Battery: Application and ID

As of 1.1.97 a battery with felt has been installed in the models specified above for a limited time. This battery is hermetically sealed. i.e. neither gas nor electrolytic fluid can escape. The gases produced in the battery are converted inside the battery (retransformed).
A 62 Ah 400 A battery with felt is used instead of the previous 75 Ah 400 A battery because the battery with felt has significantly lower capacity losses due to the new design.

These batteries are marked with a rating plate and should never be opened.
They differ from conventional batteries as follows:
a. No plugs
b. No acid level marks
c. No exterior vent
d. Rating plate on battery
