testing procedures for battery chargers, including insulation resistance tests, dielectric voltage withstand tests, and temperature rise measurements. These tests aim to verify compliance with the standard and ensure the safe operation of the chargers under normal and abnormal conditions.


UL 60335-2-318 plays a vital role in ensuring the safety of automatic battery chargers. By complying with this standard, manufacturers can provide users with products that have undergone rigorous testing and evaluation, minimizing the risks of electric shock, fire, and other potential hazards. As consumers, it is important to choose battery chargers that meet UL 60335-2-318 requirements to protect ourselves and our surroundings from potential risks associated with faulty chargers.
