1. Use reasonable formula MF of lead-calcium alloy
A reasonable formula of lead-calcium alloy was prepared by utilizing the rich experience of battery manufacturing in Japan. Generally, traditional batteries have fast self-discharge and high water loss, which need to be maintained regularly. YUASA's MF series uses reasonable lead-calcium alloy formulation, which can effectively improve self-discharge and water loss, and achieve low maintenance effect.
2. High Safety Design
MF series batteries are designed with double safety designs of white cell and electric eye (indicator). The white cell can see through the battery water level inside the battery to prevent the battery life from terminating due to the low water level. The electro-eye (indicator) is the second line of defense for the safe use of batteries. Users can monitor the use of batteries through the eyes, and maintain the batteries by themselves according to the situation, so as to prolong the service life of batteries. (Batteries are equipped with six taps for water addition)
Because of its high safety performance and superior start-up performance, it is a commonly used product in Japanese OEM automobile factories.
