I replaced my D4's original OEM battery last year with the Varta G14 and I'm very happy with it. I waited for it to go on special at Autobarn and then got Every Battery to price match it because they provide free installation including diagnostic tool reset (it's simple to install the battery yourself but I didn't have a diagnostic tool so I needed this done for me). It ended up costing $478 and with a 42 month warranty on the Varta you really can't go wrong.
Wow! I’m on my 3rd battery in my 2015 D4 - got 4 yrs out of the original, but only 12 mths out of the 2nd - replaced under its 3 yr warrantee.
Unfortunately, battery discounts for forum members are no longer available. I need a new battery for my L322. The last one, a 60044 (N88HMF?) 880CCA with discount cost $140.
I hit four years last month on my Varta G14 AGM. I’ve put it on a charger for 24 hours at least monthly to try and keep it healthy. The car BMS says it’s down to around 78% capacity, but as of 12 months ago it has a buddy from an SSB secondary battery which has probably helped it live a little longer. So far I’m not seeing any signs of it going off.
I want to place a bet with you. I reckon you:Quote:

If I win the bet and you mainly do short trips and/or leave or come home in the dark, then the battery is trying to cope with heavy loads without the opportunity to be recharged properly. I'm assuming your replacement battery was up to spec. These cars need a very good AGM battery like the Varta G14 or SSB.
Mind you, if I lose the bet, it probably means you're just unlucky and deserve to have a whinge!
I'm sure you know this, but make sure the BMS is reset each time you change batteries.
Haha! Well this is interesting - and I just realised that I lied - its on its 4th battery in 6 yrs!Quote:

#1 battery came with the Disco - bought new in 2015 - lasted 2 yrs
#2 battery supplied by RACQ - I assumed it was up to spec - lasted 2 yrs
#3 battery also supplied by RACQ - lasted 12 mths and then failed big time when 350 km from home, in a very isolated spot after about 1000 km over 2 days. Disco got a truck ride home to the dealer as roadside assist didn't have a spec battery. Dealer diagnosed "dropped cell" - RACQ replaced the battery (#4) under warrantee - no charge.
Disco does short trips around the town (rarely at night) - interspersed with 1000+ km trips every few months. When #3 failed we had done 3,000+ km in the previous couple of days.
I generally tow a 6.5M boat to very remote places on those long trips! Thinking of installing a Disco spec battery in the boat so I have a spare for the Disco if needed.
I have a MY2013 D4. I do all of the above and we only do 10 minute trips to various doctors etc. with occasional 30 minute to 90 minute journeys monthly. OEM battery was replaced last November and hadn't failed but the Indie servicing my car said it was showing signs that it was keeping less voltage so I replaced it before it died. So I got 7 years out of it. Probably just lucky but I think you'll agree it lasted well under the worst possible conditions. :)Quote:

Next step is to replace battery. Manual doesn't go into detail. I will probably hook a secondary battery into 12s plug in rear. Looking at all the positive cabling in front of battery can I slide battery forward to get it out?
No…Quote:

Power up vehicle and using IID tool reset BMS (or it will think it has an old degraded battery in it and shorten its life)
