12v battery

My Kona 64kwh called the emergency services the other day. The next day the microphone for handsfree and voice control stopped working. I researched, to find that both these things have been signs of an impending auxiliary battery failure. In most cases the owners either gave it a quick jump...

Some of the points in this video apply to other EVs so here you go 😎… Although it is a great car the Kia Niro EV (e-Niro in Europe) is not perfect, like any car on the market. In this video I list the things I “hate” about my Niro EV, now that I have owned it for almost 2 years and over 36,000km...

Hi, Apologies if repeated or noob question! I'm planning on buying the new Zoe later in the year. I currently have an old diesel yaris and regularly use is to run electrical equipment via an oscillator. Can happily draw 2kw from it for a little while with engine off, if more then 10mins I run...

Jumped in the van today and warning lights on the dash. Everything was tickety-boo last night when I left so no reason to suspect such behaviour. Pulled the 12V battery out and have it on trickle charge overnight, hopefully this is the culprit as it looks as if it has never been changed in 3...

Title says it all really; can the 12v battery be trickle charged whilst connected to the car? Bought a new battery for friends ICE car this morning, tested the voltage to make sure it hadn't drained in storage before being sold. Then thought to test the Volt's 12v battery as been meaning to...

Hi Guys, As I said in my Icebreaker post, I've just installed a dashcam/reversing camera in a Zoe R90. At the moment it is plugged in to the cigarette lighter, but this cuts power shortly after exiting the car (as it should). The dash cam manufacturer (Auto-vox) makes a fuse tap kit to...

Hi guys, I need your help, last night I got an error message in my GTE: "not charging 12v Battery". This morning the error has disappeared but the OBD gives me a red fault code: P0D57 Drivetrain fault. I can't find more about this than "Proximity Detection Circuit Range/Performance". Any...

Had to get rescured last night, came back to find dreaded 'service steering lock' message, so fixed that by pulling and replacing F2, then got 'service 12v battery' message and all sorts of alarms and flashing displays. When the recovery guy arrived put his 12v jumper pack onto the jump start...

Hi All, Had a bit of a scare a few days ago. I started the climate control remotely to defrost my car, left it going for about 12 minutes and actually heard it shut off on its own as I got in. When I started the car it said it was in neutral (I left it in park) it also had the 12v battery...

Just returned from 2 weeks holiday in Spain (Costa Blanca) and thought I would bore you all with a few observations. Firstly there are no public chargers in that corner of Spain. Consequently, there are very few EVs. In 2 weeks I saw in total; an e-NV200 utility van, a BMW i3 (rex unknown) and...

I have front and rear dash cams i want to remove from my old car and put in the Rex. Am i right to think that these can be wired in to the normal 12V car battery system without needing any special BMW service expertise? I ran a portable air compressor from the car's ordinary 12V battery a few...
