Description: The Disposable Enchanted Cell Phone Battery appears like an ordinary battery for a modern-day cell phone, but it bears subtle mystical markings and emits a faint magical aura. Each battery is a one-time use item, activated upon insertion into a compatible phone. Once activated, it provides temporary magical abilities that enhance the functionality of the phone. 

Spiritcall Battery: This battery allows the user to establish a temporary connection with the spirit world. When activated, it grants the ability to send text messages to the realm of the deceased, functioning similar to the spell "speak with dead." The user can ask a limited number of questions, and the answers will be received as text messages from the departed spirits. The effects of this battery would last for a specific duration before the enchantment fades. 

Elemental Resonance Battery: Inserting this battery imbues the phone with elemental powers. It grants the ability to send messages that harness elemental energies, such as a fiery text message that deals fire damage, an icy message that slows down the recipient, or a gusty message that knocks back enemies. The effects would be limited and aligned with the chosen elemental theme. 

Illusory Messenger Battery: This battery allows the user to send illusionary messages that create visual or auditory illusions for the recipient. The illusions could be used for stealthy communication, distraction, or misdirection. The illusions created would be limited in complexity and duration, designed for covert or deceptive purposes. 

Knowledge Seeker Battery: Activating this battery temporarily grants the user access to a vast repository of information and knowledge. When using the phone, the user gains proficiency in specific knowledge-based skills for a limited time. It could provide bonuses to research, investigation, or specific areas of expertise, effectively granting a temporary boost to the user's intellectual capabilities.
