How to choose an emergency light battery?

As society progresses and safety awareness increases, emergency lights have become essential in various settings such as homes, offices, and public facilities. These lights provide illumination during power outages and give a guide to safety by highlighting firefighting equipment and exit routes. However, to ensure the reliable operation of emergency lights, choosing the right battery is crucial. As a professional manufacturer of emergency light batteries, PLB offers guidance on selecting the most suitable battery for your needs.

When choosing an emergency light battery, it’s essential to consider the entire life cycle cost, including maintenance expenses. Several key aspects should be taken into account:

Battery Life:

The duration for which a battery can power an emergency light is critical. Different regions may have specific regulations regarding the required duration of power supply during emergencies, so it’s important to ensure that the battery life meets these requirements.

Cycle Life:

Cycle life refers to the number of charge and discharge cycles a battery can withstand. Batteries with higher cycle life can prolong the service life of emergency lights and reduce the frequency of battery replacements. Among them, PLB’s lifepo4 battery can reach more than 2,000 cycles under 100% DoD conditions.

Safety Performance:

Safety features are essential to prevent accidents during battery operation. Emergency light batteries should have overcharge, over-discharge, over-current, and short-circuit protection functions to ensure safe usage. Additionally, battery materials should exhibit high thermal stability to minimize the risk of fire or explosion.

Charging Performance:

Given the sudden nature of power outages, emergency light batteries should have fast-charging capabilities to maintain full power readiness at all times. This ensures prompt response during emergencies and maximizes the battery’s lifespan.

Environmental Friendliness:

Environmental considerations play a significant role in battery selection. Lifepo4 batteries are preferred for their eco-friendly properties, as they contain no heavy metal pollutants and do not harm the environment.

In summary, when selecting an emergency light battery, it’s essential to consider factors such as battery life, cycle life, safety performance, charging capabilities, and environmental impact. By evaluating the entire life cycle cost, you can choose the battery that offers the best balance of performance and affordability.

PLB recommends its lifepo4 emergency light batteries, such as the 3.2V 3.3Ah 1S1P emergency light battery and 6.4V 3.3Ah 2S1P emergency light battery, which feature high capacity density, low self-discharge rates, long cycle life, stability, RoHS compliance, and maintenance-free operation. These batteries are designed for reliable lighting in emergencies, ensuring safety and security.
