The DataSafe DX 4DX-5B is the first battery in the DX 4DX series. Unlike the 2DX batteries, the 4DX batteries have four cells for more power. They share the DX 2DX’s level of affordability, convenience, and reliability. The DataSafe DX 4DX-5B is a calcium flat-plate battery appropriate for high-rate UPS applications, such as large Switchgear applications and data centers. The 4DX-5B is very efficient, thanks to its four-cell construction. This battery comes equipped with an optimal grid and dual lug design, along with a heavy duty strap and plate lug. The Slide-Lock post seal is another important feature. In case of fire, a flame-resistant PVC cover protects the 4DX-5B, and an optional flame-resistant container can also be purchased.
