Claude Batteryz

Claude Batteryz shows your Claude.ai usage limits as visual progress bars right in your browser toolbar — no settings, no setup, just open the popup and see where you stand. It works silently in the background, refreshing every 5 minutes using your existing login session.

✦ Session & weekly limits at a glance — see current 5-hour window usage and 7-day model limits side by side, with color indicators that shift from blue to red as you approach the cap.
✦ Zero configuration — the extension detects your account automatically the moment you visit claude.ai, with no API keys, accounts, or sign-in required.
✦ Smart notifications — get a browser alert when usage hits 80%, so you're never caught off guard mid-conversation.

To use Claude Batteryz, you must be logged in to your Claude.ai account in the same browser where the extension is installed. Once logged in, open the extension popup and then navigate to Claude.ai Settings → Usage — this allows the extension to automatically capture your limit data from the page. After that first visit, the extension works fully in the background and refreshes your usage every 5 minutes without any further action needed.
