I used to own a Honda Deauville NT650v and we all used to upgrade the YTX9bs battery to the much more powerful YTX14bs...... although this was a bit taller, the width and length were the same, it could just about fit in and made quite a difference to starting the bike.... had so much more go in it. I've now gone backwards to an old NTV650 and need to replace the battery....... has anyone tried fitting the larger battery?

Eh, no, but I did replace my battery for a new one of the same size.....that made quite a difference already.
The NTV doesn't really need a bigger battery for most things....

Thanks...... it's strange that on the Deauville site, just about everyone would replace their battery with the larger one when the old one needed replacing, particularly as it is virtually the same engine. I found that the larger one gave a significant boost to starting, particularly on those cold winter mornings.

Apparently (says a bloke down the pub), the Deauville has a similar wireing loom as the Pan European - so there's a lot of extra sub-looms which plug into it for the heating controls, Aux plugs, Radio, etc.
Whether this makes any differance to the amp hours required from the battery I'm not sure

I attempted to buy a larger battery(ytx14) for my ntv, it was a lot larger and i`m not sure it would fit also the bloke in the shop said it would blow stuff, not sure if that is true as a battery is only a bucket of sparks

That`s absolute ARSE GRAVY, of course it cannot blow anything it`s simply carrying more stored energy not a higher voltage!

Just changed my battery last month after 4 years. My bike lives outside and starts first time in all weathers. I would buy the same one unless you plug in lots of toys.

I did buy a cheaper battery-big mistake, the posher battery I have starts the bike after half a second not like the churn the other cheaper battery did Ray |

I'm attempting to make contact with this company Racing Batteries for my project as it's nice and small to hide in a single-seat hump. Lithium Ion - no way, that's old-school. These are Lithium Ferrous Nano Phosphate |

Well I had a close look and there's no way a taller battery will fit.......... the battery positioning and seat are significantly different to the Deauville where you could squeeze in the taller battery with no problems. Pity.... I'll just have to replace it with a decent yuassa battery as previously fitted.

These are Lithium Ferrous Nano Phosphate A good friend tried one in his NWS framed TRX special and duly fried it, a replacement lithium Ion never suffered the same fate. That said it IS the way forward if saving weight and space is on your mind.  I intend to go a similar route on my own TRX fighter (one of these days). |

Pikey - that's a bit worrying, it's making me wonder if it's the right route to take now.
As far as I can tell, the standard battery (YTX9-BS) is 12 volts, 8amp hours & Cold crank start output of 135amps at 150mmx70mmx105mm (L/W/H)
The other unit being talked about (YTX14-BS) is 12v, 12amp hours, 210 cold crank at 150mmx70mmx145mm (L/W/H)
There is the YT12A-BS which has the same dimensions as the YTX9-BS but has 10 amp hours and a CCA of 175amps
I've been doing lots a research into loss-less systems, closed-systems & total loss to help find the best starting power & trying to work out the drain a NTV has on the electrical system as I've noticed my bike is struggling to start during these minus degrees.
Thread hi-jack moment: Would moving the stater motor closer to the battery (with a thicker/less resistance wire) or replacing the coils with in-lines help?

Current drop COULD be less if you repositioned the battery and associated components in the wiring circuit yes. As for in-line (pencil?) coils, possibly. But, how tired is your motor, could be compression `leakage` when cold that makes the old girl difficult to start. |

Thread hi-jack moment: Would moving the stater motor closer to the battery (with a thicker/less resistance wire) or replacing the coils with in-lines help? Thats interesting that the YT12A-BS is the same dimensions (I think the width of the batteries is actually 88mm rather than 70mm but as you say, they're the same) but significantly higher capacity and cold-start performance.... all for an extra £10 approx...... I'll have to give that one a go. You'd think Honda would fit the highest spec battery that would fit in the space but then I suppose they want to keep the costs down. On the deauville, we always used to fit the YTX14-BS but there's no way that'll fit being so much taller. I don't think reducing the length of the wire would make any difference as its resistance is pretty negligible........ when you think how long jump-leads are and they work fine. |

I did use a bold could in my reply Actually current drop does occur and add to that the effects of the cold on lead acid batteries it can make starting difficulties rear their heads. Using larger diameter and good quality wiring on a starting curcuit can make quite a different. Ever used cheap jump leads that simply burn out or indeed do not even carry enough current to make them remotely useful? I have some truck starter leads with large clips as jump leads, voltage drop is minimal. Anyway, I think the YT12A-BS would be the way to go if you want to upgrade with standard positioning etc. |
