UPS & Power Backup
Power cuts and voltage swings can corrupt data, damage equipment and stop work. We help you choose the right UPS, size it for your load and backup time, and replace worn-out batteries, so your servers, network, CCTV and computers keep running when the mains does not.
01 / 02Pick the right protection
UPS systems
Every UPS keeps your equipment running through a power cut. Which one you need depends on how sensitive that equipment is to even a moment without power.
The power-cut test
Same power cut, two kinds of UPS
Both keep your equipment running. The difference is what happens in the moment the mains fails.
Mains power on.
Line-interactive UPS
Standby: steps in when needed
What the equipment receives
Power bypasses the UPS while the battery waits.
Online UPS
Double conversion: always in the path
What the equipment receives
Power always runs through the UPS.
The switch-over gap is slowed down here so you can see it. In reality it lasts a few milliseconds.
Standby UPS with AVR
Line-interactive UPS
A standby UPS that also corrects low or high mains voltage on its own, without using the battery.
Best for Small servers, network racks and POS systems
Double-conversion UPS
Online UPS
Every watt passes through the UPS and is rebuilt as clean, steady power, so there is no switch-over gap when the mains fails.
Best for Servers, storage, network cores and NVRs
Backup time
Li-ion battery bank
Lithium-ion (Li-ion) UPS batteries in a cabinet, sized for how long you need to keep running, and replacements matched to your UPS.
Best for Longer backup, and replacing worn-out batteries
01
LCD status
Shows load, battery level and the runtime left.
01
Double conversion
Power is converted AC → DC → AC all the time, with the battery already in the path.
01
Lithium-ion (Li-ion)
Longer life, faster recharging and a smaller, lighter cabinet than lead-acid batteries.
03
Voltage regulation (AVR)
Boosts low mains and trims high mains to keep the output steady.
03
Pure sine wave output
Stable voltage and frequency for sensitive equipment.
03
Cabinet & cabling
Batteries mounted in a cabinet and wired safely to the UPS.
02
Longer battery life
Voltage swings are handled without the battery, so it wears out more slowly.
02
Built for 24×7
Fan-cooled and designed to run continuously at full load.
02
Sized for backup time
More batteries mean longer runtime. We match them to your load.
04
Tower or rack-mount
Stands beside a desk or fits into a network rack.
04
External battery packs
Add batteries for hours of backup instead of minutes.
04
Replacement
Worn batteries swapped for new ones matched to your UPS.

Sizing & batteries
A UPS that is too small shuts down under load, and one that is too big wastes money. We work out the right capacity and battery backup for your equipment, and replace batteries when they wear out.
How we size your UPS
01
List what needs backup
Servers, PCs, network devices, CCTV recorders and anything else that must stay on.
02
Measure the load
We add up the power each device draws to find the total load in watts.
03
Choose UPS type & capacity
We pick a line-interactive or online UPS and a capacity with headroom for growth.
04
Set the backup time
We match Li-ion batteries to how many minutes or hours you need to keep running.
Our batteries
Lithium-ion (Li-ion) UPS batteries
We supply and fit Li-ion batteries for UPS systems, as new battery banks and as replacements where your UPS supports them.
Longer life
Li-ion batteries last much longer than lead-acid, so you replace them far less often.
Faster recharging
Back to full charge sooner after a power cut, ready for the next one.
Smaller & lighter
The same backup time in a smaller, lighter battery cabinet.
Built-in monitoring
A battery management system watches every cell and warns early of problems.
Get your backup time back
UPS batteries wear out with age, heat and frequent power cuts, even when the UPS itself is fine. We replace them with new batteries matched to your UPS, including Li-ion where your UPS supports it, so you get full backup time again without buying a new unit.
Signs it’s time to replace
- Backup time is much shorter than it used to be
- The UPS beeps or shows a battery warning
- The UPS shuts down as soon as the power cuts
- Batteries are a few years old or look swollen
