Regarding Lead-Acid Batteries For Roller Shutter Doors

Roller shutter door systems are widely used in commercial and industrial facilities for their convenience and speed. The stability and reliability of lead-acid batteries, which serve as the power source for these systems, directly affect the normal operation of the rolling shutter doors. Proper use and maintenance of lead-acid batteries are essential, and timely and effective troubleshooting is also necessary when problems occur. This article will provide you with maintenance tips, model selection, and troubleshooting methods for lead-acid batteries used in rolling shutter doors.

Main Models and Application Scenarios

12V1.3AH: Compact design, often used for fire-resistant rolling shutter door controllers to ensure a quick response in emergencies.

12V2.9AH: A lightweight choice suitable for small rolling shutter doors or residential garage doors.

12V5AH: Suitable for commercial rolling shutter doors, providing sufficient starting current.

12V7AH: Typical and common model for roller gates.

24V5AH: Provides power for industrial-level rolling shutter doors that require a higher voltage.

When selecting a lead-acid battery, consider the size of the rolling shutter door, the frequency of use, and the expected backup power time. Larger rolling shutter doors or environments with frequent use require batteries with a larger capacity. For example, for commercial rolling shutter doors that need to be operated frequently, a 12V5AH or 24V5AH battery may be a better choice because they can provide stronger starting current and longer endurance.

Maintenance of Lead-Acid Batteries

Keep terminals clean: Regularly clean the battery terminals to remove corrosion and dirt, ensuring good electrical contact.

Avoid overcharging and over-discharging: Follow the battery's charging and discharging specifications to prevent battery damage.

Storage conditions: Store batteries in a cool, dry place, avoiding extreme temperatures.

Environmental protection: Dispose of used batteries in accordance with local environmental protection regulations.

Common Faults and Troubleshooting Methods

Battery leakage: Check if the battery casing and sealing gum are intact, and replace damaged batteries in time.

Battery deformation: Avoid overcharging and regularly check if the battery casing is swollen.

Short circuit: Check the internal and external connections of the battery to ensure there is no damage.

Sulfation: Regularly perform maintenance charging to avoid long-term idleness.

Performance decline: If the battery performance declines, replace it with a new one in time.

Troubleshooting Tips

Rolling shutter door will not open or close: Check if the power lines and battery connections are firm, and whether the battery has enough power.

Remote control cannot operate the rolling shutter door: Make sure the remote control battery is powered, and check if the remote control is correctly coded with the rolling shutter door receiver.

Rolling shutter door runs slowly or unevenly: Clean the door track and check if the motor needs repair or replacement.

Rolling shutter door motor overheats: Make sure the motor is not jammed by foreign objects and that it is well-ventilated.

Battery repair: For sulfated batteries, try using a small current for a long time charging method to restore its capacity.

The correct use and maintenance of lead-acid batteries are crucial for the normal operation of rolling shutter door systems. By selecting the appropriate battery model and following maintenance tips and troubleshooting methods, you can ensure the long-term stable operation of the lead-acid batteries for rolling shutter doors and provide the necessary power support in emergencies. Remember, if you encounter complex or persistent problems, it is wise to contact a professional technician for inspection and repair in a timely manner.
