Three decades of
engineering precision.

Incorporated on 14 July 1994 in Biratnagar, Kulayan Battery Industries Pvt. Ltd. has grown from a regional energy supplier into one of Nepal's most established battery manufacturers — holding dual certifications and operating a service-integrated network across all seven provinces.

Our ISO 9001 certified production facility in Khanar-6, Sunsari operates at a capacity of 25,000+ units annually across lead-acid and emerging lithium-ion platforms. Every Kulayan battery is manufactured, tested, and supported through a unified infrastructure engineered for Nepal's specific operating conditions — voltage instability, monsoon humidity, and wide thermal ranges.

The founding directors remain operationally active alongside a team of 150+ engineers, technicians, and field staff.

Precision-built in Nepal.
Tested for Nepal's conditions.

Our Khanar-6, Sunsari facility produces over 25,000 lead-acid batteries every year. Each unit undergoes capacity, leakage, and vibration testing before dispatch.

Manufacturing in Nepal — calibrated for Nepal's voltage fluctuations, monsoon humidity, Terai heat, and Hill cold — gives Kulayan a service and performance advantage no imported brand can match. When a battery requires attention, it returns to the facility that built it.
