Yuasa YTZ7S AGM mounted on its side (hidden in a rubber case)
Got it in for about 4 years now and still holding charge well.

G'day RRC.
6 or12v?
I agree with Morris. The AGM batteries are the best. Get the biggest you can that will fit in the hole, or two smaller ones wired together may fit better (I have two to fit in the dummy case on the plunger).

Here’s the 2 AGM 6v Cyclon batteries I have in a dummy box on my chicken coop to power the door that opens /closes on a light sensor.
Gets a top up charge from a mini solar panel

Oh yes......I have the same battery set up on my A10  *wink2*

Never had a problem with them.

I use two Cyclons for 12v on my SR - they fit exactly in the rubber battery case. The 12v MK  AGM type seem to be a little smaller and need some packing and it is always best to fit the largest capacity battery possible. On my 6v bikes I use the MK AGM battery which again, fits exactly in the standard battery case.

I had three cyclons, two have  died, one of which went on fire, the other is still working but refuses to charge above 5.7 volts.
I found them impossible to charge if they get down, they need to be kept on charge, contrary to fit and forget adverts.
Maybe I got a duff lot

Some highly interesting literature about charging/discharging (AGM) batteries which may explain a thing or two of the above mentioned issues;

 I find batteries to be a bit of a 'dark art' at times,  I've had ones that I've Molly-coddled but they've died premature deaths, and others that''ve done it hard and lasted long past their u.b.d (mainly standard lead- acid), an example of that is a cheap 6N6-3B that's been in a Honda CL90 that I bought for a project with my youngsta mid-90's, used as a total-loss ignition for a while and then sat  unused for at least 18 years, probably 20, until I dug it out a couple of months ago and the battery showed 0.7 volts, but I put it on charge overnight, and it's been holding ~5.9 volts ever since....(as per pic). probably ruin much load for looking,  but maybe make a spark, and recharge if I can get a charge....

 I know enough to be dangerous,  but've been led to believe that AGM as above, but in electrolytic gel rather than SLA is the general best option...I have a Duracell labeled gel-AGM in the Gutzzly, that is supposedly a Motobatt in the US... *dunno*, but still goes flat if I don't treat it right.... *conf*
 Having said that^^, finding gel- AGM in 6v may be harder to find

This is what I have; bought from Paul Goff,(Norbsa). I've soldered cables to the battery tags and use a plug & socket on the lead.

 I use cyclons on my A7 but I was told that if you use Cyclons then you have to use an electronic voltage regulator not the old mechanical ones. I do not know why this so but have followed that advice and never had any problems.

I think that the old CVC units may overcharge the Cyclons and cook them - the electronic jobbies probably have a current limiting circuit. I use the DVR2 in my SR with Cyclons and have no problems.

I used digital voltage controllers on the three Cyclons although not DVR2 ( I have since changed to them), it seemed to me that the problems with them (Cyclons) is that when they get down they refuse to be charged, faced with this I used an large old charger on them for a short time, this did indeed put a volt or three in them, then I was able to charge them up with a modern unit, however two of them did not last long after that.
As with most stuff these days there is always the chance of a duff lot, not sure that quality control is an automatic feature of modern manufacturing, could well be it falls down on cost effectiveness ( bit strange to say that but if your only getting two duff units out of several million ???)
