In response, the State Light Industry Quality Supervision and Test Center minolta np-600 battery-Ru-Kun Lin, Senior Engineer, said this happens, most likely a digital camera itself is a problem.

In general, the battery on the machine where, if not the boot, can not form a power-state, essentially no power loss, it is impossible to place a few days there will be depletion of the phenomenon of electricity; In addition, the poor quality battery materials, batteries, aging is also may result in the battery performance has dropped significantly.

“National Quality Standard for batteries self-discharge provisions are fully charged after the open-circuit state, placed 28 days, the remaining capacity of not less than 80% of the qualified, can be marketed in various brand batteries are subject to national quality testing, and is in line with the national self-discharge standard.
