PowerBuild Batteries Private Limited, a subsidiary of Time Technoplast Limited, has received certification from the Central Power Research Institute (CPRI) under IS 1651:2013 for its OPzS stationary batteries. The certification confirms successful testing of the company’s tubular batteries housed in transparent Styrene Acrylonitrile (SAN) containers, reinforcing their suitability for critical infrastructure applications.
The certified product range includes 2V OPzS battery variants with capacities such as 10Ah, 20Ah and 300Ah. These flooded lead-acid batteries are designed to deliver long service life and reliable performance under continuous float conditions. The use of transparent SAN containers allows for easy inspection, while the tubular plate construction enhances durability and operational stability in demanding environments.
PowerBuild’s OPzS batteries are increasingly being deployed across sectors that require uninterrupted DC backup power. These include power generation and transmission facilities, substations, thermal and hydroelectric plants, as well as offshore oil and gas installations and petrochemical complexes. Their ability to perform consistently under high-load conditions makes them well suited for mission-critical operations.
Following more than six months of rigorous evaluation, PowerBuild joins a select group of Indian manufacturers capable of producing OPzS batteries with transparent containers for utility-grade applications. The CPRI certification is a key qualification for participation in utility and EPC tenders, enabling the company to expand its presence in institutional procurement and large-scale infrastructure projects.
The company noted that the new product line will be manufactured using existing facilities, with no additional capital expenditure required. This approach is expected to improve overall capacity utilization while contributing positively to operating margins. By integrating OPzS batteries into its portfolio, PowerBuild aims to strengthen its offering in the stationary energy storage segment and capitalize on growing demand from the power sector.
India’s power infrastructure continues to drive demand for reliable battery systems, with increasing focus on grid stability, backup power and renewable integration. The OPzS segment, in particular, is witnessing strong adoption due to its longevity and performance advantages, supported by replacement cycles and expansion in utility networks.
Established in 1992, PowerBuild Batteries Private Limited is a leading manufacturer of industrial and stationary lead-acid batteries in India. With manufacturing facilities in Hyderabad and Bengaluru, the company serves a wide range of sectors including renewable energy, railways, uninterruptible power supply systems and power utilities. Backed by strong quality standards and a nationwide service network, PowerBuild continues to deliver reliable energy storage solutions for critical applications.
