Cylindrical lithium-ion batteries the most commonly used power source in electrical and electronic devices. Generally, these batteries are quite safe but several lithium-ion battery-related incidents have been reported in the past. As a result, certain safety testing standards have been put in place to ensure that the battery that reaches the consumers does not pose any safety threats for them.

Lithium-Ion Battery Safety Testing Standards

Despite the fact that cylindrical lithium ion battery offers superior performance as compared to other batteries, they’re also associated with some safety concerns. Let’s have a quick go through of the top safety testing standards that ensure that the safety of the end-user is not at risk.

UN/DOT 38.3

Lithium-ion batteries are classified as Class 9 Hazardous Good and you can’t ship a lithium-ion battery via any route unless it has passed the UN/DOT 38.3 testing standard. This standard is a combination of mechanical, electrical, and environmental stresses that a battery is exposed to before it can be shipped. A lithium-ion battery that complies with this standard is deemed safe under the stresses that are a part of this standard. Some of the stresses include thermal testing, altitude simulation, external short circuit, overcharge, and forced discharge.

IEC 62133

The IEC 62133 is an international standard to see if the lithium-ion battery is safe for transportation. It is an integral part of the lithium-ion safety testing. It includes the following tests:

  • Molded Case Stress
  • Free Fall
  • External Short Circuit
  • Overcharging

This safety testing standard is fairly easy to pass as compared to the UN/DOT 38.3.

UL 2054

Compliance with the UL 2054 testing standard is mandatory. It involves about twice the number of tests as compared to both the UN/DOT 38.3 and IEC 62133. The tests included in this standard are:

  • Electrical tests (7)
  • Battery enclosure tests (4)
  • Mechanical tests (4)
  • Fire exposure test (1)
  • Environmental tests (2)

What Do You Need To Know To Avoid Damaging The Battery?

Although lithium-ion batteries, both small and large, are run through extensive safety testing, you need to make sure that you don’t expose the battery to any potential hazards. Below is a list of things you need to know to avoid damaging your lithium-ion battery.

  • Inserting them wrong can damage the lithium-ion battery. Make sure you insert the battery the right way.
  • Overheating the batteries can possibly damage them. Therefore, avoid overcharging them.
  • Charging lithium-ion batteries over flammable materials raises a safety concern. Avoid charging your lithium-ion battery over your couch, bed, or paper.
  • Keeping these batteries where there are exposed to heat directly, such as under direct sunlight and radiation, can cause extensive damage.
  • Exposing your lithium-ion battery to water or wet environments can cause them. You need to keep them away from water to avoid any damage.
  • Leaving batteries in open can also cause damage. Store them away in a safe, cool, and dry place.

Anything can go wrong anytime with electrical devices. The best way to ensure safety is to purchase cylindrical lithium-ion batteries from trusted sources only such as LARGE and follow all the right safety measures.
