Heartiley Battery follows the journey of Sofia, a brilliant science enthusiast who has always believed that love is nothing more than a mix of biology and chemistry. After witnessing fractured relationships around her – including her own parents’- she becomes determined to remove ambiguity from love. At just 16, she dreams of inventing a device that can scientifically measure love’s authenticity. Years later, at 24, Sofia finally succeeds – only to meet Sid, a comic writer who thinks her invention is absurd. A playful journey that asks one timeless question, can science ever decode the language of the heart?

Guru Lakshman said, “Sid is a character who believes deeply in emotions, instinct, and the magic of love. Playing him allowed me to explore vulnerability and humour in equal measure. Heartiley Battery is not just a love story; it’s a journey of understanding what the heart truly wants, and I can’t wait for audiences to witness it.”

Padine Kumar said, “Sofia is a character I instantly connected with – driven, brilliant, and someone who believes she can understand love scientifically. But beneath her confidence lies someone afraid of emotional instability. Playing her was both challenging and fulfilling.”

Tamil and Malayalam Zee5 Global Business Head and SVP Marketing South Lloyd C Xavier said, “Heartiley Battery is a story that beautifully captures the clash and harmony between science and emotion. Tamil audiences are always open to new concepts and heartfelt narratives, and this series offers both in a refreshing, relatable way. With this unique storytelling and a talented cast bringing these characters to life, we are excited to present a series that celebrates the unpredictability and magic of love.”
