Title: Flat battery !!!!!!!
Post by: Old codger on November 05, 2019, 08:08:18 PM
Hi there....think I might need a bit of help here.....I have a 17 plate 1litre jazz, had it for 12 months, extremely pleased with it so far......this morning went to start car, .....nothing......called green flag, they arrived put a battery charger on it and after a while hey presto we are okay...the green flag man says just short drives does the car no good what with all the gismos on the car  it needs a good 15 minute drive to keep the charge, we took the car to a Honda dealer and he says basically the same re short drives, so his suggestion was put it on a trickle charge once a week to keep it topped up......this does not seem right to me it goes in for its first service next week so I will get the dealer to check the battery, this is the first problem I have had with the car, any ideas or suggestions would be gratefully received......

They are right about short drives, and the bad news is that if your battery is not regularly kept above 80% charge it soon gets damaged and unable to accept a charge.  If you only do low mileage and short drives you will have to supplement the charge that the car provides. The Jazz battery is not the biggest around, but if you make sure you do  few extra miles very time you start the car it should be fine...

Welcome. Car alarm is a constant drain on the battery. If you don't use the car very often, then only use it for a couple of miles, the battery will steadily discharge until the inevitable happens. Ask the dealer to check the battery and the charging system.

Does the car have stop/start. and do you use it?

If so, it shouldn't operate when the battery is low, which gives you a clue as to its condition.

Batteries don't charge very fast these days, so do need run time more than anything else.  15 mins doesn't seem long - we've had a couple of issues with this in the family and the breakdown guys always seem to say the car needs regular 30min runs.

It could be the battery - seems to be lots of early failures of the batteries used by cars with stop/start - not Honda specific, I've seen it on lots of makes, particularly VW group cars.

Well thank you for your replies and advice it is much appreciated.......our annual mileage is about 11000 so it is not as if we do a low mileage but I can certainly keep an eye on the battery in future, again thank you for the response.....

My annual mileage is very similar, and my only experience of a flat battery was in a Mk2 with a 6 year old battery, after I left the interior light on overnight.  Easily done if you decide to look at a map after parking at night, and you don't always notice if you next go back to the car in daylight!

Uhmmm...
Compared with older vehicles, cars with S&S (as GK Jazz) generally have bigger and electronically controlled generators, able to recharge quickier  the battery even at idle. Usually batteries are built with  EFB technology (or AGM), so they can get more current in the first minutes after startup, and state of charge is closely  checked by the energy management system. So I'm not so convinced that short trips are bad for your Jazz. I mean, very very short trips are bad, one, two, three minutes... But 3-4 minutes should be enough for recharge. Maybe I'm wrong, but I'm more worried about forgotting front interior lights on overnight  than short trips.

I love cars who switch off all services after door locking, as my old Renault. Jazz ECU switches off everything but front internal lights...

We have had our Jazz for nearly 4 years and only once had a flat battery - due to my wife leaving an interior light on. The AA guy got it running and told her that 20-30 minutes running on idle on the drive would recharge it. Might be worth checking that your glove box and hatchback light switches are working, doesn't take much to run down a battery overnight.

We have this problem as well, most of our journeys are for the school run and grocery so typically less than 15min drive. I would highly recommend getting a trickle charger and a power bank jump starter - this is a must imo!

With our old car, there has been a few occasions when out power bank jump starter has saved us from being stranded, also helped out a couple of fellow drivers who couldn't get their car started.

We trickle charge our car about once a month now which seems to have worked well for us.

Any particularbmodel recommended? Many cars are driven on cpc  deals so low mileage is essential. Sounds like a catch 22 scenario

I fitted one of these 1 amp AA charger / maintainer for my wifes sister she does not often use the car, and then only short journeys and to make matters worse the car has an alarm fitted so battery is constantly being drained.  Charger comes complete with SAE plug and both a fused permanent connection lead ( with ring tags to fit on battery terminal clamp bolts ) and a lead with crocodile clips.  The fused lead is quite long so poked it out through lower part of front grille, where it can be plugged in without opening bonnet.  The SAE plugs are impossible to plug in the wrong way and very rugged and have a waterproof clip-on cover permanently attached.  It defaults to 12volts charge,  and as long as it is plugged into car battery if you have a power cut at your house it remembers exactly where it was in the charge cycle and resumes when power restored... at end of charge it switches to 'float' mode of about 13.7 volts,  which will keep battery free of sulphation and maximise its life.

they are reduced to £20 now, and they do work well,  we have one for our cars and brother has one for his motorbike

and an extension lead lead to reach up the driveway...

Here is a good article on maximising life of your car battery, it needs to be kept in top 20% of charge..

at all costs you need to avoid sulphation which is cause by keeping a lead acid battery partly charged..

Completely agree with the above. A decent trickle charger is a must in my opinion, I contemplated getting a cheaper one before but having done some research, it seems you do get what you pay for. The cheaper ones do work, but the quality of the internal electronics is not as good.

