How should the battery for an emergency light be selected?

With the development of society and the improvement of people's safety awareness, emergency lights have become one of the indispensable devices in homes, offices and public facilities. Emergency lights provide lighting when the regular power supply fails and highlight fire-fighting equipment and exit routes, allowing people in buildings to leave safely according to the instructions. However, to ensure the safe and stable operation of emergency lights, the battery, a key component, is indispensable. As a professional manufacturer of emergency light batteries, JUGO Lithium Battery will provide you with a guide on the selection of emergency light batteries.

When choosing batteries for emergency lights, the entire life cycle cost of the battery should be comprehensively considered, including the later maintenance cost. This can be done by taking into account the following aspects: battery endurance, cycle life, safety performance, charging performance, and environmental friendliness, etc.

Battery life

When choosing a battery for an emergency light, the first consideration is the battery's life. Battery life refers to the duration for which the battery can continuously power the emergency light. Many countries have strict requirements for the power supply duration of emergency lights in different usage scenarios, so the battery life of emergency lights must meet the required duration stipulated by local laws and regulations.

Cycle life

Cycle life refers to the number of charge and discharge cycles a battery can undergo. The higher the number of charge and discharge cycles, the longer the battery's lifespan. For emergency lights, the battery needs to be in a standby state frequently and only starts when there is a power outage. Therefore, a battery with a high cycle life can increase the service life of the emergency light and reduce the cost of battery replacement. Among the batteries currently available for emergency lights, lithium iron phosphate batteries have the longest cycle life. Among them, the lithium iron phosphate batteries from Juge have a cycle life of over 2,000 times under 100% DoD conditions.

Safety performance

Safety is also an indispensable factor in battery selection. Emergency light batteries need to have functions such as overcharge, over-discharge, overcurrent, and short-circuit protection to ensure that no safety accidents occur during use. At the same time, the battery materials should also have high thermal stability to effectively reduce the risk of fire and explosion.

Charging performance

From the usage environment of emergency lights, it can be known that power outages are sudden. Therefore, the battery of an emergency light should have a fast charging performance and be able to maintain its full charge at all times, so as to ensure the longest possible operating time of the emergency light in the face of unexpected events.

Environmental friendliness

Environmental friendliness is an increasingly important consideration in the selection of modern batteries. Especially in European countries, there is a strong awareness of environmental protection, which also influences their choice of products. Currently, lithium iron phosphate batteries on the market are more environmentally friendly than other types of batteries, without heavy metal pollutants and no pollution to the environment. Therefore, choosing environmentally friendly batteries not only helps protect the ecological environment but also conforms to the concept of green development.

In conclusion, when choosing the appropriate battery for emergency lights, factors such as battery life, cycle life, safety performance, charging performance, and environmental friendliness should be taken into account. The overall cost of the battery throughout its entire usage cycle should be comprehensively considered to select the emergency light battery with the best cost performance.

Here, we would like to recommend our huge lithium iron phosphate emergency light batteries (3.2V 3.3Ah 1S1P emergency light battery and 6.4V 3.3Ah 2S1P emergency light battery). These batteries are made of 26650 lithium iron phosphate cells, which feature high capacity density, low self-discharge rate, long cycle life, high stability, compliance with RoHS requirements, and maintenance-free. Additionally, they are designed with a long float charge, ensuring the battery remains fully charged at all times, thus providing reliable lighting and safety assurance in emergencies.
