How to tell if car battery is dying

[stargate]

A friend of mine who owns a CT called me up today to ask how can one tell if the battery is dying. He can't start his car today (at night), and during the day is fine. After a few times starting, the car finally start. He told me there is no sound at all when he turn to "Ignition". THe alarm can be disabled, enabled with no problem.

Any ideas to test the battery is dying? His car is only 6 months old. Which battery is good & price?

1. The starter won't move at all
2. Ur alarm keeps triggering

invest in a volt gauge. get those from autogauge is good enough.

if not, get the maintainence free batts, they last for some time. rm165 can get you a good one. :)

CT can't start, can it because of the start relay not good?

Battery dying, my experience is that the headlight will go brighter and dimmer

touch touch and try to feel the battery at the side whether it's pregnant

anyway i think it's the starter or the ignition problem...
