I normally go on fleabay and order by physical size. So long as it fits and has about 5ah capacity you should be OK.

In my opinion Keith, if you are still running on the old mechanical regulator, you would be best to use the more resiliant  "Cyclone" spiral gutted SLA type.
If regulator is DVR2, then standard SLA,should be ok.
As HB says sizes are available to fit most boxes.

Original fitment was 13Ah for the battery.  You could probably go for two 5Ah Cyclone or one 8Ah?

Hi All,
On my recently bought Guzzi GTW I hollowed out the original battery and fitted a 8AH Cyclon into it
a tight fit but got a little dense foam in there to keep it snug
I was on a 4 day Rally a couple of weeks ago and noticed after a day or two I no longer had a brake light (considered essential)
A quick check revealed a flat battery  :(  I have not gotten round to sorting the charging yet)
OK so charge the battery, Bugger it would not take charge, so set about removing the case to see what was up
The battey has grown a "bulge" on the top between 2 cells so its buggered  >:(
It was a "new" battery but was sitting unused for a while

Bulge indicates poor charging regulation.

When they stopped putting screw-top filler caps on batteries they just changed in character. In the Olden Days you could keep an Exide battery in use for years by just charging it up after standing, to just get the horn working long enough for an MOT and the bike would do the rest. Modern batteries will just suddenly die, even when in constant use, if it's a sealed up one, then it can kill the regulator and also burn the alternator wiring out if you keep using it.

I've still got sealed up batteries in good order after many years but I had one fail in France one morning, dead as a door nail, on a three-month-old Triumph after we'd ridden it about three hundred miles the day before. In contrast, my daily-ride Triumph twin has a Screwfix alarm back-up battery on it that's at least eight years old. It's had a neglected and abused life, oil breath all over it and rattling about among spare plugs and spanners, but still holds a comfortable six and a half volts. I bought two in the same week and put one on my Thunderbird and the other on my mate's Dominator and they're both still in really good condition. The Norton has a magneto ignition and alternator, my Triumph has alternator and original coil/points ignition, Brian polishes his bike regularly (including the battery) and I'm a stranger to a bucket and sponge.

You can't out-think a modern battery. Sometimes, like a Suffolk sheep, they just die on you for no apparent reason.

Thank you all for your input.  I have been on Flea Bay ,E bay and every other bay.This is my third time on this computer this year so bear with me. I have a short list of 30 battery types?????? The one that appears to look good is The Shield ClassicB49-6 8AH What do you think?     Keith

Check the height again Keith. At 161mm it may be too high for your box.

That is a traditional "wet cell" battery in a rubber type case Keith.
I think we (well I did) all got the impression that you were intending to fit SLA in a dummy case :-\
A wet cell will work ok, but arguably, be less efficient, require maintenance, and cost more...but of course, is more authentic.

Don't confuse him any more Graham. It's already a minefield of choices.

HB. yes it will be to high to fit in the old box,but should fit in the carrier holder.but at £59 99 is it worth it.? I will probable be knackered before getting my monies worth out of it.
 Graham you are right I was going to fit the new one back into the old box,I lost my way on one to those Bays.So my choice is either another BURLEN battery OR  have you or HB or any of you chaps have a recommended one that will do the job.Bye the way I  fitted a DVR2 Reg some time back. Thanks for your  time and patience Keith
