Flat battery !!!!!!!
« 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...
Some people will only consider you an expert if they agree with your point of view or advice,  when you give them advice they don't like they consider you an idiot

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.
