Power a City Batteries Catalog
Store Power safely enough to sell big without feeding every thief.
Batteries store Power until you sell it in Power a City. This catalog focuses on how storage behaves in Power Your City and how to upgrade without building a piñata for raiders.
Role in the loop
Batteries buffer Generator output. Larger buffers mean fewer trips and better use of 100KMEMBERS 2x Cash. They also concentrate value—exactly what How to steal Power players hunt.
Balance guidance: Generators vs Batteries. Ranked spends: Batteries tier list. Production counterpart: Items: Generators.
Placement basics
- Put Batteries on the sell-facing end of your spine (Best layouts).
- Keep them visible from where you stand.
- Do not hide the only vault in a dead-end maze.
- Leave space to add the next tier without tearing the whole plant down.
Defense habits: How to protect Batteries. Selling technique: How to sell Power.
When to upgrade Batteries
Upgrade when Power caps repeatedly, when Power codes overwhelm current storage, or when you want larger Cash dumps. If Batteries stay empty, buy Generators instead and review the Generators tier list.
Redeem storage-friendly boosts via How to redeem and track timers with the Boost timer. Active strings: Codes Hub.
Raid economy
Every Battery tier raises both your sell potential and your loss potential. If you cannot monitor the plant, prefer moderate storage plus frequent sells over a mega vault. After a theft, refill with Generators or a Power code rather than rage-buying random gear.
Beginner tip
Place one Battery early so you learn the store→sell fantasy immediately (How to play). Empty decorative builds teach nothing.
Storage sizing without vanity tanks
Buy Batteries because Generators are idle or because you need a larger dump under 100KMEMBERS, not because a bigger vault looks impressive. Oversized empty storage is dead Cash. Undersized storage during 1MVISITS throws away doubled Power. The catalog habit is simple: watch meters for one minute, then buy the lagging resource.
Visibility beats fancy mazes
Batteries you cannot see from your stand point will be emptied by raiders before you notice. Keep vaults on the sell-facing spine from Best layouts, and practice sell-before-leave from How to protect Batteries. If the server is aggressive, slightly smaller storage plus more frequent sells often beats one mega tank.
After a raid refill plan
- Secure or sell remaining Power at home.
- Optionally take a careful counter-raid (How to steal Power).
- Use Generators or
1MVISITSto refill (Codes Hub). - Rebuild placement if the vault sat in a dead corner.
- Return to the Items Hub before the next shopping spree.
Batteries are transferable value. Treat every upgrade as both an income tool and a risk dial.
