Battery Check - coming soon
After a surge a lot of batteries lock themselves or the fuse trips while the cells are still fine, and the battery goes in the bin. Battery Check reads the battery's own chip and tells you why it does not charge, so you know if the battery is really the fault before a new one is ordered. A free app for Windows.
How it works
Battery Check reads the battery's own chip and says why it won't charge.
Coming soon on the Microsoft Store.
1 · Connect the pack's SMBus pins - SDA, SCL and GND - to the PC
What it will do
- Reads the pack's own gauge chip: health, charge cycles, every cell, temperature - and why it stopped charging.
- 2-, 3- and 4-cell packs: every cell green, amber or red against safe limits.
- A plain verdict: worn, cells out of balance, deeply discharged, locked, too hot or too cold - or the battery is fine and the laptop is at fault.
- Can't judge? It says so. If a battery doesn't answer properly, you get "can't judge this battery" instead of a guess.
- It only reads: it never writes to the battery, never clears a lock and never charges.
- Reads the laptop's charger chip too (TI bq24780S / bq24725A, Renesas ISL9237 / ISL9238): what the board is asking for.
- Everything stays on your PC - a one-page report, nothing uploaded.
For trained technicians - lithium batteries can catch fire if their pins are shorted. Needs a small USB-SMBus adapter. Not affiliated with any battery or chip maker; their names only describe what the app can read.
Free, private, built to keep devices alive
In 15 years at the bench we saw too many good devices go in the bin because nobody found the real fault. Our Hardware Specialist and Senior Repair Technicians built these tools so more devices get fixed instead of thrown away. If they helped you, a review helps the next person find them, and your support pays for the next fix.
> goal: Less e-waste · Greener Earth
We find the real fault before parts are replaced, so fewer working batteries, boards and devices end up as e-waste.
