The 1756-BA1 ControlLogix/FlexLogix Battery Assembly by Allen-Bradley is a lithium battery assembly for the Allen-Bradley 756-L55, 1756-L61, 1756-L62, 1756-L63, and 1794-L33 controllers. Specifically, the 1756-BA1 is a Sanyo Lithium Cylindrical SE Type Cell Battery with the following battery ratings: 3V DC terminal voltage, and 1800mA of nominal battery capacity. The battery has lithium contents and uses a lead wire connector terminal. It fits into an open-style enclosure/ The 1756-BA1 has an operational temperature range of -40-60 0C, dimensions of 20 x 24 x 8 in., and it weighs approximately 17g. The 1756-BA1 should be stored at a temperature close to 30 0C. If the temperature of the part of the machine 1 inch below the 1756-BA1’s chassis exceeds 30 degrees Celsius, replace the batter within 3 years’ time (the higher the surrounding temperature, the sooner the battery should be replaced.)
