batteries

That's weird it's going dead like that when it's only about a year old. Mine is 2-3 ish years old and it stays charged without a battery tender. I wasn't to sure about your wording, did you say that it go dead if it's not on the tender? And if it's charged how long till it goes dead?

Hi, bought this one about 3 years ago. Seems fine. Touch Wood!!

Hi to clarify, it stays on a tender when not in use and until today it was fine. I switched it on this morning and all lights and ignition came on. I turned the key to start it and it all went dead, not a geeks out of it. I put it on a proper charger and it is dead to the world. Very strange i have to say. I have to go and buy another damn battery. Bloody cold weather we are having i will have to put it down to.

Cheapest i can find is Halfords @ €66 euro for one

I have 3 old ones on the shelf and owned bike about 5 years...

The battery before this one lasted for at least 4 to 5 years so i dunno what happened this one. It is a Yuasa battery the same as the previous one.

mossproof · Super Guru

Definitely not a corroded earth? Lights all coming on then going out altogether suggests something like that to me. Can you check the voltage?

jasparach · Senior Member

I don't think so but i will check it tomorrow. It seems to be a total failure of the battery. When the last one finally gave up that is the way it went , complete failure.

The original batteries are made to the bikes manufactures specks after market even the same brand are built to a price / standard set by the battery manufacturer with the aim of making a profit a combination of cost and planned obsolescence

for example most original batteries last a min of 5to 7 years on average replacement batteries 18 months to 3 years is a good run

easy check us as you have done turn lights on it’s ok add the starter load and the lights die only options battery conectons or battery if it was for example starter brushes the starter would not draw much current and nothing would dim

most Likley an open circuit or poor cell conection would show 12.5 volts no load and die under load

or cell failed lead accumulates and shorts individual cell no load voltage may below 12.5 and die under load you may also hear the cell bubbling while under load take the load off recovery voltage would be around 10v

I'm happy if I get 5 years out of a car battery, my landcruiser battery is still going from 2011 so its seven years old, but its on its way out i think. It goes flat after two weeks now.

Bike batteries are smaller so if I get 5 years I'm really happy.

I've had good success with the new super lightweight lithium batteries. They seem to have more power and hold their charge longer. Expensive but.

On ebay batteries range from about 30 bux to nearly 200. I think you get what you pay for (sometimes!)

I think the trick is to give them a decent trickle charge occasionally if they are not being used often

if yours was on a battery tender I would suspect the tender might be dodgy.

I have a cheap tender and it cuts out charging before the battery is fully charged so I don't use it any more. For instance if I take it off the tender the trickle charger will charge it up further.

That makes perfect sense to me regarding the original and after market batteries and their respected performance even within the same brand batteries. Mine tested on a volt meter shows 13.4 v but connected to the bike gives nothing at all in power, no lights, no ignition lights, nothing. Going through my records i bought it in Sept 2016 so it is 18 months old. Looking on Halfords website for a replacement it shows that it gives a 2 year guarantee so i might try bringing the old one back and see if the guarantee will apply as i bought it there and it is the same battery brand.

I managed to get 12 years out of my merc vito battery (varta) and I thought that was living biggrin

I spoke with Halfords today and i can bring it back and they will hopefully exchange it for a new one, Just as well i kept the receipt for it so i will see how it goes. I am hoping i can get an exchange one and that will leave me with just one buy for the white OE as that one is starting to fail now as well. That one is 3+ years old and is a Kyoto battery , whether that makes difference or not i dont know. So once the snow starts to melt and travelling is once again possible away i shall go.
12 years is a fair length of time to have a battery, must be a record.

skyrider · Senior Member

yes I was well pleased, I also have a daihatsu sirion which is an 02 and just changed the battery on that just before Christmas and the fitter said it was an original fitting, perhaps I just have good luck with batteries

Bike shop Mechanic told me lack of use is the killer with modern gel batteries .
In regular use they should last a few years .

Base · Senior Member

If the battery is of good quality and in good condition, then left on a standby charger it shouldnt go flat.

Yuasa is a good quality brand and as long as if was sized correctly there shouldn't be an issue. But even good quality batteries fail from time to time.

It may have a surface charge (voltage) that suggests it's ok but measure it whilst youre cranking and it will drop severely.

Had one die prematurely in my car not so long ago, about 18 months, thought initially it was the alternator but just turned out to be a faulty battery. Replaced under warranty.

Think TTR uses either an AGM or Gel battery due to its mounting position.

Just checked the invoice. 3 year warranty on gel battery, and i have had it 4 years and not used regularly.

So am on borrowed time. :)

That's a good length of time to have it and still going strong. Available for a good price too.A pity i cant get it over here. I brought mine back to halfords today and got a replacement battery so hopefully this one will last a bit longer. Not wanting to be too negative but it is amazing how little the staff know about how long the guarantee is on the battery even though it clearly states on the spec sheet of the battery that it is two years and that is on their website. I made off with it quickly in case that she decided to change her mind and take it off me again. So instead of two years i now only have six months warranty on it which would have been the end of the previous battery's warranty. At least i have new battery.
