I went with Bosch. The previous models had 875cca but the new ones have 850cca. I believe they are 1000ca and have a RC of 75. I bought mine in Nov. of 2007. I just had to replace them under warranty as one of them tested bad and the other was near the end of it's life. I killed em though when my alternator went bad about 5 months ago and again when my FICM died. The price also went up from $69.99 to $99.99 each.
