12v battery maintenance, issues, etc.

Wow… this thread was a hell of a read!

I have bought an gooloo jump start kit that I keep in car should the low Battery happen, but wondered are these any good?

Or just a waste of time and not accurate enough? 
 

Thanks

I use one in my Yaris Cross and it's excellent.

I start up in accessory mode and it immediately shows the Battery voltage 12.3-12.6 volts

When I change to ready mode to move off it then shows the charging voltage 14.4 volts.

As I drive along the voltage switches between 14.4 volts and 13 volts depending upon the state of charge.

When I get home, park and shut the car down it switches off. 

Does the job perfectly and well worth the money.

Thank you 🙂

Hopefully it will give me an indication of whether I’m heading towards low Battery issues then

Bare in mind that it shows the voltage but not the capacity of the Battery but at least it's a starting point.

Someone posting on here  used the excellent analogy of 2  glasses which appear full of water but one is half filled with sand ie they are both full but but one is actually 50%usable capacity.

Ahhh right, got you

Do you know if the bluetooth ones show the capacity or just the voltage same as these? 
 

For £7 tho, I’ll get one of these anyway 

[DamoGR]

Bought that for £7 and also a CTEK charger

Question for anyone who has one, do you charge it with the bonnet up, or you prefer the boot Battery?

And if so, do you make use of the permanent attachment with the convenience plug?

Just wondering what I’m best off doing that’s all 

Thanks

The bluetooth one only shows the voltage.

I would use the  convenience leads and  leave permanently attached to the Battery rather than keep lifting the bonnet. You could get the ctek extension leads and run into rear  passenger footwell so you can plug in and shut the door. The seals are very thick on my yaris cross so don't pinch the cable. Check that yours are the same.

That’s awesome thank you 🙌

I did think how am I going to close the car up as my cable would have to go through the boot (as the Battery is in the back)

I only wish I’d got a garage like you, as I have to think how I can do it when it’s parked on the road 😩

Use to charge on a private road via the door seal but always felt open to someone triping over wire so moved to solar charging.

Looks good, but pricey tho

Not as concerned about the cable to car, but more about how I can leave the car unattended but charging 

I don’t know if there is a way of leaving it locked but cable inside

@DamoGR If you bring the cable out between the bottom of the door and the cill you can shut and lock the car........or am I missing something.

I can certainly close and lock my Yaris Cross with the Battery charging.

Photo 1. Charger on toolbox and cable going across floor to the back of the car.

 

Photo 2. Cable going into the car between the bottom of the back door and the cill. My Battery is under the seat. I understand your Battery is in the hatch so get the longer ctek cables and route the cable under the back seat.

The door seals on my YC are so big and soft the cable doesn't get pinched when I close the door. The car is locked.

[Derek.w]

You can bring cable out via passengers rear door thats not a problem close door and lock the car for mains or even a solar panel thats is attached to your garage.

I use to push the plug and mains socket under the car in case it rains that mains charging on a road and across a footpath not to mention going down steps at side of footpath.

All my solar panels are inside the car so a lot safer and I deploy them in car parks.

@Chas G @Derek.w Thank you so much for the replies, really appreciate it

I will try the cable through the rear door sill, and hope that it doesn’t create a pinch point
