The scientific productivity of lead-acid batteries-related research among researchers, countries, institutions, journals, and subject area’s was investigated by a bibliometric analysis of lead-acid batteries research from 1980 to 2014. The search includes the Web of Knowledge and SCOPUS databases with the word lead-acid batteries in the title. From Web of Knowledge 2102 documents were obtained, whereas a total of 4685 documents were obtained from SCOPUS. More than 58% of the documents are research articles, mostly (more than 92%) written in English, about 20% produced in the United States and 20% produced by Chinese researchers. The study reveals the most productive institutions and authors. Most prolific author is Detchko Pavlov from Bulgarian Academy of Sciences, who account for 1% of the published articles. Journal of Power Sources is the main journal most used for leadacid batteries research publications (more than 32% in WoS and more than 20% in SCOPUS). According to this results it can be concluded that there is an important gap identified between developed and developing countries in the volume of scientific papers. About the 30% of the papers have been published by the 10 most developed countries excluded Taiwan.
