(...and cheers, Northy! )

give my honda a ring ... not only were they not in stock but £60 (potentially +vat) … its not fair!

Get the 14 from Interbike then, £55. Or, if you prefer, give me £25 plus postage and I'll get a 14, and you can have my 12

Ok, so the YTZ14 seems a popular choice, I see from spec sheets it has a 230EN cold start figure 11Ah

The YT12A-BS which is the stock SV batt has 140EN 11Ah

The YTZ12 has 200EN but only 9Ah

Anyway! ...

There has been no mention if the cold start performance of the GEL batteries!

You can get a CT12A-BS (YT12A-BS yuasa?), which is the same dimensions, but filled with gel.

Anyone know what the Cold start figure on the CT12A-BS is?

According to the Yuasa site the

• YTZ10-S is 8.6Ah + 190 CCA = 3.2kg , 150 x 87 x 93mm
• YTZ12-S is 11Ah + 210 CCA = 3.7kg , 150 x 87 x 110mm
• YTZ14-S is 11.2Ah + 230 CCA = 3.9kg , 150 x 87 x 110mm
• YT12A-BS is 9.5Ah + 175 CCA = 2.8kg , 150 x 87 x 105mm

The clue is in the weight.

I had a YTZ10-S on my Deauville from new and it started that with absolutely no problem. Replaced it with a 12 because it would fit (didn't realise at the time that the 14 is the same physical size).

But what about the Gel batteries colds start?? Doesn't look like Yuasa do sealed at factory, use it at any angel gel batteries ... unlike the CT12A-BS
Which could be used upside down presumably?

Hold on a second ... I think I have just twigged something after reading some blurb and putting 2 and 2 together ...

Varta

"All Varta YT series "Liquifix" batteries use AGM technology which consists of an Absorbent Glass-fibre Matting between the lead plates inside the battery. This material absorbs and stabilises the electrolyte so the battery can be mounted in any orientation and also allows higher discharge rates without causing internal damage to the battery. AGM batteries are often referred to as “Gel” batteries because the electrolyte appears to be solid but they are also sometimes known as “Dry” or “Sealed” batteries. "

Yuasa

"Absorbed Glass Mat (AGM) Technology is an advanced battery design used in Yuasa's Maintenance Free Batteries that eliminates water loss. Once it's filled with acid the battery is permanently sealed - so you'll never need to fill it with water or check the acid level."


'Liquifix' (LF), AGM or MF is basically the designation for a gel battery (not actually gel filled at all!! ) ... the fact some look 'plugged' and others look properly sealed with hard plastic cover (like the CT) is not a clear indicator of type ...

Which means me having opened up my YT batteries and adding some distilled water as they looked a bit 'dry' might not have been such a good idea

Anyone know if this is detrimental to a gel battery?
