My S is in due for a new battery and I am gonna to use a Red Top Optima. I have read some negative opinions on using this type of battery. I have used these batteries in BMW's & Honda's. 1 of them is going on 7 years and still working great despite being accidentally completely drained about 5 times. Any reason why I shouldn' t use one in my Boxster?
