Battery Types

My R6 requires a new battery. The type is a GT12-B4, but due to a garage
fuckup I've managed to end up with a CT12-B4, which is slightly narrower.
My question to the foak is whether the batteries are completely
incompatible, or whether it's worth just going with it. What differences
are there between these batteries? It is just dimensions, or rating, or
what?

You have the right battery for a 99-00 R6 according to
http://www.bitzforbikes.co.uk/producttyperes.php?ProdTypeID=25&BikeID=427&submit=Next+>>>

That site does not list a GT12 either. Has some Japanese linguist made a
typo when doing the label for the other battery?

 

I don't know; the battery boxes are in some oriental script

That's my hunch too. It's obviously the same voltage, they're both normal
lead-acid batteries. The only difference can be the current they supply,
but I seriously doubt there's that much difference.

Sounds like the best plan. The battery does actually fit, so it may
actually be a compatible battery after all. There doesn't seem to be much
information about this sort of thing on the interweb.

 

Thanks for that. The GT12 is what the Haynes manual states as well, so I
guess it's probably what they spec for the bike. But the CT12 can't be
/that/ wrong, I think I'm just going to run with it and see how I go. After
all, that website says that I should be running a CT9-B4, which is
completely different again!

 

Slider says...

There is no difference in spec between the battery you had before and
the one you've bought. The GT12-B4 is made by GS Batteries, who always
start all their part numbers with the letter G. Most Yuasa part numbers
start with a Y, and the rest of the battery manufacturing industry
tends to go along with their numbers, GS just like to be a bit
different.

The CT12-B4 is the normal designation for the battery you need. The C
at the beginning denotes either a maintenance free or sealed battery.
Sealed ones can be laid on their side as fitted to Yamaha R1s, yours is
maintenance free and must be installed upright.

Thanks Lozzo, that's reassuring. As for the battery's orientation, there
was only one way that it would fit, so I've got to assume that it's correct.

Oh, the other thing I forgot to say is that there is often a slight
variation in the dimensions of the "same" battery from different makers.

I just installed one of the new fangled AGM batteries to the GS. This is
slightly narrower than the OE. Easily sorted with the judicious placement
of a strip of cardboard from the packaging.

 

The important parts are the voltage, ampage and charge rating of the
battery, inside if they are the same then it should do the job fine.
