2020 Nissan Sentra battery
 

I just had to replace my battery. Can anyone tell me why it is so expensive? The battery was 310.00. I was told it was a specialty battery by the parts person. The mechanic didn't know. And the girl who helped me said something about some gel inside. I was floored it was so expensive. Just wondering why. Thanks in advance.

The shortage of battery raw materials last year caused many suppliers to raise battery prices
