Hi what is the CCA and Amp hours for batteries for the xj8 thanks?

It seems to be CCA 750 AND 90Amp hours? Is this correct?

These Jags are finicky regarding battery/voltage etc, the recommended battery is a 900CCA.

AGM batteries (absorbed glass mat) are a little more expensive but do have a longer life than regular lead acid batteries, plus they are zero spill.

.

 

And even 900CCA AGM batteries will succumb quickly to a hidden current drain. With no dash warning visible, a new Interstate 900cca AGM drained flat in six months. It was replaced under warranty as faulty but ... the replacement started setting off the security system in 4 weeks, at which point at "drivers door open" message appeared. It seems a faulty microswitch in the latch had been sneakily (until the last couple of weeks when the message appeared) siphoning off enough amps to slowly drain the battery absent a charger/maintainer or driving the heck out of the car. I hadn't been driving it all that much so a solar trickle charger will be my solution, along with a bit more regular use.

I'm with Carnival Kid: get the biggest, baddest, strongest battery you can lay hands on, and pay close attention to it.

 

any H8 battery will do

should last at least 10 years. if you have an active drain figure it out
