Batteries

Ok folks, after a year of kickstarting the f*cker, I need to address the problem of the battery, and finally replace it!

I know that the model is a YTZ10S 8.6A but the Yuasas are about £90 each…

Anyone used something like this? Numax EXIDE YAMAHA FZ-8 FZ8 YTZ10-BS YTZ10S CTZ10S BATTERY | eBay or http://www.ebay.co.uk/itm/ULTRAMAX-YTZ10S-12V-8-6AH-FOR-MOTORCYCLE-MOTORBIKE-QUAD-BIKE-JET-SKI-/251298678575?pt=UK_Motorcycle_Parts&hash=item3a8291872f&clk_rvr_id=503330034313

Concerned that it may not fit, even though it has the right reference numbers on it…

Also, I haven’t got a clue on battery brands, so is Numax or Ultramax a cheapo brand that will die in 6 months?

Much obliged!

I have a Numax gel battery in the superduke … only good things to say 1 year in .

cool… I’ll ring them to check if it comes pre-charged etc because I don’t have anything to charge it up with and it doesn’t say so in the ad, whereas the ultramax covers all those points (and is cheaper)…

Could my SMC finally have leccy start again after more than a year???

I am pretty sure mine arrived charged and ready to rock but its a gel . Acid traditional ones you just pour in the acid leave it for a bit and then plug it in and its good to go … no charging required .

I have a trickle charger you can borrow if it helps

^ +1 got a charger if you need

Do you know why it died? How old was the battery?

About 7-8 years old from what I can tell… although the bike was seldom used. Then it got completely drained one day when someone left the lights! :Whistling:

Never recovered from then… I’ve used a charger on it but nothing. It powers up for a bit but loses all charge very quickly.

Just making sure its the battery thats dead and not the charging system.
There’s an eBay store doing a clearance on Yuasa batteries. Some as low as £40.

I’ve only used yuasa when replacing a numax battery in the Mille and the old battery in the gsxr.

These guys are spot on with next day delivery as standard. A replacement yuasa for you is £53 from them

That’s a TTZ10S rather than YTZ10S… not sure what the difference is?

I thought this was mine: http://www.mdsbattery.co.uk/shop/productprofile.asp?ProductGroupID=2046

Ignore just read the description: The new Yuasa TTZ range of batteries have been recently introduced as an alternative to the ultra-high performance Yuasa YTZ batteries which are fitted as original equipment to many of today’s top-of-the-range motorcycles.


But: CAUTION: This battery is no longer recommended by Yuasa for installations where it is mounted on its side. - unfortunately on the KTM, it’s on it’s side :frowning:If your battery is fitted this way we recommend replacing it with the YTZ10S which is approved for fitting in this position.

Is there an easy way to test the charging system? This makes me look more to the cheaper variants… haven’t found that store, do you have a link?

Ah boo you’ll be needing a gel battery then dude

So I’m guessing the Ultramax/ Numax are not Gel? :frowning:

Oh **** this is going to be more expensive than I had planned…

Try Tayna I think your fitment in a Yuasa gel battery is £54.80 plus £8 delivery.

They are very quick to deliver, usually a day or two.

Well the one Numnum had was gel as was my one that came with the mille

Just double checked and both numax and Ultramax seem to be gel… might go for the cheapo one as a test. :slight_smile:

Buy cheap buy twice

Yeah I know but I’m planning to sell the KTM so it won’t get that much use…

Honda subsidise batteries, so find the yusa model nr you need, then find out which Honda uses the same battery and get one of them from a Honda dealership for about half the yusa list price.

I figured the superduke uses the same battery as a 1600 pan, so got a yusa from one of the Honda spares places online for half the price :smiley:

I used the Numax as in our jump packs its numax gel … and despite the abuse those things get they keep working .
