Hefra’s activities are limited to the professional market. However, we have kept the major part of this website accessible to the general public as an additional service and support to those seeking information and advice in technical matters.
Also we would like to take advantage of every opportunity to provide information to the end user on matters of safety, health and the environment. What do the symbols on the battery pack mean, and how can I best get rid of my old battery? These questions are too important to remain unanswered. On these pages you will find the most relevant information about health and the environment.
Whoever works closely with batteries, such as jumpstarting, charging or installing a battery, is strongly advised to consult the technical pages as well. All your comments, questions and suggestions are welcome!
