BatteryBar is a lightweight utility that sits in your Windows taskbar. The Free version shows a simple green bar and an estimated time remaining. The Pro version (which historically includes versions like 3.6.6) unlocks a treasure trove of data:
Version 3.6.6 (often shortened to "366" in search queries) was a stable build released in the mid-2010s, optimized for Windows 7, 8, and early Windows 10. It is lightweight (under 5MB of RAM) and famously bug-free. Many power users insist that 3.6.6 is the "last great version" before the developer shifted focus to UI modernization.
BatteryBar Pro 3.66 is useful if you want a compact, taskbar-integrated battery monitor with logging and wear metrics. For deep hardware diagnostics, pair it with tools like HWInfo or use Windows’ own battery report for periodic checks.