I went for a CTEK MXS 5.0 a few years ago now, it has been used quite frequently and still remains faultless so I highly recommend them. I'm actually looking to install a socket in the boot of our MK3 to make it even easier to charge frequently.

In terms of power bank jump starters, I have been using one that I bought off AliExpress a few years ago, the main thing for me was to check with the seller what cells they use inside the power bank - making sure they are quality cells (e.g. Samsung, LG, Panasonic/Sanyo etc.).

Through lack of usage my battery is flat. Someone has kindly loaned me a charger but I have no intention of using the car until we can come out of isolation. Is there any point in doing a recharge (from the point of battery health) until I actually want to use the car? In the meantime I have merely disconnected the negative lead. Thanks.

Do not leave a battery in a discharged state - it will destroy it...... lead acid batteries like to be kept over 80% charged or more,  below that the plates sulphate up ( almost certainly irreversible no matter what the makers of expensive battery chargers claim ) and shed active material,  both of which severely degrade the battery - leaving power off the electrics may not be a good idea either.

A deep cycle stop-start battery will tolerate being deeply discharged for short periods but will be far happier if kept in decent state of charge - if you are going to disconnect battery anyway why not remove it and keep it on charger off the vehicle in the house or garage.  If you want to leave charger connected make sure it has a 'maintain' function where after main charging it can switch over to a 'float' charge,  normally a light changes from amber or red to green on charger when it is happy and is in maintain mode.

There's a lot of it about just now. I tried to give a neighbour a jump start yesterday. Turns out the battery in his 12 plate Mercedes A class is under the driver's seat which, unluckily, was against the pavement. Just couldn't  get close enough. He got going with one of those Lion packs. Our street has set up a great Whatsapp help group.

I'll pass on the tip about keeping it fully charged but at 8 years if it's the original battery I suppose that's to be expected.

Hi There,
Left car standing for 3 weeks then took it for drive, 2 days later moved car to work in on garage doors had not closed car drivers door properly. So interior light left on went to start in the evening flat battery. Have been looking at new battery last year as this is 2014 car, but the battery is not original it is a Varta 35ah 290a so this battery is at least 3 years old. looked at Yuasa ybv5054 as this the honda original. Had a look on ebay and other sites selling for about £50.

Good point,  you need to check handbook if you car has idle stop.

idle stop-start needs a flooded or AGM deep cycle battery.

Good point,  you need to check handbook if you car has idle stop.

idle stop-start needs a flooded or AGM deep cycle battery.
2015 Jazz has idle stop-start, the OEM model is an EFB Yuasa YBX7053.
Similar EFB models can fit, as following:

Banner 55515
Varta Silver Dynamic EFB N-55/80B24L
Bosch ST Hightec EFB 70B24L (N55L)

Other models can be found in Japan, but here we can only have Yuasa, Banner and maybe Bosch and Varta (I found these last two only in asean online shops).
AGM would be better for carging cycles, but AGM batteries (as Optimas) must be recharged under 50°C, and I don't know if the engine bay of our Jazz can keep this temperature and if the charging system can inhibit deep recharge if the battery temperature is higher.  Many BMWs have the AGM battery inside the trunk, this is for weight balancing but also for keeping the battery fresher. Also many toyota hybrids have a small AGM battery for 12V services placed in the boot.
I presume that our Jazz has been built for EFBs, so if temperature check will be done during recharging, it will be set for EFBs, not for AGMs.
Last but not least, in a 2015 Jazz with stop&start standard batteries should not be used  at all, even if the user will disable the S&S at every start: the recharging system will send to the battery an higher amount of current, good for an EFB  but too high for a standard battery, so a cheaper battery will last much less even if the S&S will be disabled by the user.

Just had a look under the bonnet on my 19 plate EX, which has idle stop/start and the wording on the battery is rather different,  to what has been listed by other members.

It is  GSYUASA B24 (JIS) 12v (made in Japan) 50AH. 490CCA,

This seems to be a much larger battery, than what I remember on previous Jazz’s I’ve owned,

i checked mine yesterday, i have the same battery and it was at 12.54v so i took it for a run to get it back to 12.85v but it always starts instantly even after a week or two, must be the more powerful agm battery style


im more concerned about the a/c compressor when you first turn it on after a week or so it makes a bigger click noise than its usual on off noise, it works ok and its just on the first switch on after a week or so, so must be normal

Yep, I have to update my infos.
According to user manuals , it looks like manual gearbox Jazz have different batteries from CVTs, and the MY19 have bigger batteries than earlier model years. My19 have N65 size batteries, earlier my have a smaller (and harder to find) N55.
My battery is slowly dying, according from the instrument panel. 3 Years, 37000 miles, the idle stop start does not work anymore even after an overnight recharge (following the technical paper). The cold startup is still good, but I will buy a spare Yuasa or a Banner for the next winter.

Hi All, Just my battery delivered so 2 to 3 days after ordering great going in these times. Very well packaged and sealed from any leakage, took red seal caps off either sides. will trickle charge up weekend lots of work around and inside house. Stay safe Keep well
