Referring to FIG. 9 illustrating a conventional battery 55 having a plurality of battery cells 50 therein, the battery 55 includes a bottom case 51 and a battery case separated by a top case 53 . Reference numeral 57 denotes an electrical connector for connecting the battery with the electronic device. While hydrogen generated during the discharging process is discharged into the electrolyte solution, a part of the hydrogen is discharged to the outside through fine holes formed in the battery cell 57. The hydrogen gas discharged to the outside of the battery gel eventually escapes through the plurality of holes 59 formed in the battery, as shown in FIG. 10 and FIG. However, such a conventional battery has the disadvantage that moisture can enter the battery through the hole 59 and damage the battery cell and the electronic device.
