XS Power Batteries was established in 2005. From the beginning we have had a technological edge because of our strong commitment to product testing. We have an in-house testing lab, we employ the services of outside accredited labs, as well as outside experts to insure we bring you the best. When we put a label on a product you can count on it. Using the highest energy density chemistry known in AGM batteries, XSP is now the battery of choice for competition car audio. With large 12V batteries as well as the 16V models, more and more records are being smashed every day with XS Power Batteries on board.
