Comparing Gel-Cel versus Absorbent Glass Fiber Matting Batteries

i have taken it that the YTZ7s was the business and certainly the name YUASA is well known and helpd in high regards.

however, i've spoken to a couple of specialists that reckon that the CTZ7s is a better battery and a dealer i spoke with checked the CCA as 159SAE.

the yuasa YTZ7s is down as producing 110CCA (EN) according to some but we have it down here at UHE as 130CCA.

i'm now told that Gel-Cel is old hat and that AGM is better whatever AGM is?

comments?

Absorbed Glass Matting (AGM)

They are totally maintenance free, and totally sealed. and they will accept a much higher charging current, and charge fully with a lower voltage. They are also less likely to die if discharged below 50%.

They were apparently developed by the yank armed forces, and word is thay are the ducks nuts.

CT are another battery manufacturer, quite commonly used as original equipment by many of the Far-East bike manufacturers.

AGM batteries have been phased in over the last few years by most of the major manufacturers to replace gel-electrolyte technology in automotive batteries and some other applications. In an AGM battery the acid is in a liquid state but held suspended in an Absorbent Glassfibre Matting material so the battery can be mounted any way up like the earlier versions and also it will not leak to any serious extent if punctured. The main advantage of AGM over gel-electrolyte is that the electrolyte stays stable for longer as it is not affected by the drying out of the gel material and subsequent cracking which will cause unreliability.

Any battery of the same type number will do the job perfectly well as they will all meet the minimum standard that the bike manufacturers use when choosing a battery type for a particular model.

CCA (Cold Cranking Amps) can be measured in several different ways. Varta publish an EN rating but other manufacturers publish DIN and SAE ratings and these cannot be compared like for like. All these ratings are however often optimistic, particularly from the less well known manufacturers, and they can only reliably be used to compare the output of different battery models from the same manufactuer.

is there no comment on this? FFS? the guy is saying that your YTZ is a piece of junk and what do i get? not a word!

where was this info when i went to start the 450 a couple of weeks ago and got cllliiiccckkk? :angry: gonna have to stick with the new ytz for awhile. and the one in my 650 is less than a year old, but will not do a sustained crank for more than 5 seconds. luckily, it usually starts in less than a second.
it seems to me that asking a battery of that size to crank a big bore for any length of time is a bit much.
i mean...ffs.

hahahahaha! you're speaking my language now!

i think i told you in a PM ned that i had a 470FX or FC and the lad had a shagged out decomp in it. i suggested he might like a 'dutch clog' (up his arse probably!) to which he said why?

he then sent over to his bike with the original 'weak' starter, and it started immediately. the engine spun really quickly and lest we foirget, the 470 may be smaller than the 650 but it has way more compression. it swatted the compression like a fly.

the reason? well under the seat he had a huge 11 amp battery.

so i tend to think that we still have a way to go in all this. the battery has a lot more to show.

anyone got the specs on the CTZ? can we compare the SAE and the other one?

Re: RE: batteries

Quality products too Taffy, installed them on loads of boats, never had a problem, and if we did(normally customers fault), they swapped them without blinking an eyelid

ok i just bought an equivalent battery to the ytz7s, its an AGM battery but it has 6.5 ah but not sure on its ccs, now i pulled old battery out of bike and its a ctz7s, so is that ment to be better?

its ok my ctz7 is an exide not the same as the yuasa one or wat ever.

my motobatt mbtz7s fits perfect, its 6.5ah and is an AGM, fired bike up like a trooper so hope its good.
 
I have found that JoeT's 5Ah TurnTech Li ion batteries out performs the YTZ7S batteries in both of my high compression (12.5/1) bikes.
 
hope so its twice the price and half the weight, very temped to get one but needed bike for this weekend ride.
 
changed 2 batterys this week, both varta. after looking at them they both have a agm logo at the bottom, they are also branded funstart, are they the new type if so they didn't last long.
 
Check out these batteries http://ebattonline.com/index.html.

I purchased the 8 cell and it easily cranks my '02 501, even when it's cold. It is small and very light weight. I would recommend looking into one of these. I got mine from MotoXotica.

Would it be possible to wedge a YTZ10S in?
Also, I’ve seen a TTZ7s advertised on MDS as a replacement for the YTZ7s but they don’t list a CCA for it, can’t find it on the Yuasa site either.
 
Had a Varta YTZ7 in for the past five months with no problems, before that two CTZ's that only lasted a few hours before going belly up. Cost about £40 from Bardens batteries, starts my old 650 from cold without any problems.
