AGM without a doubt

Does it matter if my old one isn't AGM ?, ie do I need to do a like for like swap,or doesn't it matter ?

Ive only had good experiences with AGM

However I have an OEM battery (VARTA) and its a 12v 90ah 850A AGM which suggests its a bit weak for a MY2010 fatty? Pinged an email to the local Indy and got a supply and fit quote of 295.00 which seems steep (or not?). Need to check exactly what they will be supplying.

Is it likely I will have to change settings if I go for an AGM one then ?

AGM have a higher charge voltage than a normal battery.... BUT, they are more expensive than a normal battery, they only carry a maximum warranty of 3 years, and they have a smaller capacity than the 020

If your car has an AGM as standard then you'll have to stay with them, but if your car is an older ffrr (I don't think that AGM was fitted before 2010) then fitting an 020 will give you better bang for your buck.... and out of those that are available I would go for a Varta 020 silver, can be brought for just over £110 delivered and has a 5 year warranty.... plus Varta batteries were used by Land Rover, so your fitting OEM / Genuine just with out the Land Rover badge and the £100 markup

Thanks Miggit, that explains a lot 👍

I'm not with mine today so can't check but it's a 2008 so presume not an AGM,

Is the Varta 020 silver an AGM battery ?

No the Varta 020 is a lead acid battery and has a 5 year warranty, the AGM version is an H15 and only carries a 3 year warranty, plus it's 105 amp hour instead of the 110 Ah that the 020 is  Yesterday I couldn't spell Engineer... Today I are one!

The original battery fitted to my 2010 (2011MY) 5.0sc was also a Varta - 90Ah 800 Amps

The petrol engined cars had a smaller battery fitted, an 019, but the larger 020 will fit... they are the same height and width, but the 020 is about an inch longer  Yesterday I couldn't spell Engineer... Today I are one!

Got to go get a new battery tomorrow ,

Been reading all the battery posts but just can't decide between ...

A Varta Silver

Or

An AGM Battery


What would you do ?

AGM.
Your motor is around 6-12 months older than ours. Ours was fitted with a standard flooded cell battery, I changed to an AGM, didn't alter any software (don't know if it is possible on pre 2010 motors).
Charge voltage went up from 14.3 volts after a start up to 14.7 volts, this taking into account that an AGM usually needs a higher charge voltage.
Motor has been fine ever since (fitted for a year now).
Quite a few others on here are going down the AGM route and seemingly not regretting it.

AGM batteries are primarily leisure batteries designed for deep discharge.. basically they are for stop / start eco cars as they have a high duty cycle. Unless your doing lots of short journeys with the occasional long run there is no real advantage to an AGM.. they were fitted to later cars because of the remote FBH feature. They require the higher voltage for charging so that they recover more quickly, after a certain level has been reached they charging circuit reverts to the lower 14.1 volts to finish the recharge off.

While an AGM will work on a normal system OK, you wont be getting any of the benefits of the technology as the charging circuit isn't designed to charge at different rates. So fitting an AGM will give you a battery that is 50% more expensive, with a lower capacity than a normal battery and will come with a warranty that is 3/5 ths shorter than a std battery...
So if you want to pay more for less that will run out quicker, go ahead But it really doesn't compute....

Get the 020 Varta and You'll have the largest battery that will fit without hassle, and give you the largest capacity available with the longest warranty.... My battery was a Varta and the car was 13 years old when I changed it, while I don't for one moment think it was the factory fit battery, I believe it was the second battery the car has seen, so it would be fair to assume that they managed to go for 6.5 years each before they gave up

If Varta give a 5 year warranty, so you can bet they have tested them well beyond... they aren't in the business of giving them away  Yesterday I couldn't spell Engineer... Today I are one!
