With the development of society and the improvement of people's safety awareness, emergency lights have become one of the indispensable devices in households, office places, and public facilities. Emergency lights are used to provide illumination when the regular power supply fails and to highlight firefighting equipment and exit routes, enabling people in the building to evacuate safely according to the instructions. However, to ensure the safe and stable operation of emergency lights, the battery, as a crucial component, is indispensable. JUDA Lithium Battery, as a professional manufacturer of emergency light batteries, will provide you with a guide on choosing emergency light batteries.


When selecting emergency light batteries, the overall life cycle cost of the battery should be considered comprehensively, including the later maintenance cost. This can be evaluated through the following aspects: battery runtime, cycle life, safety performance, charging performance, and environmental friendliness.


Runtime
When choosing emergency light batteries, the primary consideration is the battery's runtime. Runtime refers to the time during which the battery can continuously power the emergency light. Many countries have strict requirements regarding the power supply duration of emergency lights in different usage scenarios. Therefore, the runtime of emergency light batteries must meet the duration required by local laws and regulations.


Cycle Life
Cycle life refers to the number of charge-discharge cycles that a battery can undergo. The higher the number of charge-discharge cycles, the longer the battery's life will be. For emergency lights, the battery usually remains in standby mode and only activates 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 caused by battery replacement. Among the currently available emergency light batteries on the market, lithium iron phosphate batteries have the longest cycle life. The lithium iron phosphate batteries of JUDA can achieve more than 2,000 cycles under 100% DoD (Depth of Discharge) conditions.


Safety Performance
Safety is also a factor that cannot be ignored in battery selection. Emergency light batteries should possess functions such as overcharge, overdischarge, overcurrent, and short-circuit protection to ensure that no safety accidents occur during use. Meanwhile, the battery materials should also have high thermal stability, thereby effectively reducing the risks of fire and explosion.


Charging Performance
As can be seen from the usage environment of emergency lights, power outages are sudden. Therefore, emergency light batteries should have rapid charging performance and be able to maintain the battery's charge level at full capacity all the time, thus ensuring the maximum runtime of the emergency light in the face of emergencies.


Environmental Friendliness
Environmental friendliness is an increasingly important consideration factor in modern battery selection. European countries, in particular, have a strong sense of environmental protection, which also influences their product choices. Currently, lithium iron phosphate batteries on the market are more environmentally friendly compared to other types of batteries. They do not contain heavy metal pollutants and will not cause pollution to the environment. Therefore, choosing environmentally friendly batteries is not only beneficial for protecting the ecological environment but also in line with the concept of green development.


In conclusion, when choosing suitable emergency light batteries, one should consider factors such as battery runtime, cycle life, safety performance, charging performance, and environmental friendliness, comprehensively evaluate the overall life cycle cost of the battery, and select the emergency light battery with the best cost-performance ratio.


Here, we recommend JUDA's lithium iron phosphate emergency light batteries (3.2V 3.3Ah 1S1P emergency light battery and 6.4V 3.3Ah 2S1P emergency light battery). They are equipped with 26650 lithium iron phosphate cells, which possess characteristics such as high capacity density, low self-discharge rate, long cycle life, high stability, compliance with RoHS requirements, and being maintenance-free. Meanwhile, a long float charge design is adopted to keep the battery fully charged all the time, thereby ensuring reliable illumination and safety guarantee in emergency situations.
