November 16, 2025: South Korean company Repowertek is seeking joint venture partners and investors to expand deployment of its innovative lead battery regeneration technology in global markets.
Repowertek claimed on November 5 its ‘PRIME Series’ solution is the first to feature technology capable of regenerating lead-acid batteries without internal overheating.
A proprietary high-frequency pulse algorithm ensures stable battery performance for up to 10 years while preventing overheating or degradation, according to the company.
A spokesperson said PRIME, inspired by automotive maintenance practices, incorporates scheduled restoration cycles.
“After initial regeneration at roughly two-thirds of a battery’s service life, follow-up treatments every 12-18 months restore capacity, reduce total ownership costs, and maintain fire-free operation over the battery’s extended lifespan.”
With regular maintenance and the use of a regenerator, lead acid batteries can achieve up to three times the lifespan of typical use, the spokesperson said.
The proprietary technology also offers a safer, more economical alternative to lithium based energy storage systems and combats what Repowertek said are growing global concerns over Li battery fires and “lithium fire phobia”.
“Amid intensifying global competition in energy storage, lithium ion batteries are increasingly considered ticking time bombs, prone to fire, thermal runaway, and toxic gas emissions.”
Repowertek said after more than a decade of R&D and several product generations to date, it has already exported PRIME to over 70 countries.
The system safely and repeatedly restores industrial lead acid batteries for ESS, UPS, and traction applications across sectors such as telecoms, datacenters, hospitals, shipping, railways and defence.
The system integrates battery subscription and leasing models, PRIME maintenance services, equipment rental, lead recycling, and strategic partnerships with manufacturers, creating recurring revenue streams and a fully circular, sustainable closed-loop ecosystem.
