Measured laboratory data

Battery Archive — cycling studies

Voltage curves, cycling conditions and capacity-fade comparisons across research studies.

Use it for
Study how test conditions affect degradation. Research cells do not establish the runtime of a particular commercial UPS.
Operating conditions
Match chemistry, cell size, temperature, current profile, voltage limits and cycle protocol. Compare capacity measurements only on a compatible test basis.
Where & how to access
Public visualization and study descriptions; the site requests an email inquiry for complete cell CSV files. Check study-specific reuse and citation terms.

Usage terms & attribution

Follow the selected dataset’s license, required citation and contributor notices. If redistribution terms are not explicit, ask the publisher before reusing files. This page provides links only.

Measured laboratory data

NASA PCoE — battery datasets

Battery experiments including charging/discharging at different temperatures and aging studies.

Use it for
Select the relevant battery experiment from the repository and preserve its test protocol and dataset citation.
Operating conditions
Keep the selected experiment’s cell identity, charge/discharge protocol, temperature, cutoff voltages and aging history; retain missing records as missing.
Where & how to access
NASA lists dataset descriptions and download links; availability varies by entry. Review each dataset’s documentation and reuse terms.

Manufacturer battery performance

EnerSys — PowerSafe technical documents

Product guides, performance documents and installation information for PowerSafe standby batteries.

Use it for
Find discharge information for a specific battery model before sizing a backup bank.
Operating conditions
Match the exact model, constant-current or constant-power basis, duration, end voltage per cell, temperature and document revision. Apply the selected system’s aging and conversion-loss assumptions separately.
Where & how to access
Open the product’s Downloads section and select its performance document. For other chemistries or ranges, use the relevant EnerSys product page or technical representative.

Manufacturer system-runtime reference

Eaton — UPS runtime graphs

Load-versus-runtime references for Eaton UPS products.

Use it for
Check a complete UPS and battery configuration rather than treating cell capacity as delivered AC runtime.
Operating conditions
Match load in watts, internal/external battery configuration and the curve’s battery assumptions. Check ambient temperature, battery age and load power factor in the applicable product documentation.
Where & how to access
Select the UPS family and configuration on Eaton’s runtime page. Use the regional product page or support team for a model not listed.

Measured laboratory data

University of Maryland CALCE — battery research

Battery cycling, storage and characterization experiments with supporting publications.

Use it for
Study capacity change, state-of-health methods and test-protocol effects; these research cells are not a commercial UPS qualification.
Operating conditions
Check cell chemistry, format, temperature, charge/discharge limits, current profile, rest periods and aging history. Keep calendar aging separate from cycle aging.
Where & how to access
Choose a dataset on the Battery Research Data page and read its experiment description and related papers before following the file links.
Open source ↗
Usage terms & attribution

CALCE asks publications using its data to cite the articles describing the experiments. Check any additional dataset terms; citation alone does not establish unrestricted redistribution permission.

Practical use

For a backup-runtime study, use the selected battery’s discharge data at the intended load and cutoff voltage; apply the manufacturer’s temperature and aging factors. Use laboratory cycling data to study degradation, not as a replacement for the selected UPS battery’s ratings.

Check before using the data

  • Match chemistry, cell or module configuration, current or power, cutoff voltage and temperature.
  • Distinguish constant-current from constant-power discharge, and include UPS conversion losses where applicable.
  • Use the exact battery and UPS manufacturer documents for final runtime and compatibility checks.

Put the data to work
