How to choose emergency light batteries?

With the development of society and the improvement of people's safety awareness, emergency lights have become an indispensable equipment in homes, workplaces, and public facilities. Emergency lights are used to provide illumination in the event of a malfunction in the conventional power supply, as well as to illuminate firefighting equipment and exit routes, allowing personnel inside the building to safely leave according to instructions. However, to ensure the safe and stable operation of emergency lights, batteries are a key component. As a professional manufacturer of emergency light batteries, Zhongke Lithium Battery will provide you with an explanation on the selection of emergency light batteries.

When choosing emergency light batteries, the entire lifecycle cost of the battery, including post maintenance costs, should be comprehensively considered. A comprehensive evaluation can be conducted through the following aspects: battery life, cycle life, safety performance, charging performance, environmental friendliness, etc.

Battery life

When choosing emergency light batteries, the primary consideration is the battery life. The battery life refers to the duration during which the battery can continuously power the emergency light. Many countries have strict requirements for the duration of power supply for emergency lights in different usage locations, so the battery life of emergency lights must meet the duration required by local laws and regulations.

Cycle life

Cycle life refers to the number of charge and discharge cycles that 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 standby mode frequently and will only start when there is a power outage. Therefore, batteries with high cycle life can increase the service life of emergency lights and reduce the cost of battery replacement. Among the emergency light batteries currently available on the market, lithium iron phosphate batteries have the longest cycle life. Among them, Zhongke's lithium iron phosphate batteries can achieve over 2000 cycles under 100% DoD conditions.

safety performance

Safety is also an important factor in battery selection that cannot be ignored. Emergency light batteries need to have functions such as overcharging, overdischarging, overcurrent, and short-circuit protection to ensure that safety accidents do not occur during use. At the same time, 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 seen that power outages are sudden, so the emergency light battery should have fast charging performance and be able to maintain the battery's full charge at all times, ensuring the maximum endurance of the emergency light in the face of emergencies.

Environmental Friendliness

Environmental friendliness is an increasingly important consideration in modern battery selection. Especially European countries have a strong environmental awareness, which also affects their product choices. At present, lithium iron phosphate batteries on the market are more environmentally friendly compared to other types of batteries, with no heavy metal pollutants and no pollution to the environment. So, choosing environmentally friendly batteries is not only beneficial for protecting the ecological environment, but also in line with the concept of green development.

In summary, the selection of an appropriate emergency light battery should be based on factors such as battery life, cycle life, safety performance, charging performance, and environmental friendliness, taking into account the entire lifecycle cost of the battery, and choosing the most cost-effective emergency light battery.

Here, we recommend Zhongke's lithium iron phosphate emergency light battery (3.2V 3.3Ah 1S1P emergency light battery and 6.4V 3.3Ah 2S1P emergency light battery). It uses 26650 lithium iron phosphate battery cells, which have the characteristics of high capacity density, low self discharge rate, long cycle life, high stability, compliance with RoHS requirements, and maintenance free. At the same time, it adopts a long float charging design to keep the battery fully charged, ensuring reliable lighting and safety protection in emergency situations.
