Know what you've got left using critical power.

WattBattery is a clean, glanceable read of your remaining hard-effort capacity — shown as a simple battery on your Edge. The harder you push above your sustainable power, the faster the battery drains. Ease off and it recharges.

Two layers of information at a glance:
- Battery fill — how much capacity you have left (green/amber/red)
- Battery outline — what state you're in right now (red = depleting, green = recovering, black = steady)

Display mode is your choice:
- Percent (default) — classic W'balance remaining
- Time — seconds-precise time to empty when you're depleting, time to recover when you're rebuilding

Use it to:
- Time attacks — know whether you can go again
- Pace climbs — control your battery to the top
- Don't blow up — read the warning before you crack
- Train smarter — dont start that next interval until you recovery

Two essentials to enter once:
- Critical Power (CP) — the highest power you can sustain without fading
- W' (in kilojoules) — the size of your above-CP battery

Optional settings:
- Display Mode — percent or time
- Recovery Target — 90%, 95%, or 99% W' (when to consider yourself "recovered")
- Smoothing — 5 or 10 seconds

Built on the well-validated Skiba (2012) model also used by Golden Cheetah, WKO, and Xert. Numbers display inside the battery for clean readability at any size. Adapts to 1-up, 2-up, 4-up, 6-up Edge data screen layouts. Greys out cleanly when no power meter is connected. State persists through pauses, auto-pauses, and Edge restarts.

Made by Enhanced Endurance — coaching cyclists who fit training into real life, not the other way around.
