About BattScore
BattScore is an independent battery testing project. We measure real-world capacity, publish detailed discharge curves, and track prices — so you can pick the right rechargeable battery without guesswork.
No sponsorships. No affiliate bias. Just data.How We Test
From store shelf to live discharge curves in five steps
Acquire Batteries
Purchase batteries from local retail stores and online shops to test what consumers actually buy.
Catalog & Queue
Record manufacturer, brand, and packaging details in the system. Add batteries to the testing queue.
Test on Electronic Load
Discharge each battery at multiple test currents using a professional load tester, recording thousands of data points.
Export & Upload
Export the complete test data as CSV files and import them into BattScore for processing and analysis.
Charts Are Live
Discharge curves, capacity comparisons, and pricing data go live instantly for everyone to explore.
