Auris Stop/Start battery

[jonny123456]

We have a 2009 plate 1.33 Auris TR Start/Stop, that I suspect the Battery is failing on (we've had the car for 5+ years and never replaced it - it may be the original!).

Just looking at the Helfrauds site in anticipation, and the only Battery they list is a Start/Stop EFB Battery @ £126.

The AA site (who we're members with) list a number of Bosch batteries (starting from £120 fitted), but the only one that mentions EFB is £165 😲

My question: does the Auris Start/Stop need a special EFB battery or not?

As I understand, a Battery for a stop/start system is not an “ordinary” Battery. Have you checked Toyota prices, worth a check.

As Catlover suggests, Toyota dealer-supplied batteries are menu priced, so one price for all the sizes that could go into an Auris (unless this has recently changed) .

If you have an expensive Battery, then this will work in your favour. I think it was £125 for any Auris. But there has been a spares price rise since I saw that figure.

The stop/start batteries are AGM or efb. These batteries are manufactured to take the strain of stop starting and allowing for an over discharged state. A standard Battery will work but will not last very long.

Hello all,

Is there away of checking the Battery to determine if it’s fit for purpose i.e. Stop / Star

Thank you

Hi. A Battery that is to be used on a start/stop system will be marked with either AGM or EFB. If there are no markings then it will be a standard Battery which will work ok for a time, but will not last as long as the correct types.

Although the Battery may well be past its best at this age you don't actually say why you think its failing.

If the ratings check out, then the Halfords option will be good value! I looked also looked at Euro Car Parts, and even their cheapest EFB is price using discount of the time, could be very cheap for their own brand Lion £184.99 minus whatever discount code being active (upto 30%-50%), or the pricier brands (Bosch/Exide/Varta) price £250-£275), again with discount code. National tyres cost £162.50 including fitting. 
All the above you have shops to get to, and except EuroCarParts, there is a fitting service available. If you can fit the Battery yourself, then try the Battery specialist online to get a premium quality Battery at good value.
That's my little input.

Still could be pleasantly surprised at Toyotas prices. Anyone enquired?

[jonny123456]

Thanks for the replies all.

At this stage I was just enquiring as to whether the EFB Battery was necessary,or just some marketing BS, but it appears to be necessary (so thanks everyone for confirming).

At the moment I'm not 100% sure if the Battery does need replacing.  The car had been unused for just over a week and wouldn't start without jump starting.  It's been fine since, despite only doing a few relatively short journeys.  I guess we'll just need to monitor it for now....

When the time comes, I'll be sure to try Toyota too.

Providing the car is standard... as in no after market electronics added that may or may not draw current when supposedly off... then it should be able to be left for several weeks 'as a one off' before any concerns over starting would apply. 

If the car is standard then it could be the Battery is failing. Jump starting will get you going but it takes many hours of charging at the correct voltage to bring a Battery back to full charge... or many hours driving. An hours driving might put back 40% of the charge, but it may take another 5 hours to bring that to 70% and another 20 or more to get to 90%+. 

A rough and ready test of a charged Battery can be made by switching headlights and heated window on with the engine not running. A new battery should support that load for quite some time, at least 60 to 90 minutes. We would never try that on an old battery but it should certainly be happy for 10 minutes or so and still then start the car normally. If the battery makes any fizzing, bubbling or hissing noise when discharging like that then its definitely faulty.

If there is a very cold frosty morning and the car has been left in the open.... that will test the Battery.

And if the car has only been used for short runs.🙂

yes the 1.3 auris stop/start is EFB, replace with the same type, as the charging system is designed for that type of Battery (deep cycle, high cca)

 

imho try Toyota for an oem Battery you may be surprised, if your going aftermarket go with Bosch, Varta or Yuasa
