Use And Maintenance Of Vlra Batteries
Jul 22,2020

1. VRLA Battery Selection

VRLA batteries must be correctly selected before use to ensure that the battery has enough discharge capacity to enable normal operation of communication equipment; In addition, choosing a reasonable capacity can avoid the waste caused by choosing too large capacity.

There are two types of selection methods:

1) calculation method.

2) curve search method.

2. Installation And Use Of VRLA Batteries And Precautions

Before installing and using batteries, first read the product instructions carefully and install and use as required. During installation, special attention should be paid to the following aspects:

1) The installation plan shall be made according to the location and conditions, such as ground load, ventilation environment, sunlight exposure, corrosion and organic solvents, layout of the machine room, convenience of maintenance, etc.

2) The new and old batteries generally cannot be mixed during installation. Different types of batteries or batteries with different capacities should never be mixed.

3) The battery is 100% charged and discharged from the factory. It must be handled carefully to avoid short circuit. Insulating tools and gloves should be used in installation to prevent electric shock.

4) Before installation and use, the battery shall be stored at an environment of 0 ~ 35℃ for 3 months. If it exceeds 3 months, the battery shall be replenished according to the standard specified in the book of use.

5) Connect the battery connection between columns, floors and panel terminals according to the specified serial and parallel lines. Before installing the terminal connector and the conduction of the entire power system, check the positive and negative polarity and measure the system voltage carefully. Note: on the premise of conforming to the design cross-sectional area, the outlet line should be as short as possible to reduce the pressure drop during large current discharge; When more than two groups of batteries are connected in parallel, the cable from each group of batteries to the load should be the same length to facilitate the balance of battery current in each group when the batteries are charged and discharged.

6) When the battery is connected, the screws must be tightened, but also to prevent the pole pole from being damaged due to excessive tightening force.

7) After the installation, the voltage of the system and the positive and negative directions of the battery shall be checked again to ensure the correct installation of the battery.

8) Clean the battery case, cover, panel and connection wire with a soft cloth soaked in soapy water. Do not clean the battery cover and other parts with organic solvent.

3. VRLA Battery Maintenance

1) The placement of valve-controlled sealed lead-acid batteries

Valve-controlled sealed lead-acid batteries need not be specially equipped with a battery room, but can be installed in the same room with communication equipment. Can be stacked in combination or mounted on a battery rack.

2) Frequently Checked Items

A. Floating charging pressure, ambient temperature;

B. Whether the joint is loose or corroded;

C. Whether there is leakage and deformation of the battery shell;

D. Whether there is acid mist overflow around the pole and safety valve;

3) Supplementary Electricity

A. After the battery system is installed, replenish the battery pack;

B. The battery shall be put on hold for more than three months;

4) Periodic Maintenance Projects

Monthly Maintenance

Complete the following monthly checks:

1. Keep the battery room clean and hygienic;

2. Measure and record the ambient temperature in the battery room;

3. Check the cleanliness of the battery, damage and heat marks of terminals, damage or overheating marks of the shell and cover one by one:

4. Measure and record the total voltage and floating charging current of the battery system;

Quarterly Maintenance

1. Repeat each monthly inspection;

2. Measure and record the floating charging voltage of each online battery. If there are more than two batteries whose voltage is lower than 2.18V after temperature correction, please contact the manufacturer.

The Annual Maintenance

1. Repeated quarterly maintenance and inspection;

2. Check whether the connection part is loose every year;

3. The battery pack shall carry out a check discharge test with actual load every year, releasing 30%-40% of its rated capacity;

Three Years Maintenance

Capacity tests shall be conducted every three years and once every six years after use. If the battery's full discharge capacity is less than 80% of the rated capacity, the battery life shall be considered to be terminated.
