The problem people are complaining about
On Oct 22, 2026, a thread titled “Laptop shuts down on battery only, battery icon shows X after a "Battery changed" event in the battery report” reached #9 in our daily ranking of tech support problems on Reddit, and 1 other thread asked essentially the same thing. Both threads were posted in r/techsupport. Other phrasings of the same question: “Laptop battery”. BatteryTruth is aimed at that need: a free Windows utility that reads the system battery report, explains in plain English whether the battery, charger or settings are at fault, and links to the right replacement part.
Who the customer is
Laptop users, often with machines two to five years old, whose laptop switches off as soon as it is unplugged or shows a crossed-out battery icon. They have found the built-in battery report but can't interpret capacity numbers and events, and they want to know whether a new battery will fix it before paying for one or a repair.
In short, the first customer to target is: Laptop owners whose machine dies when unplugged. Start with the narrowest version of this group you can reach directly, ideally in the same communities where the problem was posted, rather than trying to serve everyone with the problem at once.
The idea

A free Windows utility that reads the system battery report, explains in plain English whether the battery, charger or settings are at fault, and links to the right replacement part.

Pricing guess
Estimate: free utility; electronics affiliate payouts per battery sold; small referral fees from repair shops. This is our estimate, not market data: treat it as a starting hypothesis and test it with real buyers before relying on it. Price anchors from the alternatives below and what people already spend on workarounds are the best reality check.
MVP you can build
Weekend: a script or small app that runs the built-in Windows battery report, parses design vs full-charge capacity and recent events, and prints a verdict with next steps. Keep the first version deliberately small: the goal is to learn whether people use it and pay, not to build every feature.
How to validate it in three steps
- Release the tool on GitHub and a landing page, and track downloads from 'laptop dies when unplugged' searches.
- Log anonymised verdicts (with consent) to see how often the battery is the cause versus other faults.
- Test affiliate links for replacement batteries for the three most common laptop brands.
Decide your success threshold before you start each step (for example, a number of signups or pre-orders), so the result actually tells you something.
Competition & existing alternatives
Windows built-in battery report (powercfg), NirSoft BatteryInfoView, manufacturer diagnostics such as Dell SupportAssist and Lenovo Vantage Before building, try each alternative as a customer would and note exactly where it fails the people in the threads; that gap is your positioning.
Risks
- Third-party batteries vary in quality; recommending bad parts damages trust.
- Free tools and manufacturer diagnostics already exist.
- Unsigned utilities may be flagged by antivirus software.
