I need a new battery for my 2020 DB11 V12 AMR any recommendations which one to buy and where from. Thanks.

The dealer is asking around £650 inc fitting. Seems a tad expensive or is it about right?

I've used Tayna Batteries in the past year for both my Aston and Volvo after reading many good reviews on here.

For my Rapide S it was £110 delivered for a Bosch and I fitted it myself.

I believe the battery on your car is under the offside rear seat if you're inclined to do it yourself.

That's where you've saved £500. By not paying someone to disassemble the back seat of a Rapide hehe.

Wow that seems somewhat over the top to me. A wonderful example of Aston tax. I’m not familiar with DB11 but normally changing the battery on any modern Aston Martin involves some trim removal, usually behind the seat, plus a lot of patience and often a lot of swearing! It usually helps if you have hands the size of a small child too. Seriously though, I’d be tempted to take a look on YouTube, buy the correct battery myself and have a go. The only issue you may have is that a visit to your AM MD may be required after successful fitment, as possibly codes, windows, seats etc may have to be reset. That’s more likely the case with Gaydon era cars, but personally I’d try and do it myself as I think £650 is a bit of a pcensoredstake. I may be wrong though, as I expect it is a little time consuming, so it could be worth asking an Indy or maybe Aston Installations to get a price comparison. Good luck. Fingers crossed for you. BRM.

There must be a way to keep 12V during the battery changeover - I saw an AA bloke do it once with a back-up power supply. Hopefully in later Astons settings are stored in a way that doesn't need constant power or AMDS to reset - like the door mirrors...

Good thinking.

Yes it can be done, if you have an available battery. Connect to the 'jump' terminal under the bonnet and the earth to suitable metal.

Best to include a fuse in the secondary supply in case of accidental earthing of the positive battery lead

Greetings Gentlemen,

A couple of things on the DB11 (mine is the V12).

The battery can be disconnected and replaced. You will not have issues with losing presets, coding, etc. The only thing possibly lost (and it depends if the battery is disconnected for enough that capacitance is naturally drained from the modules) is the window presets. These reset pretty easily. I've done it now a number of times.

I have had the battery disconnected in my DB11 for as long as overnight. Only the windows need reset. In fact, just last week I replaced the battery in my car with a new AGM, the change happened quickly enough that window presets were not lost.

If you are still not comfortable, you can supply 12v to the system while the battery is being changed. One way to do that is with certain CTEK mintainers. One of my maintainers (CTEK 7002) has a voltage supply option. It can be easily connected using the CTEK aligator clips directly onto the battery posts, just need to be careful not to accidentally knock them off (especially accidentally touching the + post to ground) during the battery switch. This battery is HEAVY and you will be operating in very tight spaces.

Best of success with it!

Here is my 7002:

In 2023 I had my local AM Dealer monitor the battery in my 2016 DB9 GT to see if it was charging correctly and whether the tracker was misbehaving. It was diagnosed that the battery meeded replacing. The car was monitored over 24 hours and it cost £198 for a replacement battery and £230 for the monitoring and battery fitting.

Got my 2010 MY V8 Vantage battery from Costco, Bosch. It was around £100.

Previously had a Yuasa from Halfords too but it never held a charge very long.

Either way they are easy to fit providing you have a socket and an extension bar to get behind the battery.

AM use Banner batteries as standard others will fit but you need to watch the height of the battery as some are to tall even though they state that they will fit.

I've always shyed away from that just in case I connect it wrong somehow and fry the entire system with 24V!

If you are at home changing the battery then just leave the Ctek/Optimate plugged into the 12v charge port in the boot, most of the optimate/ctek made in the last 10 years support "supply mode" specifically designed for when you changing batteries etc.

Ive changed 2 batteries previously in my Vantage coupe and Roadster, used Bosch silver (delivered next day from Tayna website). I

Need a new one now in my 2016 V12VR. Thankfully its a bit easier on the back changing battery in the Roadster with roof down smile

I replaced the battery on my 2017 Vanquish S recently with a Varta 019AGM as recommended on their website...
Battery located under the rear seat - helps with access that the car is a volante!!
I removed the old battery and took it to the local supplier and returned and fitted the new one (with some choice expletives) without any coding issues or electrical gremlins. Car was disconnected for a few hours...
Knuckles recovering well and the car is fully energised again.

I used the AA (battery replacement service). The chap from their mobile service had replaced one before in an AM (maybe I was lucky?) and the cost was a very reasonable c £280.

Got a local specialist to replace the battery in my 2019 Vantage. Since they’re a specialist and know what they’re doing, they kept the car powered when they changed it over so no mucking about re-coding etc etc. £264 all done.

Another vote for buying from Tayna.

Also note that Bosch and Varta are made in the same factory. You might get an extra year’s guarantee with the Bosch S5, but my personal choice is the Varta.
