Battery on my 08 C4S is now 6 years old. Working fine. Use a maintainer when gone more than a week.
What are signs of imminent failure? How long can I expect to go before replacement? Don't want sudden failure as described in this forum. Thanks.

Once it starts giving you the cold shoulder for no reason, that'll be the sign you're looking for

Top up each cell with distilled water and let it go another year. Wear eye protection and rubber gloves.

The other indicator of a failing battery is lessened capacity, and a failure to hold a charge (made worse by parasitic draw from the keyless entry and security systems). This is pretty easy to test with a voltmeter- if your battery voltage keeps dipping below 12.5V after sitting just a night or two, it's on the way out; replace it. If the voltage drops too low, you'll find your car hard to start. If you notice your car is a little hesitant to start, or has to crank a little longer than normal? That's the warning sign you're looking for. Considering how much harder it is to replace these batteries after they die (what with needing battery power to unlock and open the frunk), it's best not to wait that long. 6 years is a good time to just replace it preventatively.

You'll notice being out of breath, when your push starting the car.
Took me few push starts. Then I started parking on a hill.
When in doubt, just put a new battery in. Cheap.

Modern cars give little warning that the battery is getting weak. My car is also a 2008 and I am considering replacement the battery this summer. I keep it on a maintainer all winter but I did notice a few times this past summer ( it is a weekend driver) that when starting up, it was checking the PSM. I think this might be a sign of a weakening battery?
