Question about Bosch Automotive S5 005

Galaxus says that about 4000 visitors are already waiting for my review. Voilà: Delivery very fast. The battery looks like it was pictured in the shop. The voltage is actually 12 V ;-) and the car actually starts ;-) ;-). Amazing! Seriously: how am I supposed to rate a product that I have only just received and whose most important features are reliability and longevity? I'll be able to give a meaningful assessment in a year or two.
