The Proven story is one of passion and innovation. In 1972, our founder Ohn Lwin (1949-2016) opened a battery-charging and dynamo motor repair and service shop in Mawlamyine in Southern Myanmar. Together with his wife, Mya Mya Than (now Proven Group’s finance adviser), he thereafter started a battery plate production business. In 1978, the Lwin business was moved to Yangon where it became a renowned battery plate manufacturer in Myanmar. Mr.Lwin established Proven Technology Industry Co., Ltd. a share holding company to manufacture the TOYO lead acid battery for use in cars and lighting in 1996. In 2005, he established Yangon Metal Industry Co., Ltd. the first industrial skilled secondary lead smelting plant of its kind in Myanmar. Environmentally-friendly, it recycles used lead acid batteries into refined lead or various lead alloys. In 2010, he established Proven Polyworld Co., Ltd. (formally known as Myanmar Polyworld Co.,Ltd) to produce battery plastic containers and to offer contract manufacturing and OEM plastic injection services. In 2014, Proven International Co., Ltd. was set up to distributed aftermarket automotive related parts and accessories. Committed to investing in human resources , Ohn Lwin sent his people to study relevant subjects and technical know-how. He also promoted the importance of safe working conditions. Proven Technology Industry Co., Ltd. has achieved “Best OHSNET Award” from ASEAN Occupational Safety and Health Network (ASEAN-OSHNET) in 2015. Although Ohn Lwin passed away in 2016, his legacy lives on today. His passion and innovation are the compass that points us towards the continuing success of TOYO batteries and Lion Motorcycle Batteries and the Proven Group of Companies in Myanmar and beyond.
