GBM8X2 is a high-capacity spare battery designated for RX10H Extreme and RX10H Extreme LTE configurations. It is supplied as a spare battery rather than as a device configuration. This battery is available only if an RX10H Extreme or RX10H Extreme LTE SKU is purchased first. The ordering code therefore applies to deployments using one of those eligible RX10H configurations. Choose GBM8X2 when a dedicated high-capacity spare battery is required for an eligible RX10H Extreme or Extreme LTE system. The GBM8X2 ordering code identifies this RX10H High Capacity Battery (Spare).
