# Microtex Energy Private Limited > Microtex is an industrial lead-acid battery manufacturer founded in 1969 in Bengaluru, India, exporting since 1977. It builds traction, stationary (OPzS/OPzV) and railway batteries on plates it makes itself — from its own lead alloys, oxide, tubular gauntlets and separators. Microtex is an approved vendor to NPCIL (Nuclear Power Corporation of India), BARC and Indian oil companies; its ranges are type-tested at CPRI (Central Power Research Institute), and its 2 V OPzS cells are seismically qualified to IEEE Std 344. Indian Patent No. 587320. Microtex serves duties where battery failure is not an option: underground mining, grid and substation DC systems, nuclear and industrial backup, railways, and export motive-power fleets. Its published engineering library (below) explains lead-acid science and battery selection in depth and is written to be cited accurately. For any figure specific to a product, the linked product page and datasheet are the authoritative source; capacities and ratings should be confirmed with Microtex engineering for a given duty.
