The fire mishap on INS Sindhurakshak in Visakhapatnam that left a sailor dead and two others injured was caused by an explosion in its battery compartment, Navy officials said in New Delhi on Saturday.
Sindhurakshak, a Russian-origin Kilo class submarine, was in the Visakhapatnam harbour for a routine maintenance when the mishap occurred on Friday evening.
"It was due to a defective battery and Leading Electrical Technician Kump Dand was killed," the official said.
India had bought the 2300-tonne submarine from Russia as part of an early 1980s deal and commissioned it in 1997. It is the ninth of the 10 Sindhugosh class diesel-electric powered vessel that the Navy has in its 16-vessel submarine fleet.
"INS Sindhurakshak" is scheduled for a major mid-life refit later this year as part of a programme for this class of vessels, which began in 1997 with the "INS Sindhuvir".
In January 2008, another vessel from this class, "INS Sindhugosh", collided with a merchant vessel off Mumbai while participating in a naval exercise.
The Navy has been worried over its fast-depleting submarine fleet and by the delays in the construction of the six Scorpene submarines at the Mumbai-based Mazagon Docks and the long time taken in identifying a shipyard to order the second line of submarine construction.
