Request Battery TestingProfessional Battery Testing & Recertification
Deploying or redeploying battery packs without documented knowledge of their actual condition introduces operational risk weak runtime during critical events, unbalanced lithium-ion cell groups that create thermal hazards, and lead-acid packs with degraded capacity that fail without warning. Professional battery testing and grading measures open-circuit voltage, internal resistance, load behavior, and available capacity against referenced manufacturer specifications and customer-defined pass/fail thresholds. Each pack undergoes visual safety inspection for swelling, electrolyte leakage, terminal corrosion, and connector integrity before electrical testing begins, ensuring that physically compromised batteries are identified and segregated immediately.
OHMz-issued test reports document measured values, observed physical condition, and the final grading outcome for each battery pack, providing organizations with the data needed to make informed fleet management decisions. Packs that meet reuse criteria are labeled with test dates and returned for continued service. Packs that demonstrate marginal or degraded performance are flagged for rebuilding or replacement planning. Batteries that fail safety inspection including swelling, leakage, or severe physical damage are rejected with a documented rationale and handled according to safe disposal guidance. For IT asset managers and refurbishment operations, structured battery testing supports budget forecasting, replacement cycle planning, and regulatory compliance recordkeeping.
Common Battery Issues We Test and Evaluate
Reduced Runtime
Battery no longer delivers expected runtime - capacity testing measures actual remaining performance against rated specifications.
Voltage Sag Under Load
Battery voltage drops significantly under load - indicating high internal resistance or degraded cell chemistry.
Failed UPS Self-Test
UPS self-test failure traced to weak or failing battery packs requiring testing, grading, or replacement.
Swollen or Physically Damaged Battery
Visible swelling, deformation, or physical damage - immediate safety rejection and safe disposal guidance.
High Internal Resistance
Elevated internal resistance causing poor performance, excessive heating, or voltage instability under load.
Unbalanced Lithium-Ion Pack
Individual cell groups showing significant voltage or capacity imbalance - pack may be recoverable or need cell-level intervention.
Aged Lead-Acid Battery with Weak Capacity
Older lead-acid batteries with reduced capacity - testing determines if reuse, rebuilding, or replacement is appropriate.
Damaged Connector, Fuse, Wiring, or Harness
Physical damage to battery terminals, wiring, fusing, or connectors that may affect test results or safe operation.
Technical Capabilities in Battery Testing
OHMz Technologies performs documented battery testing - not manufacturer certification. Test results are compared against referenced manufacturer specifications and customer-defined pass/fail criteria where applicable.
Why Organizations Choose OHMz for Battery Testing
Avoid Redeploying Weak Batteries
Testing identifies degraded batteries before they are returned to service - preventing surprise failures and equipment downtime.
Reduce Unexpected UPS and Equipment Failures
Proactive battery testing catches aging packs before they cause backup power failures during critical outages.
Identify Batteries Suitable for Reuse or Rebuilding
Grading separates batteries that can continue in service from those that need rebuilding or replacement - optimizing fleet investment.

Frequently Asked Questions
It refers to documented testing, grading, and reuse qualification support rather than OEM certification or third-party laboratory endorsement.
Pricing is volume- and chemistry-dependent. A simple pass/fail survey for a small batch costs differently from detailed test-and-report work on a mixed fleet. Send the quantity and battery type for a tailored quote.
Turnaround depends on batch size, chemistry, and the depth of reporting requested. A typical small-to-medium batch can be completed within a few working days once received, with larger or mixed fleets quoted by schedule.
Lithium-ion and lead-acid families are typical, provided the battery can be received, handled, and tested safely.
In many cases yes. A zero-volt reading can be caused by a protection circuit trip rather than total cell failure. We evaluate whether the pack can be safely reawakened for testing before writing it off.
Often yes. Fleet managers use grading data to decide which aging packs still hold enough runtime for light-duty or standby roles, stretching the hardware budget without guessing.
It typically records identification, visible condition, measured values, observed behavior, and a pass, fail, replace, rebuild, or reject outcome as appropriate.
No. It is also useful for screening used stock, sorting redeployment inventory, and checking batches before shipment or installation.
Reduced runtime, voltage sag, UPS self-test failures, swelling concerns, age uncertainty, and inconsistent field performance are common triggers.
We would reassess the test parameters and application load profile. Sometimes a battery that passes a static capacity check still struggles under a peak inrush demand, and we can adjust the evaluation accordingly.
Swollen or visibly compromised packs must be disclosed upfront. Carrier and safety rules may restrict transport of physically unsafe batteries. We will advise on the safest handling path before you ship anything.
Yes. Poor battery performance can appear as random shutdowns, failed startup, unstable runtime, or false equipment fault reports.
Send the chemistry if known, model or part number, nominal voltage, quantity, age information if available, symptoms, photos, and whether the batteries are loose packs or still installed in equipment.
In many cases yes, but the preferred intake format depends on the battery type, enclosure access, and the level of testing required.
The decision is based on condition, measured behavior, practical capacity or runtime results when available, and whether the battery remains safe and useful for the intended role.
Grading reflects the state at the time of test. It cannot predict future aging or usage conditions, but it gives fleet managers a data-backed starting point for replacement budgeting and rotation planning.
It is documented in the report and can be returned, held for rebuild evaluation if applicable, or handled per disposal instructions you provide. No battery is scrapped without your direction.
Yes. A battery can show acceptable resting voltage but still perform poorly once a meaningful load is applied.
They are rejected from normal service flow and documented accordingly rather than being processed as ordinary reuse candidates.
Yes. Testing can help distinguish packs that still have value for rebuild evaluation from those that should be retired outright.
Yes. Batch testing is useful for IT asset managers, refurbishers, and UPS service programs that need documented sorting of incoming stock.
No hard minimum, but batch pricing makes the most sense beyond a handful of units. Even a small group can be quoted against the cost of guessing wrong about battery health.
Grading is a condition assessment, not a guarantee of future lifespan. However, we stand behind the accuracy of the measurements and observations recorded in the report.
Yes. Independent test data can reduce guesswork when evaluating used power assets before committing them to service.
Yes. Grading results can help separate immediate replacements from short-term spares and longer-term review items.
Yes. Handling can be aligned with customer labeling, pass-fail categories, and destination instructions once the workflow is defined.
