Replacement battery- 2007 V8 Vantage

[NickXX]

Hi all,

The time has come I think. My battery no longer takes a trickle from my Aston/Ctek charger and struggles to last more than about a week, so it needs replacing.

I'd like to get an upgraded battery if such a thing exists (possibly an AGM one?), but the thing that matters most to me is that it fits perfectly in the cradle- so am a bit worried about deviating from OEM.

Has anyone replaced their battery with an 'upgraded' model. If not- where is best to get an OEM battery from, and what sort of price should I be expecting?

Thanks,
Nick

They're a pretty universal size based on the specs. You can get them from Halfords, ECP etc.

I recently got a Yuasa from Halfords. It's slightly up on capacity and cranking power over the OE battery and a perfect fit.

There are a number of direct replacements, but "upgrade" is somewhat relative - depends on what your aim is. I've got a small AGM battery in my car with a mounting bracket to fit in the factory location. This setup drops 13.5 kg of weight out of the car. Also makes battery swaps a 5-minute job. I consider it an upgrade because of the weight savings.

Is the battery you refer too in An Aston? If yes which battery is it?

Thanks Steve

Ah, thanks guys. I'll probably go for a Yuasa if it fits well (got one in my M3 and seems to hold charge for 6+ weeks).

By upgrade- I'm after something which doesn't get as upset as the OEM one when the battery drops below 75% charge.

Everything is relative. If you are wanting a true upgrade (better CCA, better useable Ah, save more than 15 kg, longer life) you will be after one of these.

Amazing lightweight battery and what I would like to put in my V8V

or if you want even more CCA and Ah but 3kg heavier.

Still an amazing battery with more reserve and excess

When you look at the price, you might want to go and upgrade your wallet to.

Yep, the battery mount is sold from Redpants (full disclosure, it's my company and my rouge pantaloons), and the battery is a Braille B3121. The mount is shaped to match the base of the OEM battery so it fits in the original spot with the original hardware. If you do a Google search for "Aston Martin V8 Vantage Lightweight Battery Kit" you should see a couple videos I made about V8V batteries as well as my website in the top results.

Thanks Telum, looks interesting, is it a lead acid battery, or not?

Thanks Steve

I put in a Varta Silver Dynamic AGM G14 when my Vantage battery died. https://www.batterymegastore.co.uk/products-by-man...

Thanks Steve

Braille batteries are AGM. I'm a huge fan of AGM over lead acid batteries. My Braille has been great so far, and I've also been really happy with Odyssey AGM batteries that I've used in other cars in the past.

Cheers Steve, I've sorted it out now, I was sure I checked when I did it.

Thanks drac, brilliant stuff, but restrict fully expensive, shame that. I might of considered up to £300 for a battery, but not a £1000 plus.

Hopefully prices will drop as they become more popular.

Thanks

Quick update to this - I've managed to get the battery charging with the CTEK. The rear lighter socket doesn't let it charge for some reason, but the front one does. Battery seems healthy and charging properly now!

It would be worth getting the 12v socket in the boot checked - my 2007 car allowed this.

I originally looked into lithium batteries, but the cost!!

Braille B3121 with mount is 530 USD and drops 29.5 lbs, so $18 per lb of weight loss
Braille i49CE (lithium) is 2050 USD and drops ~39 lbs, so $52 per lb of weight loss

Looking at it only from a weightloss perspective, the lithium battery is nearly 3x as expensive. That doesn't take into account not needing to replace the mount when replacing the battery, which drops the cost to a little over $8 per lb of weight loss (1/6th the cost per pound compared to replacing the lithium battery).

So yeah, I went with the AGM battery over the lithium one!

Take a look at the battery in the car, It should already be an AGM battery as it's sitting behind the back seats (lead acid batteries can vent and therefore kept for use under the bonnet). It should have a group number on it (like H6 or Group 65). Order a battery with the same group and be done with it.

Different batteries have different charging characteristics so if you have an AGM battery , it would probably be smart to stick to what you have. I know that on my Mercedes, you need to use a scanner to go into a special menu to change batteries if you switch from one to another.
