High-rate VRLA UPS Batteries from Standby Systems

The ELITE batteries that are offered by Standby Systems are mostly VRLA (Valve Regulated Lead Acid) batteries which are suitable for use in various applications such as:

 Riello AROS tower or rack mount UPS (uninterruptible power supply)
 Single-phase Sentinel Dual and Sentinel tower UPS
 Three-phase Riello MPS and MHE UPS
 Telecoms Gel batteries for chargers
 Emergency lighting backup
 7 and 9 AH Alarm systems
 Access control systems

The ELITE VRLA battery range is available from 5AH (amp hour) up to 3000AH in 2, 6, and 12-volt versions. This battery is a high-rate battery designed to give ultimate performance in a particular size housing rather than cycle life.

It is available in a 3 to 5-year design life battery from 5AH up to 33AH with a cycle life expectancy of 50 to 150 discharges or, alternatively, in a 10-year design life battery from 40AH up to 3000AH with a cycle life expectancy of 150 to 300 discharges.

The ELITE Lead carbon battery is available in a 12-volt 50AH or 100AH block and is suitable for cycling applications such as regular load shedding, solar, and off-site inverter applications. The lead-carbon battery can also be used in a UPS system which is subject to daily cycling, provided the UPS has the correct recharge voltage and current abilities to recharge the battery before the next discharge. The lead-carbon is a high-cycle battery offering over 2000 discharges in its service life.

UPS and Battery Specialists

At Standby Systems, our team of highly skilled electrical engineers have all specialised in the emergency power field (in particular UPS systems and batteries) for most of their working careers. They can assist with any UPS, inverter, or battery application for emergency backup, be it the design and commissioning of new systems, repairs and maintenance, or replacement of the various consumable parts, such as backup batteries, capacitors, or fans, all of which have a limited service life and eventually fail in the mid to long term due to fair usage.

Our teams of highly skilled UPS specialists are supported by an ample infrastructure with a national footprint from Riello UPS and VRLA battery warehousing, logistics, rigging, installation, commissioning, and ongoing spare parts availability and support to ensure your critical load remains working during power interruptions.

As the storage temperature of a lead acid battery has a big effect on its self-discharge, with more frequent refresher charging being required for batteries stored at temperatures above 20 degrees Celsius, all of Standby Systems battery storage warehouses are fully airconditioned to keep the batteries cool for long storage time between recharges and to keep the batteries in top condition. All these facilities include state-of-the-art charging bays using AROS RIELLO MPS UPS units which have big powerful rectifiers for efficient and powerful recharge of any battery bank.

UPS and Battery pairing

The heart of any uninterruptable power supply system is its battery. Without a battery, a UPS can’tperform one of its key functions, which is to keep the load up and running when the power goes off. This makes the battery a critical path single point of failure in a UPS system, and thus it is very important to ensure that the battery is kept at optimal performance at all times under the most ideal operational environment. To keep this consumable product at optimum means:

Proper sizing according to the application for float or cyclic discharging.
20 to 22 degrees Celsius operating environment all the time.
Regular preventative battery maintenance.
Sufficient air movement around the cells for efficient cooling.
Regular battery cell impedance measurement to try to predict any signs of failure to replace before failure and prevent inverter load disruptions.
An effective battery monitoring system for 24/7 monitoring of all cells connected to your UPS.

Some UPS battery technologies can operate at much higher and lower temperatures than a standard lead-acid battery vented or sealed or semi-sealed type technology. For example, a nickel-cadmium and lithium battery (Lithium Ion and Lithium Iron Phosphate LiPHO4) can operate at up to 50 degrees Celsius provided the temperature is again calculated into the UPS system design and type of application, be it occasionally used in conjunction with a standby generator set or cycle discharge.

It is important to note that a VRLA battery will offer reduced performance at temperatures below 20 degrees Celsius and accelerated performance with much-reduced service life in the field at temperatures above 22 to 25 degrees Celsius.
