An apparatus and method for indicating and allowing hot swapping of a circuit board. The battery case body and said battery cover have bonding areas, respectively, which are connected by laser welding. A control switch, operatively coupled to the nitrous-oxide valve. A bed of acid neutralizing particles is contained in the support housing between the inlet port and the outlet port. The pre-biased indicator located on the base in fluid communication with the balloon is configured to provide a discrete visual signal that the pressure of a fluid in the balloon is different from a predetermined level of pressure or the volume of the balloon is different from the predetermined fill volume. Additionally, the process of the present invention includes mechanisms that allow some of the by products generated by some of the reactions, to adsorb crystallization water and reduce the humidity of the mass without using external energy.
