Tell us about your battery:
Stop Guessing. Know If Your Batteries Will Hold.
Real-world battery & UPS testing with clear pass/fail results and data you can act on.
BATTERY & UPS TESTING WITH REAL PERFORMANCE DATA, NOT GUESSES.
-
We give you the data to:
Catch failures before they happen
Avoid unnecessary replacements
Keep critical systems running without interruption
-
WHAT YOU ACTUALLY GET:
Actual capacity (how long it really runs)
Voltage under load (not just idle readings)
Internal resistance (hidden performance killer)
Thermal behavior (how it handles stress)
Output Callout (highlight this visually):
Final Result: PASS · BORDERLINE · FAIL
-
WHAT MAKES THIS DIFFERENT:
Real load testing—not surface-level checks
Thermal tracking to identify risk
Consistent process across every battery
Built on our proprietary Battery Analyzer system
If it can’t perform under load, it’s not reliable. We prove it.

We Test Batteries the Way They’re Actually Used
Most “testing” is just a quick voltage check. That doesn’t tell you anything about real performance.
We run controlled load tests that simulate actual usage—so you know what will happen when it matters.
How it works
Step 1
baseline check
We identify obvious issues voltage, resistance, and safety.Learn More
Step 2
Load Testing
We simulate real use to measure capacity, voltage drop, and heat.
Step 3
Clear results
You get a simple answer: keep it, monitor it, fix it or replace it.
One failed battery in the wrong place can shut down operations, delay jobs, and damage equipment.
Testing gives you control.
Replace only what actually needs replacing
Prevent failures before they happen
Make smarter repair or upgrade decisions

Paid Battery Performance Testing
For customers needing more than a basic evaluation, Guardian offers advanced battery performance testing with measured capacity, load behavior, voltage sag analysis, and a written report.
Testing includes:
Safety screening
Visual inspection
Pack & charger voltage checks
Port checks
BMS output testing
Accessible cell-group voltage checks
Internal resistance screening
Controlled load testing
Full capacity testing
Written recommendations & data reporting
This service helps determine whether a battery is performing near its rated capacity, failing under load, or if repair, rebuild, or replacement is the best option.
Repair or rebuild work is quoted separately.
