Battery Poll!

Seems to be a lot of bad batteries which makes me want to slowly back away before getting in too deep. Completely unscientific, but it would be nice to compile some data in one place. Doesn't look like this forum can do a proper embedded poll, so I'll ask for an old-fashioned reply post and...

Just a thought but having the 12v batteries continually being refreshed by the main traction battery would open the vehicle up to damaging drain on the main traction battery - which would be much more expensive and serious from a safety perspective. Much easier to switch out a small 12v battery than the main battery pack.

 

Re: the idea that modern 12v batteries are inferior to old ones. When was the last time you had to open up your 12V battery to test the electrolyte or refill it, or had it explode or leak? Modern cars are definitely harder on their 12V batteries than older cars with all of the additional electrical load put on them, but the batteries themselves are undeniably better than what was available not too far in the past.

I don't point this out as a criticism, but more to suggest that positive changes often go unappreciated when they allow us to think less often about something. We don't have to pay attention to automotive 12v batteries the way we used to, which makes the problems we do have with them seem more onerous when in reality the opposite is true.

Don't get me wrong. I was really thinking back just a few years. If I look at my batteries in the 1996-2008 range, I don't remember ever having to change a sealed battery before 4+ years, but after that it seems like none of my batteries would even make it three years in my ICE cars. I went through quite a few used cars back then and still hardly ever needed to change out batteries. I was really satisfied with the early Diehard sealed batteries. Am I just remembering wrong or did we have better sealed batteries just 10-20 years ago??? My colleagues at work seemed to agree with me or they might have just been nodding their heads... I don't even think the warranties on batteries at AutoZone, Advanced, and other retail parts stores are as long as they used to be.

 

I had some issue with the 12v last summer, that triggered some weird messages on the dash. Hopefully it was always on my driveway, and I was able to fill up manually the 12v to clear the message. When I told that to the dealer, they have upgraded the BMS and the gateway module. Since then, no issue at all.

 

I agree with you, jamminhammin. The battery in my RR didn't make it to the end of the warranty (4 years/50K miles) and had to be replaced. I actually let it go for about 10 months until just before the warranty ran out. The sign of weakness was the stop/start feature had stopped working. It's an H8 AGM battery. I've had to replace batteries in my other ICE vehicles about every 3 years too.

The irritating part of the I-PACE 12V batteries is the special sizes. They might be easy to get in the UK, but you won't readily find them in the US except at a JLR dealer. We'll all need replacements someday.

 

I get my first problem Today, the tower jump start the battery just to get the car tow to the Dealer. Do not know what the problem yet?

 

So...... When to swap out the 12v battery???
I have a 2019 HSE. Have owned the car for 2 1/2 years. Should I just replace the 12v battery now? Or wait for a problem? Or a failure of the car to drive?

Or how do I know when it's time?

Thanks for any advice.

 

My 12v battery was replaced 2 days ago. For more details, please see

Had my First Edition for almost 2 years and 30,000 trouble free miles now but yesterday, for the first time, "OK to drive with caution Break pedal feel reduced" appeared in the left side of the dashboard display. At the time, I thought maybe the charge was too low (only 7% charge left) as the...

All of us will eventually need to deal with and replace those 12v batteries. In my case, this Forum has helped me getting through the incident without much trouble but many has reported otherwise. If we are prepared and kind of know what to expect, then it should be ok to wait until warnings show up. I do not think the Jaguar will cover it without at least seeing the warning first. Search this forum to see recommendations on having a 12V battery charger in the vehicle as well as install accesses cables just in case.

 

Had a 12V battery issue. When to Walmart and bought a $60 battery and connected it via jumper cables to the battery under the hood. Enabled me to drive to the dealer. Battery was replaced at the dealer the next day, and they kept it another day to test a charging cycle as a precaution. Returned the battery to Walmart when I got it back.

Saved a lot of inconvenience with a tow, I think.. maybe this was just as much effort, Hmmm..

 

Does anyone have any input as to what battery to buy to replace the original 12V, if you don't want to go the JLR route? What is the right fit? a size 48? 49? thanks!

 

Starter battery is a 99R/T4 or UK battery 063 size. You can find it auto part stores.

Auxiliary battery in pre MY21 is an Exide EK151. You won't find this in any part store or battery shop in the US. Sources are JLR dealer for JLR battery or European sources selling on Ebay.

Thank you! Much appreciated

 

There are plenty of batteries out there that are the correct amps. The problem is they are not bolt on friendly to match up to the I-Pace connector posts heights, the body widths and length. There is a Lithium iron phosphate battery that I am considering installing in place of our current starter battery when my warranty is up, or they tell me my car will be waiting for weeks for a new one from Jaguar. I already have the brass post adapters to make the LIP battery fit and the battery is physically smaller than our current lead acid battery is. (It just took my dealer 3 days to get me a new Jag starter battery.)

I located the regular sized brass adapter posts for my postless AGM Start battery conversion.

I also searched online for the smaller diameter terminal posts to suit a postless replacement Aux Battery, but I failed to locate any.

Have you found suitable adapter posts to suit a postless replacement Aux Battery? Could you post a Link if you did?

Cheers, Steve

 

Aluminum rod with a little taper filing and a hole drilled into the end for a bolt to screw into the battery connector cage?

 

Just had this happen to me last week - car is 2.5 years old, couldn't stay started, had a Battery Traction Fault message, then a few others - no indication of what the problem might be. Jaguar service wasn't helpful on the phone "just get it to the shop".

I have Jaguar Roadside Assistance, and it took 1.5 days (yes DAYS) to get a tow truck to me, luckily the car was at my residence. Since I had not run into this before I was worried how they would get the car out of my garage - I live on a sharp incline and the width of my single car garage is barely enough (1-2 inch clearance on either side view mirrors). I kept going out to the car and starting it hoping it would stay on. Once out of 50 tries it would let me change it to Drive or Reverse, but it wouldn't go anywhere and the indicators would just flash. Finally after a few hours, it let me put it in Reverse and slowly got it out of the garage, but still not in a good position to have it towed. It took another few hours for it to finally get into Drive and I could move it in front of the house. Luckily, I didn't have the problem others have had with the frunk not being able to be opened. Once the tow truck driver came, he attached a portable 12v battery to mine, and it started right up! The car was in the shop for a full week - 3 days for the battery to arrive then 2 days to install/test (this spanned a weekend too). Apparently these batteries can't just be sourced from AutoZone...

I've now purchased a 12v portable battery similar to this and will keep it charged and in my trunk for the rest of my ownership.

Most recently I had been making 65 mile long trips and this would have really screwed me if it died that far from home. I'm considering ICE again because of the Jaguar Assistance and Service shop experience.

 

It appears you had a failure of the aux battery. Please correct me if I am wrong. I had a failure with the starter battery and used a 220CCA rated lithium iron battery to drive the car around for a week waiting on the lead acid stock battery, without any problems(no hvac, radio, seat heaters used). But when the aux battery failed also, it appeared that it drew more amps than the starter battery did and required me to jump the car with my wifes X5. The battery you have a shortcut to does not appear to be rated in the standard CCC (ColdCrankingAmps for a time) for any car battery, so you have no idea as to what you are really getting.
