We have established regular training programs that include the continued education on the most advanced battery testing and ISO9001 quality assurance control system. This keeps our QC staff up to date and effective.

Our in-house QC staff is responsible for the overall quality of our products, but we have established a final QC team to assure that only the best quality products are shipped to our customers.
Minamoto conducts five main tests, namely:

1. Automated Filter Testing (defective batteries are removed automatically on the production line)
2. Appearance Test (deformation, rusty and leakage)
3. Strict discharge test (3.9ohm to 0.9V under temperature of 20)
4. Pre-shipment Checking ( AQL standard)
5. Storage Test in each months (discharge, open voltage, short circuit)

Minamoto has advanced QC equipment to test for all levels of quality such as High temperature/High humidity Test, Computer discharger, Voltage/Amperes testing Equipment apply to the quality control procedure.
