Previous owner installed a Bosch from pep girls before I bought the X 2 years ago, cca of 850 I believe? Anyway the X hasn't had a hiccup since then, if JCL or quicksilver post up here the battery brand chart you will notice that 2 manufacturers (Johnson controls and exide I think?) make all the replacements found in stores, so you really can't go wrong as long as you buy the right type.
