For 45 years, Swapan Kumar Mandal has dedicated his life to keeping vehicles on the road. At 58 years of age, he continues to serve customers with the same passion and commitment that marked the beginning of his journey. Operating from his own workshop, Mondal Batteries, in Kolkata, he has built a reputation for honest advice, dependable service and long-lasting customer relationships.
Over the years, Swapan has become a familiar face for motorists who rely on him for battery services, electrical repairs, wiring, lights, horns and complete electrical maintenance for passenger vehicles, tempos and other four-wheelers. Every day, around 20 to 30 vehicles visit his workshop for battery inspections, while two to three require battery replacement or maintenance. His experience allows him to quickly diagnose problems and recommend the right solution, earning the confidence of customers who have stayed loyal with him for years.
A major milestone in his journey came in 2013, when he partnered with Tata Green Batteries. Since then, the brand has become an integral part of his business. “The quality is reliable, the batteries last longer and customer complaints are very few,” he says. He believes Tata Green Batteries stand out because of their strong performance, dependable warranty support and consistent quality, giving customers complete peace of mind. The trust he has built in the brand is reflected in the growing number of motorists who specifically ask for Tata Green when they visit his shop.
Swapan believes that selling a battery is only the beginning of customer service. He carefully checks every battery before recommending a replacement and explains the warranty coverage and proper maintenance practices to every customer. Whether it is checking the battery’s condition, guiding customers on regular inspections or helping them understand when a replacement is genuinely required, his approach is always centred on honesty rather than making a quick sale.
Although his son has chosen a different career path, Swapan continues to run Mondal Batteries with the same dedication that has defined his life for over four decades. His story is a reminder that true success is not measured by the size of a business, but by the trust earned over the years. Through hard work, integrity and the dependable support of Tata Green Batteries, Swapan Kumar Mandal continues to keep both vehicles and customer relationships running strong.
“Tata Green Batteries stand out because of their strong performance, dependable warranty support and consistent quality, giving customers complete peace of mind.”
