Abstract: Apparatuses and methods for portable storage of disposable or rechargeable batteries are disclosed. The battery holder can have several battery compartments, each being suitable for securely holding a battery of a certain size. Additionally, the battery holder has visible indicia instructing a user as to how to orient the battery in the compartment depending on whether the battery is empty or full. Thus, the orientation of the battery in the holder signals battery's empty/full status to the user. The battery compartments can be arranged in one or more rows, circularly, or in a honeycomb orientation. The battery holder can be made of elastic material capable of securely keeping the battery in place. The battery compartments for round batteries can have a non-round cross section, thus enabling air escape from the compartment as the battery is inserted.
