    • A battery pack 1 includes a battery 10, thickness detection means 11, cycle number detection means 12, and first determination means 13. The battery 10 is an alloy-type secondary battery having an electrode assembly 20 which includes a positive electrode, a negative electrode including an alloyable active material, and an insulating layer. The thickness detection means 11 detects the thickness of the electrode assembly 20 of the battery 10. The cycle number detection means 12 detects the number of charge and discharge cycles of the battery 10. The first determination means 13 determines the replacement time of the battery 10 according to the detection results by the thickness detection means 11 and the cycle number detection means 12. This configuration allows the battery pack including the alloy-type secondary battery to estimate the replacement time of the alloy-type secondary battery almost accurately, thereby enhancing the convenience of the battery pack.

    • In a charging method for a non-aqueous electrolyte secondary battery which includes a positive electrode including a lithium-containing composite oxide as an active material, a negative electrode including an alloy-formable negative electrode active material, and a non-aqueous electrolyte, a voltage of the secondary battery is detected. When the detected value is smaller than a predetermined voltage x, charging is performed at a comparatively small current value B. When the detected value is equal to or greater than the predetermined voltage x and smaller than a predetermined voltage z, charging is performed at a comparatively great current value A. When the detected value is equal to or greater than the predetermined voltage z and smaller than a predetermined voltage y, charging is performed at a comparatively small current value C. When the detected value is greater than the predetermined voltage y, constant-voltage charging is performed or charging is terminated. Here, x
