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.
