Cheers all anyone got any links or numbers for the different types - meaning like YA 14sb etc

THANKS :)

the number of standard battery is YTX 14 BS.
Motobatt has a different number, its a universal battery, the terminals can be mounted on any corner, it has a spacer for height adjustment, gel filled, no leaks !
YTX means maintenance free, 14 BS relates to size ect

YTZ 14S has higher cold cranking amps; 230, instead of (?) 180 than OEM spec battery. I.e. has more of the necessary oomph for starting a big v-twin.

Some brands have a different prefix (e.g. TTZ, CTZ . . )

from the book keeper on another site

YTX-14BS - 200 CCA

YTZ-14S - 230 CCA
http://www.tayna.co.uk/Yuasa-YTZ14S-Hig ... P8565.html

I know the YTZ is more expensive (but you can get them for around £65 on ebay - http://www.ebay.co.uk/sch/i.html?_trksi ... &_from=R40) - but the extra CCA is, IMHO, worth it.

The one on my Futura is now going into its fourth winter; the bike lives outside, under a cover, the battery is always on a trickle charger; it's never let me down, even in sub-zero temperatures.

and if you are interested in such things this was good

Looks familiar . . .

so unsurprisingly I am now confused I am looking for the extra kick one that you mentioned above mart but does it matter if I get whichever one of the yuasa or motobat as the wemoto and others say motobat isn't gel but "just" AGM

amazon say not

and it doesn't help that i have been inhaling moxa all night

Why is it that you still get excited when you get a part for your bike even though it's only a battery??

Mines charging!!!!

Although I've a YTZ 14 S which has a higher CCC than the YTX 14 BS, the daddy for starting oomph (technical term) is the YTX14H-BS (CCA of 240 ampere)

Because as I can't ride for the foreseeable future it keeps me happy

so ...

This one then?

fatboy · #26 Post by **fatboy** » Fri May 24, 2013 7:27 pm

What's AGM ? Surely the G stands for gel ?
IMHO dont bother with Yuasa, just paying for an over rated brand name.
Gel batteries seem to be good at handling extremes of use, my mate maintains a fleet of hire narrowboats,they use only gell filled batteries because they can handle the abuse the clueless customers give them !
Cant comment on YTZ batteries, dont got one.
Can say cant fault Motobatt, fitted for almost a year, no worries, no probs !
That includes loads of trial starts sorting out fuel problems

flatlander · #27 Post by **flatlander** » Fri May 24, 2013 10:28 pm

So that was the right battery then :) ???

Stands for glass. Honest.

AGM = Absorbed Glass Mat. The battery is filled with a fibreglass type mat which absorbs the acid that you put in, turning it into a gel-like substance. Almost all batteries on the market of this type, it is what makes them maint free. Very few are true gel batteries despite claims that they make - proper gel batteries are around twice the price of an equivalent AGM type (IIRC) and contrary to popular belief still need to be maintained in the same way if they are out of use for any period of time.

As regards CCA and Ah, yes the CCA is the amount of current available for a single start whereas Ah is the capacity of the battery(the amount of juice in the tank so to speak. IMHO although these bikes do need a fair kick to turn them over, if you have a new, fully charged battery it will turn the engine with no issue at all. Therefore the issue isn't with the ideal output of the battery (CCA), it is with the capacity of the battery since all issues revolve performance with a partially discharged battery, be it after a period of inactivity or frequent starts without giving the battery a chance to fully recharge.

I am currently (see what I did there?) using a Motobatt MBTX12U which is the equivalent of the YTX-14BS. I store my bike in a building with no power so it is very difficult to connect any kind of trickle charger and it has coped admirably with the past winter. Previously I have always bought Yuasa and if I'm honest I don't consider them to be much better than a lot of budget brands, although cheap batteries can be very inconsistent.

Oh, and the reason for two different naming conventions (YTX, CTX) IIRC is that the accepted designation was CTX however Yuasa decided to be a bit different and substitute the C. This has now been adopted by other manufacturers for whatever reason.

At the risk of repeating myself, the YTX14H-BS gives the best of both worlds. An even higher CCA than the YTZ14S and a capacity the same as the YTX14.

Personally I'd sacrifice a bit of capacity for better CCA - it helps starting and once it's started you don't need a lot of spare capacity to keep starting it again

Specs compared from the Tayna website:

That said, cost is also a factor and that may result in a different choice than looking only at the capacity and cca
