Can Car Battery Be Used in a UPS.? – Complete Guide
Nowadays, people are troubled due to UPS battery backup. Due to this, people think of ways to increase the battery backup of UPS. You must have often heard from people that by putting a car battery in a UPS, the battery backup of the UPS will increase. But can it really increase the backup of UPS by putting car battery in UPS? Below is the information explained in detail what will happen by putting car battery in UPS.
Key Points: Car Battery vs. UPS Battery
Before you think of using a car battery in a UPS, you need to understand the difference between the two.
Car Batteries: High Cranking Power
Created to produce a huge burst of energy within a short period of time in order to start the engine, car batteries are. They offer high cranking amps, which is the measure of how much current they can provide to commence the vehicle operation. Normally, car batteries are lead acid types of batteries that have been designed for the high discharge rates and not meant for deep cycle charges.
UPS Batteries: Deep Cycle and Steady Power
In contrast, UPS batteries are typically characterized as deep cycle batteries, meaning they are specifically built for delivering constant power over a lengthy time. They can withstand many deep discharge cycles and hence are apt for different types of electronic equipment given that they ensure continuous electricity supply even in cases of power failure.
Can You Use a Car Battery in a UPS?
The simple answer is yes, but you cannot use it directly in UPS. There are a few things you should keep in mind, which are mentioned below.
Voltage Compatibility
12V batteries are used in most UPS systems, and cars also use 12 volt batteries. However, it should not be forgotten that just having the right voltage does not ensure perfect integration. The more important issue is to ensure that power can be obtained from the battery for a long time without any change in the output voltage.
Discharge Characteristics
Car batteries are not meant to be deeply discharged. If used in a UPS, a car battery may fail early because of the constant cycle of being discharged then recharged. The reliability and durability of the deep cycle UPS batteries may not be availed when ordinary car batteries are used in their place.
Safety Concerns
Placing a car battery in a UPS presents numerous dangers. A car battery may produce hydrogen gas that is highly combustible. Good ventilation is necessary to avert explosion risks. Additionally, car batteries do not have safety features similar to those of UPS batteries, and this raises the chances of heating up excessively and leaking.
Potential Benefits and Drawbacks
Benefits: of Using Car Battery in UPS
If we compare the price, UPS battery is more expensive than car battery, so you will have to spend less if you choose car battery and UPS battery is not easily available in shops. And you can easily get car battery in any shop.
Disadvantages: of Using Car Battery in UPS
There are also disadvantages of using the car battery in UPS, which are as follows.
Reduction in Lifespan:It can be noted that many doings of deep discharge in a UPS have the potential of significantly shortening the life of a car battery.
Risks to Life: In view of the fact that the lack of special safety features in car batteries may lead to emission of hydrogen gas; using them in UPS devices would be such a dangerous choice.
Unstable Power: An unstable power output caused by car batteries may result in harmfulness to electronic devices that are very weak.
Steps to Use a Car Battery in a UPS
You have to decide whether you want to use a car battery in a UPS despite all these disadvantages. And if you want to use a car battery in a UPS, then follow these steps to minimize the harm caused by the car battery:
Control Voltage Compatibility
To use a car battery in a UPS, you must select the car battery according to your UPS battery voltage. Most UPS use 12 volt batteries, but you should still check the UPS battery voltage. If your UPS has a 12 volt battery, then choose a 12 volt car battery.
Install Proper Ventilation
Prevent hydrogen gas build-up in the blister by installing the car battery in a well ventilated area. You can alternatively use a battery box which channels out the gases through a vent.
Use 12v Battery Charger
Your UPS cannot charge a large car battery. You can connect the battery directly to the UPS, but the UPS can only charge the car battery up to the capacity of the UPS battery. So you will need to install a separate 12 volts charging to fully charge your car battery.
Monitor Battery Temperature
For the purpose of avoiding overheating, the temperature of the battery has to be checked frequently. Battery failure can result from the overheating, and this presents a threat to safety.
Test Backup Duration
Check the duration of a backup that is supported by a car battery. Examine to ascertain if it will cater to your needs by ensuring that there is power on all essential appliances when electricity goes off.
Alternative Solutions
If you find using a car battery in a UPS too risky or impractical, consider these alternatives:
UPS Built-in Battery Replacement
Many UPS are designed to enable a simple change of battery in case it goes bad. To save time and be sure the batteries are correct ones, then you should consider buying a UPS which has this facility as well.
Use Deep Cycle Batteries
Consider utilizing UPS system’s deep cycle batteries which are specifically designed for this purpose due to their long discharging capabilities making them very reliable.
Use Lithium-Ion Batteries
In UPS systems, lithium-ion batteries are increasingly favored because of the long lifespan and efficient power delivery they have. Though they are more costly, they serve as a reliable and safe alternative to lead-acid batteries.
How To Increase UPS Battery Backup
If you want to increase your UPS backup, then you should follow the steps given below. To increase the backup, we have told you some important things below.
Decrease Electricity Consumption
Unplug Useless Devices: Remove all devices that do not play crucial roles during a power break.
Employ Energy-Efficacious Gadgetry: Use energy-friendly appliances instead of high power consuming ones.
Regularly Attend To The System
Keep Clean of The Battery: Make sure that there is no dust or corroded parts at the battery terminals.
Check For Battery Health: Always conduct tests on its voltage status and ability to store charge overtime
Make Adjustments To Configurations
Adjust UPS Settings: Setup UPS such as that it does not support all devices, hence reducing energy use generally.
Put Off Power Conservation Modes: Turn off power-saving options on connected apparatus.
Make Sure The UPS Is Well Ventilated
Ensure Adequate Airflow: Remember to keep UPS where there is enough air circulation that deters overheating.
Stay Away From Direct Sunlight: Remove any heat sources from the UPS which reduce battery efficiency.
Do Regulate Charging Cycles
Keep Battery Energized: Never should the battery be abandoned such that it loses all its strength while charging after every use will help in prolonging the life of that system.
Carry Out Discharge Experiments: It is recommended that you should sometimes let the battery get totally discharged first and then charging it again in order to realign its capacity.
Upgrade The Battery
Go For Higher Capacity Batteries: You may want to switch over to bigger capacity cells, given that these are supported by your UPS.
You Might Prefer The Lithium-Ion Battery: Such batteries have a greater span and give more efficient power.
Temperature Management
Normalized Operation Temperature: The best working temperature range for batteries is between 20-25 °C (68-77 °F).
Eliminate Extreme Temperatures: Too hot or too cold climates can kill the battery faster.
Monitor How The Resources Are Being Utilized
Use Power Monitoring Tools: In order to determine what causes a high load, monitor the power usage.
Synchronize The Device Utilization Timetable: Implement a power scheduling that allows intensive tasks during specific timeframes when there is no need for backup supply.
