Hello Steffen,  
I am trying to find the manufacturing date for the Battery BAT412201104, there are no further informations on the battery. The reason is that I have to decide to replace the 2 batteries on my boat. They are showing sufficient voltage, but loose charge rapidly when a load is applied.
