SQ4 battery carrier

Postby greg.geonetta » Sun Mar 20, 2016 5:52 pm

Trying to get my MK.1 project together before it gets too hot here in Arizona. It was a basket when I got it and missing lots of parts.

I have a battery carrier but I don't think it's the right one. It might be off some other Ariel, a single maybe. Image

Can I use it anyway? What battery might fit?

Thanks!

Greg

Ariel introduced a different battery carrier for 1951 Greg, with a much larger battery. The one you have is the older one for the smaller battery.

There are some pictures of the 1951 version here:

Does your speedo mount in the fork yoke, in the tank or in a sheet metal pressing above the fork top yoke?

What letter prefix does your frame number show?

My speedo mounts in the fork yoke.

Frame VIN is SC999 - I believe it is a late 1951 model.

I don't care about having the absolute correct battery carrier, if the older one will work.
Is the smaller battery a potential issue? I guess there was a reason they changed it.

What battery do you suggest?

Thanks!

As far as I know, Greg, nothing else changed around the battery carrier that would prevent the early carrier fitting to a later machine.

The reason they changed the battery was, I believe, one of capacity. I found while running my bike on very short, local shakedown runs of 2-3 miles that I could flatten 20 Ah of battery quite quickly, which means that you are pushing a heavy bike home; now that I'm doing much longer runs the battery is spending more time on charge, with the higher engine speeds and this has not happened since.

Of course, if you live in some wide open space, with hundreds of miles of roads available for biking, short trips may not be a problem!

As you will have seen from my blog, I have two batteries in parallel in the big GU11E battery box. The older carrier was not designed for this big battery, and you will need to use a smaller battery or battery box: I would look at some battery dimensions online and fit as large a battery as you can into the space you have.

It's also well worth fitting LED side and rear lights to reduce the current drawn.

Thanks for the info.

I live in Arizona and we have plenty of wide open spaces, you can almost always be over 40 MPH here, at least.

I'll see what I can find to fit in the carrier I have.

Hello Greg,
Many other owners and I have fitted a small gel cell battery inside a hollow copy of the original Lucas battery. These copies (PU7D/KOR) are available at:

I've been using these batteries for a few years on my 1946 Sq4 which I have modified to electronic/coil ignition:

Any similar battery should do the job with no problem.

Regards, Chris

I'd be interested to hear more details of your electronic ignition, Chris. Have you made any changes to the charging system?
cheers

Hello Greg,
I think that your battery carrier is the correct one for your bike. Some of the 1951 Mk1 bikes had a smaller battery fitted especially when they were equipped with the big "colonial" airfilter. This might be the case with your bike. To make sure try to fit the carrier on top of the primary chaincase just above the chomed clutch cover.

Hope that helps
Kind Regards
Klaus
