...Just how long would you expect one to last?

Dropped the other half off at the hair dressers this evening. Went off to the local supermarket to pick up a few odds and sods and then back to the hair dressers.......................waited another hour :rant: Spied her coming out, went to start the car and................absolutely nothing :eek: the battery was as flat as a pancake :eek:
The battery is four years old, but has done 92000 motor way miles.

I'd have thought 4 years was pretty average age for a battery to need replaced.

Check it's charging properly (quick test it to start the engine, let it idle, and switch on some heavy-duty electrics - main beam or rear demist - and see if the revs drop slightly).

If the battery's on it's last legs, the cold(er) weather will be aggravating the situation.

The 147's battery lasted almost five years. Had it changed after noticing lazy starts.

I think you've forgotten to tell us what electrics you had on while waiting outside the hairdressers..
If headlights, not more than 5minutes.. if radio, depends how loud.
If heater and fan.. again depends.

4 years and you are on borrowed time. They can last longer, or shorter but 4 years plus is usual.

4-years is about average for battery life.

Agreed.
I understand another sign of a failing battery on an Alfa is erratic display of dashboard warning/ failure lights, happened to a mates 147 after less than 4 years. Although it started perfectly well, a change of battery cured the problems

Radio was on low, fan, again low. Car started first time with jump leads from my daughters Fiesta. Bit of a bugger to get the positive lead on though. It's started first time since as well with no problems but with the winter here i know I'm on borrowed time with it. Any recommendations for the replacement.

cheers all,

Todd.

Like Todd, I'm going to have to replace the battery soon ... sluggish on cold mornings even in the garage!! It's at least 4 years old, so I've got my money's worth (original lasted 6 years!).

The current battery is rated at 550amp/hr and hasn't been a problem, but wondering if I should look for same or a higher spec. Car is manual and doesn't have any fancy audio system, just a multi-CD stack with original radio, etc.

i was doing the seats at the weekend with radio on and noticed sluggish start on monday morning...I guess 6 years is good going for a batt these days.

*vw batt died in my brothers car after 4 years, without warning I hasten to add. was more like a complete ECU failure

Newbie question here ...

Mine has the original battery so I suspect that at 5 years and heading into winter its time I thought about swapping in a new one before im parked somewhere with a dead car in the rain some night .I understand jump starts are a real bad idea on these.

What effect on the electronics will removing and replacing the battery have ? Will some sort of reset be needed or does it all just relearn all over again .. also the radio code , do I need it before disconnecting ?

You will need the radio code if it has one. If it isn't in the handbook pack, you'll have to get your dealer to get it for you usually.

The only thing that will go is usually the trip meter. But if you leave the battery off for an extended period, I've read here the ECU can lose some settings and it goes through a relearning process. Never seen it on mine .. I reset mine through my AlfaDiag package.

I had to change mine last week. Given it was the original and has provided 103K's worth of service over more than six years I guess I can't complain. My local non-franchise Alfa specialist fitted a replcement for £60.

My 147 JTD wouldn't start this morning! I've had it since Friday) I went to Halfords expecting the battery to be dead but they checked it and it turned out to be OK, they then checked and tightened up the connectors and all was well (so far). Might be worth a check, 10 mm spanner needed.
They warned me that the connectors were 'wearing away' (electrolysis anyone?) would only just tighten up and might be a problem again.

Not that I'm bitter about it but...I got a "glow plug" error and failed start last saturday. I got a jump start and took it to Alfa...total cost of new battery and fitting - £180. I'd have gone nowhere near the dealership if I'd known it was just the battery (only 58k miles, 2 years). Still live and learn.
