Cucumber Battery is a passive item in Reverie: Make Good Omissions, a mod for The Binding of Isaac.

When charges can be gained, if Isaac has no active item or if his active item cannot gain charges as a result, the gained charges will be stored as extra charges.

In any situation where charges are gained, if the charges exceed the amount needed to use the active item, the excess charges will be stored as extra charges.

Charges gained from Battery Bum will not be stored as extra charges.

The effect of fully recharging Isaac's active item is considered as adding 24 charges to Isaac's active item.

Isaac can pick up batteries under any circumstances.

Up to 999 extra charges can be held at a time.
