battery

Hi, few weeks ago my car showed a message: "battery charge fault", it appears when i have already driven some kilometers and i have to restart the car to this message gets dissapear. I bought a new alternator but the problem persists, my battery was bought one year ago. Could anyone help me?

My 197 has been sat for a while, charged the battery up for 24hrs and now the idles very lumpy And sometimes even shuts off by itself. Won’t rev over 2.5k and misfires sometimes. Electrics seem iffy from what I can tell on the dash as the lights flicker like mad. The power steering is also now...

I was wondering if anyone knew if this would be enough for a 197? Odyssey Extreme Racing 20 Battery - PC545. I've seen people say they use varley 15's with no issue, so I'm sure this would be ok. The car is used for sprints and hillclimbs

I'm having some difficulty removing the two fuse boxes that attach onto the battery casing. They are connected underneath and I don't want to slide them too hard in case of snapping the plastic or breaking the wires. As you need to remove the battery casing to fit a stock air box I would think...
