Zenless Zone Zero
ZZZ Battery Charge farming & efficiency
Short answer: never sit at cap; clear time-gated weeklies first; feed levels and skills on your real squad before Disk Drive gambling. Pair this with the Battery timer so overnight regen is not free progress you threw away.

How Battery Charge works
Stamina math Proxies need before arguing about Disk sets.
Battery Charge is Zenless Zone Zero’s resin / Trailblaze Power / Waveplate equivalent. It regenerates while you are offline, stops at the cap, and is spent on Combat Simulation-style farming, expert challenges, and other battery-priced modes.
- Regen: 1 per 6 minutes (default).
- Typical cap: 240 → ~24 hours from empty.
- Refills: Coffee / Battery packs are inventory items — they do not auto-update our timer.
- Events: Temporary cap raises or discount spends happen — re-read the event card and edit the timer cap field.
If you log off at 230 Battery and sleep 10 hours, you lose hours of regen. That is the entire efficiency problem this guide solves.
Recommended spend order
Maximize progress per Battery, not dopamine per Disk drop.
- Weekly / Notorious / time-gated bosses — resets do not wait for your “perfect farming day.”
- Limited-time Battery bonus events — when HoYoverse doubles drops or discounts costs, spend into those first.
- Agent & W-Engine materials for your clear squad — the 3–6 Agents that actually finish Shiyu / story / Hollows.
- Core skills you press — EX Special, Ultimate, Assist ranks.
- Disk Drive farming — correct set + main stats first; chase substats only after the squad can clear the content you care about.
Tip: spend in the chunk size shown on the entry (often 20 / 40 / 60) so leftovers do not strand you one short of a run. The Battery timer estimates how many of those chunks you have.
Avoiding cap (and waste)
Habits that recover a free day of farming per week.
- Check time to cap before long AFK stretches.
- If within ~1–2 hours of cap, burn one farming entry even if the drop is “meh.”
- Update current Battery after Coffee / packs.
- During anniversary patches (like 3.1), event overload makes capping more common — set a phone reminder for the timer ETA.
Sample weekly Battery plan
Adjust names to your live UI — the order stays.
| Day type | Focus | Notes |
|---|---|---|
| Weekly reset day | Notorious / weeklies first | Do these before any Disk spam |
| Build week | Agent + engine mats | One DPS + stun + support to soft caps |
| Skill week | Core skill materials | Prioritize buttons you press every fight |
| Disk week | One set for main carry | Stop when main stats are correct — don’t infinite farm |
| Event week | Bonus Battery modes | Override the plan while the bonus is live |
Disk Drive farming — when it is and isn’t worth it
Disks are the long tail of ZZZ investment. Early accounts feel “stuck” and blame Disks when the real issue is Agent level, W-Engine level, or missing a Stunner. Farm Disks when:
- Your clear squad is leveled enough that content is skill/gear limited, not HP limited.
- You know which set and main stats the Agent wants (don’t randomize four sets at once).
- You can afford to spend Battery without skipping weeklies.
If a single bad Disk day tilts you into capping Battery for three nights, you lost more progress than any substat would have given.
