New batery for Mercedes 500SL

another on the rear trunk. I have replaced the one on the back but now the one in the engine compartment is finished. Dealer wants $270 can $ for that small battery . It is much smaller that the other one. More like a motorcycle battery. Must I payed that much for a small battery only because is made in Germany?
