3.4 Unmet Needs & Opportunities

• Accurate Lithium Battery Testing: Existing testers lack sufficient understanding of lithium battery (e.g., CR series, 18650) voltage characteristics, leading to inaccurate assessment or incompatibility.
  

  This is an excellent battery tester for alkaline and NiMh batteries. Remarkably simple to use, easy to read display, and, in my months of use, very accurate except for when it comes to lithium batteries. In almost all cases, it reports lithium batteries as 100% even if they're no longer working in the appliance. // The only battery I can't do is my 18650 batteries. That would make it perfect if you could do that one.

• Charge Percentage Guidance: Digital voltage is precise, but users are unclear about what voltage constitutes 'good charge' or 'needs replacement' for different battery types, lacking intuitive percentage or text guidance.
  

  Meter works well easily fit all the types or batteries... but no chart to tell you if that voltage is good or not so you will need to look that up online. That was a little annoying.

• Sturdy Build & Battery Fixation: Multiple products are described as 'feeling cheap', 'not sturdy', and batteries are difficult to fix securely during testing, affecting operational experience and long-term reliability.
  

  This thing feels really cheap and it is, but it works fairly well. // Very flimsy. Difficult keeping batteries in. // I think they work? ... they don't feel very sturdy or durable.

• True Capacity / Load Testing: Products generally only display instantaneous voltage, lacking load testing for actual remaining capacity or estimated lifespan, unable to provide true performance assessment in real-world use.
  

  This the device measures the voltage, but it doesn't do a load test this is something that advice needs very much. // This is not a tester. It doesn't apply a load.

IV. User Decision Drivers
