This is a new RAM3GL 9.6 Volt 3.0 amp hour battery for Greenlee EK425 crimpers. If your batteries will no longer hold a charge replace them with the OEM batteries and breathe new life into your tool.
The first generation tools had a 1.3 amp hour battery. These replacement batteries hold a charge much longer. Also Ni-cad batteries have a somewhat short life span so if your batteries are more then a year or two old they will not take a complete charge.
Please note this is a Ni-Cad battery for the older style EK425 crimpers and will not work with the newer Lithium battery powered tools.
