Battery Deterioration Diagnosis

About Battery Deterioration Diagnosis
We check how deteriorated the battery is and the expected expiry left.
That shows you the ability on how much the battery can be charged.


After the Japan Earthquake, the request of checking battery capacity has increased rapidly. Electricity was cut off over wide areas at the time of the Japan earthquake in 2011.The storage batteries for emergency should have been operated during a power outage as many factories and companies had storage battery equipments. However, there were many cases that the batteries did not work as expected. After the earthquake, there are many requests for checking battery capacities from many factories and companies, even from the power companies.
