An uninterruptible power supply or uninterruptible power source (UPS) is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.

A UPS is typically used to protect hardware such as computers, data centers, telecommunications equipment or other critical electrical loads where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss. UPS units range in size from units designed to protect a single computer without a video monitor (around 200 VA rating) to large units powering entire data centers or buildings.

If you cannot periodically charge your UPS battery while in storage, most experts recommend storing your battery in cooler temperatures – 50°F (10°C) or less – which will help slow down the degradation of your battery.
The main reason for this is the deterioration of the battery contacts. Constant discharging of batteries will cause them to reach their end of life prematurely. Short UPS activity due to compensating for swells and sags should be considered as battery discharge cycles. If you don't look after your UPS batteries they're much more likely to fail.

Look for evidence of corrosion
Batteries are one of the least technical components in your UPS, yet one of the most critical. They are electrochemical devices that require regular checks to ensure safe and proper operation.
During preventive maintenance visits try to minimize battery-related UPS failures by performing a complete visual inspection in which the technicians should do the following: Look for evidence of corrosion and Check the appearance and cleanliness of battery, rack/cabinet, and battery room. Remove dirt accumulation on the top of jars and Inspect for cracks, leaks, or bad cells, and check connection torques and Re-tighten battery connections per manufacturer’s specifications (if needed).
A variety of critical battery parameters are measured and recorded during preventive maintenance visits. These measurements include: Total float voltage and charging current, Overall AC ripple voltage and current, Ambient temperature, Temperatures, float voltage of all individual jars, Connection resistances, All internal ohmic readings

There are PROS and CONS depending on each case. This is why it is critical before performing a UPS installation to analyze the following variables: Battery technology, size, quantity, location, hazards, electrical considerations, accessibility, seismic considerations, temperature.
We are ready to advise you on the protection design of your critical load, do not hesitate to contact us.

The objective of performing preventive maintenance on our protective equipment is vital since in this way we are proactive anticipating any event and contributing to a longer useful life (we can make an analogy when we go for example every year to get a medical check-up to prevent or detect abnormalities early, for example, in our immune system).
When hiring a services company for preventive maintenance it is important to require that they have a Software platform where we can access to see the maintenance reports, calendars, indicators, histories, recommendations, to be able to contact in case of emergencies, etc.

In places where there is no physical space, when there is little server load, applications that need rapid implementation (1 week) and where it is necessary to save on infrastructure.
