Ladies and Gents, 2 questions regarding Electrics if someone can help please, because I am useless at electricals :help:.
(1)I have an old style Autocom active plus which works very well but utilises 9volt radio/smoke alarm type batteries. It runs for about 2 hours of communication and music when I am touring but then slowly fades to nothing. A good trip around Europe can cost me £20 in batteries.
So I bought a converter that slips into the power output source of the bike and converts to 9volts.
But this is what I don't know and perhaps we have some electrical gurus that can help me please.
The output source says 9 volt and 2,000 milliamps.
I am told (google) that your average radio battery puts out 9 volt at about 500 milliamps.
So if I wire the system together will the addl 1500 milliamps blow my Autocom?.
Thanks all...
(2)Off to Halfords now to buy a Motorbike battery for my offroader DRZ. The standard battery just about cranks it over as it has had a new larger head put on it, and a kick start system.
What I also need to know is "Can I put another higher output 12 volt motorcycle battery on it, like say one recommended for a 1,000 cc bike, without blowing all the circuits.
Thanks again Guys :ohplease:.

Not exactly an electrical guru, and others will correct me if i'm wrong, but i thought that if your source is rated at 2A, then that's the max it will be able to deliver. If you only use 0.5 of that, then you're fine. In your case it's the voltage that's important, ie. to have 9v. Just make sure it's all protected with an appropriate fuse... 12v might even work, but you'll be more likely to overcook it.

For the battery problem it is similar. You need to draw more current so you'll need a stronger source. However, in this case you need to ensure that the cables and fuses are able to cope else you might end up melting stuff, or worse - fire / explosion risk due to short circuit of melted cables etc...
I hate electrics :help:

:agree: With both answers.
The voltage is the important bit in both cases, as long as it can supply enough current to do the job the extra capacity does not matter.

im a qualified sparky and the above answers are correct, 2000 ma is the max the converter will deliver , if required , so its good to use,
Hi Gents, thanks for all your help. Really appreciate it. I shall now wire it in and give it a go.
But with my fingers crossed :punk:
Thanks.
Yup, get the voltage and the polarity right and the rest doesn't matter much.
The current is drawn from the battery/power supply by the gadget, rather than pushed in from the battery.
However, try to run a 2Amp gadget off a 0.5Amp supply and you are going to fry the supply.
Thanks Boomer,
Haven't done it yet. Weekend job I reckon.
