Note: All batteries we supply are new from manufacturer. The batteries are charged for conservation. To be able to use it must first be charged with low current. The first charge should be at 0.3C = 22A. For initial charging of multiple cells, best to connect them in parallel and charger outputs must be connected to both ends of the parallel rows of cells.
