AM vantage roadster 07 battery dies after 2 days trickle

[DRK007]

My AM vantage 2007 roadster trickle charged for 2 days, then removed , starts perfectly. Drove it around that day for 1 hour. Then parked the car up at home and did not drive for 2 days, now today car is not starting at all. I've stuck the trickle charger again. This has been going on for 2 months. Can anyone explain please? Is it a dead battery or something major? My warranty has finished to and not renewed

You need a new battery, almost certainly this will cure it.

You can do it yourself, the Varta one is about 140. Or pay 180 and get a dealer to do it, they will also reset all the check lights that will come on too, already the windows and seats etc.

Oh ok thanks. If the battery change doesn't work what else could it be?

Take it to a dealer. They will charge your battery up to maximum and then measure the current drain overnight. If it is excessive they can find the cause and it may save you getting a new battery. If there is no abnormally high drain but the battery has lost a lot of charge then you will know it is the battery.

It will almost certainly be the battery...... Unlike batteries of olden days, that seemed to struggle on for months and then fail, modern batteries lose a cell, and fail almost instantly and almost completely...

Modern cars are stuffed full of electronics, once a battery starts to lose capacity, the electronics will kill it pretty quickly..

Exactly (if its still under warranty)
Both my roadsters did this to me
1st was eventually traced (using the above) to a faulty wiring loom on the drivers seat battery survived multiple drainings
2nd was traced to a 3 month old battery that suddenly lost 2 cells so could only hold 8 volts

Cheapest thing first. In all probablity Yeti is right the battery is faulty, change battery. However V8Wollie is also right, if something is draining that should not be ... then that is the problem.

Cheapest thing first, take it to any reputable car spare or tyre/battery shop/store and they will put a resistor accross the battery (if they can find the damn thing - as they won't know where it is). The resistor will drain/test the battery and they can tell you if the battery will hold a charge. This should be free of charge (no pun intended)

But like I said cheapest first, if your car is under warranty, take it to AM. If its not an AM warranty (and anything like my warranty) it wont be covered anyway, as its a service item.

Thanks guys.

I'm attempting to remove my battery first, but stalled when it came to remove the plastic strap that wraps the battery round. I think there's a screw but not sure where it is. Can anyone help me please?

I'm ordering a battery online the specifications for my current battery is 12V 90AH 680 amps. I've found a Varta battery online 12V 95ah but doesn't say the amps. There's an alphaline 12V 100ah SAE 800. Which should I chose?

Many thabks

I havn't really looked into battery technology or the ones that we need, but I am told that because the battery is internal, it should be a, "gel", type and not a water type. Something to do with being inside the cabin. If the car is in an accident and ends up dripping acid on you, "it not being a good thing", so they put Gel in them, to stop this happening.

Is what I have been told about Gel correct, could someone advise .......?

[DRK007]

The battery ive been looking at are 'sealed calcium'. Is that ok for my vehicle where the battery is situated behind the seat?

If you can possibly buy a Yuasa battery that fits do so they are brilliant . My number two vehicle is a Toyota Hilux! she is now 10 years old and still on original Yuasa Batteries which show no signs whatsoever of deterioration. Interestingly enough most new motorcyles are fitted with Yuasa batteries and they have to cope with very high compression. In my opinion it is little short of disgrace that manufacturers chose to fit sub standard batteries

Yuasa are good batteries Rob, we have used them for several years. However, of late their warranty procedure is pants. So we now use Varta - who definately are NOT sub standard. Equal to if not better than Yuasa IMHO of course.

Tony as you well know I have been languishing in retirement for many years now, as a consequence I am a little out of touch. So I guess in about another 5 months when Purdey is 2 years old I shall be seeking out A Varta Battery.

Guys sorry to interrupt your loving conversation but can someone help me and tell me how to remove my car battery from my vantage roadster 2007. It's located behind the drivers seat and I've almost dismantle what's needed to remove
The battery apart from one part- the 2 metal plates that's slide across the base of the battery. They have screws on them which I've remove but they don't slide off because it's too tight in the region Im working in. What am I doing wrong?

I don't want the car to stay battery- less for too long.

Thanks
