Volt

Volt sits in the notification area and reads your laptop's battery every minute. It shows how much of its original capacity the battery still holds, how that is changing month by month, and how long a charge actually lasts with the way you use the PC.

What it does

Battery health at a glance: full-charge capacity as a share of the design capacity, the cycle count, and a plain verdict of Good, Worn or Replace soon.
Capacity over time, so wear shows as a trend across weeks and months rather than a single number.
Charge level and power charts for today, 7 days and 30 days.
Every charge and discharge session: when it started and ended, how long it lasted, how far the charge moved and the average watts.
Real-world battery life, worked out from your own last 7 days on battery.
Notifications when the charge reaches an upper limit (unplug now), falls to a lower limit, or health drops below a level you choose. Each can be switched off.
Light and dark mode, and export of readings, sessions and capacity history to CSV.

Good to know

Free to try for 14 days with every feature. After that Volt needs a licence to keep running; without one it stops, and what it has recorded is kept for when you enter a key.
Volt needs a PC with a battery. On a desktop it has nothing to read.
It records only while it is running, so let it start with Windows. Nothing is recorded while the PC is asleep or off.
Capacity and cycle count are whatever the battery reports to Windows. A few batteries do not report a cycle count; Volt says so rather than guessing.
It installs for your user account only and never asks for administrator rights. History stays on your PC and is never deleted.

One-time purchase for one PC. Includes every version released in the following 12 months; the version you have keeps working after that.
