Battery & UPS testing with real performance data, not guesses.
Guardian runs your batteries through controlled load tests and records how they actually behave: voltage under load, capacity delivered, internal resistance, and thermal behavior. You get clear, data-driven answers on what to keep, what to watch, and what to retire.
From tool packs to UPS banks.
If your operation depends on batteries or backup power, you need more than “it seems fine.” Guardian’s testing is built for the real world: shop floors, small server rooms, industrial equipment, and facilities that can’t afford surprise failures.
Cordless tools & equipment batteries
Testing for high-use cordless tool packs and equipment batteries used in production, field work, and facilities.
UPS & backup power systems
Runtime-focused UPS battery testing to see how long you actually have under load, not just what the sticker claims.
Specialty & high-value packs
Specialty batteries and packs where failure means downtime, difficult access, or high replacement cost.
Simple, repeatable steps for every battery.
We follow a consistent process so you can compare results across batteries, strings, and test cycles. Every test is designed to answer the same core question: “Is this safe and reliable to keep in service?”
Baseline checks
We record resting voltage, internal resistance, and basic condition. If something is clearly unsafe or far out of spec, we flag it immediately.
Controlled load test
The battery is run through a defined load profile to measure capacity, voltage sag, and thermal behavior. For some packs, we include stress pulses to simulate real-use spikes.
Report & recommendations
You receive a simple summary: pass, borderline, or fail, plus notes on replacement, rebuild, or continued monitoring.
Batteries are cheap compared to downtime.
A weak pack in a critical spot doesn’t just cost the price of a battery – it costs time, missed work, and sometimes damage to equipment or product. Testing gives you clarity.
