Anyone Had 12v Issues?

[ninanina]

I’m trying to find out how many people have had issues with their 12v battery

I don’t use my Jazz every day and when I do it’s nearly always for short city journeys

Since I purchased my Jazz about a month ago I’ve had no problems with the 12v system even with this cold snap we’ve been having

One of the reasons I went with the Jazz over the Toyota Yaris was because I knew the Yaris suffers 12v issues; there are many other reasons why I chose the Honda over the Toyota though

I’ve purchased a cigarette socket 12v tester and it indicates 12.2 or above

I also own a Noco GB40 starter pack just in case

Do you have off road parking with power access ?

My Jazz has just 3 years, I have not problems with 12V battery for now. Since I don't use the car every day, I'm starting just this winter recharging the 12V with an external charger (CTEK) sometimes, to prevent an excessive discharge.

Before the Jazz, I had a Toyota Auris, the 12V battery was the same that was on your Yaris. I had problems only after 9 years, during the COVID time, since I used the car too little.
Note that Toyota battery 12V is more reliable generally, it is not with liquid lead. It may last more years, but needs more time to be recharged, so you have to drive for longer time to keep it charged.
The 12V battery used on Jazz is a standard lead battery. It can recharge quicker, but I think that unlikely it may last 10 years...

We have had our Jazz for 3 years and 5 months now. It has never seen a battery charger, booster/jump starter or tester. We often drive relatively short distances.
It always starts without any problems, even if it has been standing still for days. Once it was not driven for 10 weeks and started without any problems.

Mine is just over 2 years old. Used for very short in and out of town trips of around 2-3 miles each way, always from a cold start with a handful of 30-50 miles trips per annum.
The car often sits for days or even a week or two without use. Never had a problem with the battery so far, nor do I really expect to for at least another year or so.
My experience with such treatment, my cars only start to show an occasional charge battery sign when they get towards 4 years old and then an occasional quick charge with a charger extends the battery life.

Unfortunately I don’t so there’s no chance of me using a charger

That’s very reassuring to hear

I am wondering whether you have been worried about comments on this forum? I must admit I have also been apprehensive and my car isnt 2 years old yet.
Remember comments about the 12v battery have only come from a few people out of hundreds.
I don’t expect to have any problems and nor should I . And if I did then to Honda I will go

My Jazz is fitted with a Panasonic 12v battery and I'm confident I won't have any issues even though I do short trips and the car not being used for two or three days a week, fortunately I can give the battery an occasional charge for added peace of mind. I briefly owned a Toyota Yaris Cross which was probably fitted with a Mutlu 12v, a brand that was allegedly causing all the battery issues, some owners were "upgrading" to Yuasa   but the jury is out as to whether this was a solution

What is your total mileage ?

I've only done 4,500 miles in 3 years 4 months so a 12v charge has probably saved mine

[Jazzik]

Almost 25000 km. = 15500 miles.

Thanks

I imagine that if you use your car at least once a week for half an hour minimum that may be enough to keep it healthy

In my case it can be garaged for up to a month at a time as I only do DIY and tip runs and one trip each month just to top up the HV battery

The suggestion was given in COVID time, was to use the car at least one hour a week to keep the 12V charged.
If the battery charge is low, the car can start anyway but the battery may be damaged, on long time, when you keep always a low charge.

Agree with that

Years ago 'she' left the lights on and totally flattened the battery. Even after a 200 mile journey the battery died overnight

I asked my Honda garage about the battery draining quickly. The answer I got was as follows: 'It is normal for a car to use some power when it is idle. A decrease of about 0.5v in a week is not alarming. Your car is started by the electric motor. The computers that control this electric motor generally need about 10v'
