Thank you Julie, it's nice to say hello to someone 👍

I'm not even convinced about global warning. First we had the ozone layer problem, then that magically fixed itself apparently. Then we had the issue of cutting down too much of the rainforests, citing that the Amazon (forest not website) may provide up to a third of the world's oxygen, then science proved it hardly proves any because the forest is so dense that little oxygen can escape. Then another report claimed 6 out of the top 10 world climate scientists said that it was a natural progression - every few thousand years or so the temperature goes up and down. That's a known fact, and previous fluctuations can't be blamed on the industrial revolution! As for lithium, it's extremely dangerous, extremely toxic and very difficult and expensive to recycle. Currently the powers that be are talking about burying much of the waste. I believe there's a huge man made lithium pool somewhere in South America where most of the world's lithium is produced, mined or whatever and it's said to be the most toxic place on earth. And we've only just started! The cars, well I don't think they've thought it through. Who's going to want to buy a 10 year old hatchback for a couple of grand when they're going to have to spend another 4-5 grand replacing the knackered batteries? What do people do for overnight charging who live in flats and apartments and don't have a dedicated parking space? Half the houses on our street don't have a driveway, What do they do? I could go on of course, but I'm far from convinced that scrapping millions of cars with ICE engines to usher in electric vehicles is the way to go. Surely the place to start is with trucks and buses, and even replacing diesel trains. For me the whole thing is a sales gimmick to help the ailing car industry who are struggling to come up with anything new.

Hi Tim, I am sure There will be members who will need your expertise. Good luck with your new venture. Regards, Julie.

and make sure you connect a slave battery to the positive terminal clamp and the earth to a convenient earth point. You can find plenty of posts about central locking not working after disconnecting a battery. Jaguar issued a TSB. Jaguar solution is to replace the Central and Rear Junction Boxes - not cheap, though it seems that they can be reprogrammed via Autologic. I replaced my batteries a couple of months ago, the stop start was not working, and reset the BMS but no stop start. Then suddenly, the stop start started working last week. A little worrying the first time, thought something had gone wrong when the engine stopped.

Hi You should always replace an AGM with an AGM. They are a very different design to the standard (including Calcium) wet cell. The main difference is their ability to recover from deep discharge which is what you get with stop/start use. In addition the cars charging system is designed for the difference so if you use the wrong sort you may well get a premature failure of the new battery if it is not an AGM. https://batteryuniversity.com/learn/article/absorbent_glass_mat_agm John

Calcium ones are lead acid batteries, with different grids inside instead of lead, AGM seen to be the best at the moment, there gel and dont leak and have better output amp and cranking amps got mine from battery megastore, good value and got it next day, this was before covid though cheers Joe
