I need to replace that battery in my dads 2010 TDV8, before I just order an AGM 019 battery from Tayna I thought I’d check into see if anyone has any recommend brands or other options for a replacement battery on a 2010 TDV8.

Try the Battery Group in Yorkshire, that's where I bought mine.

I got a YUASA 019 from Halfords (I know) £103 with trade card, £158 without Dec 2021- 2010 Facelift TDV8 4.4 AB in Stornoway Grey.

It’s had a non AGM Yussa in it for. While and after poor experiences with Yussa on another car in my fleet not going like for like with this one.

To answer my lown question I looked the part number for the battery on the Jaguar Land Rover classic parts site which points at an Exide EK820 which is an AGM 82AH 800A battery, but the EK960 which has the same physical size as an 019 but is 95AH 850A so I’ve ordered one of these from Tanya.
