How long does a UPS battery last?

Typically 3–5 years depending on environment and usage. Heat shortens battery life significantly. A failing UPS often shows warning signs: beeping alarms, shorter runtime, or warning LEDs. Replacement before failure is far cheaper than the outage it prevents.

What size UPS does an office need?

It depends on the load: a comms cabinet with a router, switch and 2–3 access points typically needs a 500–1000VA UPS; a server room with multiple servers may need 1500VA–3000VA or more. A professional assessment calculates the exact load and runtime requirements.

Why is my UPS beeping?

Continuous beeping usually indicates a failing battery or the UPS running on battery during a power cut. If beeping occurs with mains power present, the battery needs replacing — typically every 3–5 years. A dead UPS provides no protection at all.

WHAT A UPS ACTUALLY PROTECTS

An uninterruptible power supply does two jobs people consistently underestimate:

Instant power bridge — when mains fails, the UPS carries your network on battery with zero interruption: no reboots, no lost work, no dead card machines
Power conditioning — it filters the surges, sags and noise that silently damage routers, switches and servers over time

And the inverse truth: a UPS with a dead battery protects nothing. Most businesses discover this during the first power cut — the worst possible moment.

WHAT WE DO

Load assessment & sizing — calculating what your cabinet/server room actually draws, so the UPS is right-sized (not undersold, not oversized)
New UPS installation — rack or floor mounted, wired cleanly into the comms cabinet with correct earthing
Battery replacement — swapping aged batteries in existing units, disposal of old batteries handled compliantly
Fault diagnosis — units that beep, won't hold load, or drop equipment randomly — diagnosed and resolved (proven at Stanley Black & Decker, Rotherham)
Runtime testing — verifying the backup actually carries your load for the time you expect
Monitoring setup — alerts before batteries die, not after
Maintenance schedules — periodic checks so protection never silently expires
Old unit disposal — batteries and units recycled compliantly through our ITAD process

WHO NEEDS WHAT

Environment	Typical protection	Typical cost
Small office comms cabinet	500–1000VA line-interactive UPS	£150–£400 fitted
Growing office / multiple switches	1000–1500VA + monitoring	£400–£800 fitted
Server room / comms room	1500–3000VA online/double-conversion	£800–£2,500+ fitted
Battery replacement	Like-for-like, tested after fit	£80–£250

Sizing confirmed after assessment — quotes fixed before work. Runtime expectations set honestly (minutes to shut down safely vs hours of running — different needs, different budgets).

WARNING SIGNS YOUR UPS NEEDS ATTENTION

Beeping with mains power present — battery failing
Runtimes far shorter than spec — batteries aged out
Equipment reboots during brief cuts — the UPS can't carry the load anymore
Warning LEDs or dashboard errors ignored since installation
The unit is over 5 years old and has never been tested — assume the worst, verify the truth

OUR PROCESS

1 — Assessment: load measurement, runtime requirement, environment check
2 — Recommendation: correctly sized unit (or battery replacement plan), fixed quote
3 — Installation: fitted into the cabinet/rack cleanly, wired correctly
4 — Testing: simulated power-loss test — you see the runtime with your own eyes
5 — Monitoring & documentation: alerts configured, records for your maintenance file

COMMON QUESTIONS

Can you replace just the batteries? Often yes — where the unit is healthy but the battery has aged. We test before and after.
Do you take the old unit/batteries away? Yes — recycled compliantly through our ITAD/waste process.
Can a UPS protect our whole office? It protects what's plugged into it — we size and scope per environment, and integrate with generator/failover setups where they exist.
How often should it be tested? Annual testing is sensible; batteries replaced every 3–5 years. Our maintenance plans handle it automatically.
