GLiDERS™ are available in 22 styles accommodating small batteries, such as the CR1025 up to a 24mm CR2450 lithium cell. Several versions hold two cells in series for 6V applications. For 12V applications, four CR2016 cells can be stacked in series and are accommodated by part numbers BHX2-2032-SM and BHX2-2032-PC. GLiDERS allow batteries to be changed without tools or instructions due to the intuitive design. Built-in polarity protection eliminates the drawbacks associated with standard coin cell battery holders. The design of the GLiDERS tray prevents an electrical connection when the battery is inserted upside down. The retainer, which is made of nickel-plated phosphor bronze, has pressure contacts that offer low electrical resistance and are optimized to keep a tight, secure connection with the battery. MPD recommends that customers use a patch of nickel or gold on PCBs to act as the negative contact point. The metal retainer housing acts as the positive contact and tray retention device.
