How to maintain UPS battery

UPS batteries are sealed acid and do not require maintenance, but there are some things that must be observed in order to increase the life of the battery. For this purpose, the following must be observed:

1- Proper charging and discharging:

One of the most important issues for batteries is charging and discharging according to the standard tables of any type of battery, which if done correctly will significantly increase the useful life of the batteries.

UPS chargers with new technology should be used. It is better to periodically check the battery voltage by an expert to ensure that the battery is fully charged and measure the voltage, charger and charging current so that the charging and discharging cycle of the battery is done correctly.

2– suitable temperature:

Another factor of battery failure is the heat and high temperature of the environment or factors that cause the battery to heat up, such as improper charging and discharging with high amperage. The ambient temperature of the battery must be between 20 and 30 degrees Celsius according to the standard listed in the catalog.

3- Connections and main batteries:

Another important issue that should be considered is the periodic inspection and visit of batteries. In each visit, make sure that the connections between the batteries are completely tight, the battery terminals (terminals) are not oxidized, and the battery is not too hot or swollen. In case of oxidation, first remove the batteries from the circuit and then completely clean the batteries with boiling water and sandpaper so that the conductivity of the batteries is completely maintained.

When cleaning the battery head, avoid contact of sulfates with clothes and skin because sulfates are acidic and will harm your skin and clothes. It is worth mentioning that by observing the above-mentioned issues, the useful life of the batteries has increased and the entire capacity of the batteries can be used optimally.

4– the same voltage of the batteries:

Considering that UPS batteries are connected in series and all batteries receive the same amount of charging current, the voltage of each battery must be measured separately in each periodic service to determine all batteries. They have the same quality. If it is determined that one or more batteries have a lower voltage than other batteries, these batteries must be removed from the circuit.

In devices that work with high direct voltage (DC), if one or more batteries are damaged, these batteries receive the same amount of current as healthy batteries. This causes damaged batteries to get very hot, and if this process continues, it can eventually lead to a fire, so voltage control is very important in every service.

5- Battery cabinet:

In order to avoid short circuit and possible impact, as well as to have a stylish appearance, you must use suitable battery cabinets. These cabinets are made in different sizes, according to the number and capacity of batteries, and they usually have rust-resistant static colors and are made of suitable alloy with standard thickness.

To install the Fiam 12FLB100 battery, we need to use a suitable battery cabinet to organize and safely store the batteries. Click on the link to get enough information about battery rack and cabinet.
