Title: Battery type
Post by: ShaunMac on 02.03. 2013 11:17
Hi all,

I've not got a battery on mu Super Rocket and was wondering what the best type to go for was?
I like the look of the Lucas black battery cases. Would they fit?
What would be the best way?

Thanks,
Shaun *beer*

Hi Shaun - Some members here have said good things about these http://amalcarb.co.uk/batteries.html (http://amalcarb.co.uk/batteries.html)

as yet another battery goes duff on my Rocket (12 volt), I have eliminated  the ignition and voltage regulator from being the cause, I've now charged the thing up thrice and left it unconnected to anything and down it goes - flat.
So I'm thinking of trying these ( Burlen ones), strangely two of six volt ones come out cheaper than a twelve volt one and I think might fit into the battery space although I haven't measured it yet.
If successful then it probably would be good for me as my Flash is six volts and then three of these would cover both bikes (or two if I wanted to fiddle around a bit)

Thanks Bill. I presume the 5 amp/hours rating is sufficient for the A10?
My Haynes manual says 13, but I presume this will be for night riding etc?

Cheers,
Shaun

5 is perhaps a bit low if your using the bike regularly at night, although we should be aware that it's a six volt system after all.
a priceir solution would be the 12 volt battery they sell which can be configured to give 6 volts which would then be 10 amp (if Mr Tait my old science teacher was to be believed)

Hi Shaun
For my use, all day time riding, I have gone for the empty period battery box and single sealed 4.5 amp battery, purchased via VMCC for total of £34.00.
There,s room for two sealed batteries inside the battery box, so 12v option possible or 9 amp 6v could be achieved via wiring together.

Scotty, Do you by any chance know the model number of those Cyclons? would they be 0859-0010
(just looking at local (Aussie) suppliers.) gav

I have got one like this in (6v 13 amp lead-acid).
Love the look of it, and need the 13 amps because we need to drive with our headlights on during the day.
I regularly hook it up to a C-TEC charger too keep it in shape (the charger came with a handy lead set which you can leave on the battery permanently, and got a 2-pins connector covered with a rubber cap, so you don't have to take the saddle off when you want to charge it.

Morris, I'm a firm believer of running with the lights on, as I work investigation crashes.
Where did you get that battery from?

Cheers,
Shaun

They also have them in 9 amps

Thanks. My bikes missing a battery strap so I'm going to make a new one. I presume these fit in with the standard dimensions?

Cheers,
Shaun

This one will fit like a glove;

You're welcome.
Just note that they can't send the acid with it.
You'll have to get it locally (H2So4 sulphuric acid)
Also don't be as stupid as I was and overfill it, because when the battery charges, the acid heats up and expands.....
Fill it just enough to have the lead plates just covered

Gavinoz

Sorry but I'm far far away from my BSA at present and do not have the model # of the cyclon battery

I do know that each one was  6v 5Ah and i have them wired in parallel

I got the dummy case from Paul Goffs site as mentioned by metalflake but sourced the batteries locally.
They're the same battery as fitted to the emergency lighting fixtures on board a ship I work on.


They fit in the dummy case snugly and needing minimal packing to eliminate any wobble/shaking.

Not sure if this is any help but I use two 6 volt 5ah cyclon batteries wired in series to get 6 volt 10ah. They fit very nicely in the dummy box and can be wired for 12volt if required.

Would that be paralell, I think in series you get 12volt 5 amp
Title: Re: Battery type

Yes you're correct bill. 6volt 10 ah in parallel 12volt 5ah in series.

If you use your bike daily , it is not such a problem but if you use it infrequently then you really should use a Pressure Valve Regulated , Absorbent Glass Matt battery (PRV AGM ) and for our bone shakers , spiral would cells are even better.
Cyclons are the only battery that ticks all the boxes.
If you use it regularly then Scorpions ( or simiar ) will do.
Now here is the big trick.
Wire a plug to your battery so that you can paint over the connections leaving them corrosion free for ever.
Other members used to call me a liar when I turned the headlamp on & told them it was a standard set up , with a standard globe & running 6 V.
The difference was that the globe actually got a full 6 V ( 7 V when running ) because all of the contacts were clean.
There was a bod at one of the ABR's rubbishing the "Prince of Darkness" over his dull headlamp.
He had a 12 V A65 & when we measured the voltage at the globe it was 4.5V .
He lost over 2 V at the filthy corroded battery terminals before we got into the wiring proper.

I put a 6v 13 amp hour modern battery in a fake case on my 55 GF. I bought it here:
