PROBLEM TO BE SOLVED: To easily dismount a secondary battery from a mounting position from the lower side without applying much force to a finger by forming holes commonly penetrating through upper and lower lids and a charge circuit board. SOLUTION: A recess 3 allowing mounting of two secondary batteries 2 is formed in an upper lid 1, and holes 5 are formed on the part of the recess 3. Holes 8 are formed in a charge circuit board 7 at the corresponding positions and in the common size to the holes 5 of the upper lid 1. Additionally, holes 10 are formed in a lower lid 9 at the corresponding positions and in the common size to the holes 8 of the charge circuit board 7 and the holes 5 of the upper lid 1. When the secondary battery 2 mounted in the recess 3 is dismounted from the charger composed like this, the secondary battery 2 can easily be dismounted by passing a finger through the hole 8 of the charge circuit board 7 from the lower side of the hole 10 of the lower lid 9, thereafter by abutting the finger on the loner side of the secondary battery 2 from the hole 5 of the upper lid 1 and then by raising the secondary battery. |
