Using the Wrong Battery?

[BoB3rt]

hey,

I have a track bike am going to use every now and then bu have a 2 day session tthis coming weekend and dont know weather to fork out for a battery or use my ZX6r battery which i have used to tick over the GSXR750.

Am presuming it is not a gud idea as the diffrent alternators will charge the ZX6r battery wrong or too much? and if the gsxr is going to be at constant high revs .. it will charge!

anyone help me on this or simply buy a battery?

[rennie]

depends on the rating of the batteries and

alternators! you might be ok you might not!

As long as they are both 12 volts there should be no problem, just check the terminals are the same way round on both batteries and the battery fits in without fouling anything or the terminals being too close to the frame.

I have a ZZR 600, a Honda Bros 400 and a GSX 600f, I only have 1 battery (cos I'm tight ) and swap it between the 3 bikes

It will be fine as long as the battery fits

the ZX6R uses a CTX9-BS

The GSXR uses a CT12A -BS (i know he CT is just he manufacurer though) but the 9 and 12 look a bit worrying lol. am sure the ZX6r is 12Volt batery though... it fits the casing fine wih the connections he right way too.

I've never heard of a 9 volt bike, or car for that matter

I would say if it fits it'll be fine

one is 9 amp hour

the other is 12 amp hour

[rennie]

So! there is a slim chance that the bike meant to

run the 12Ahour battery would overcharge the 9Ahour battery.

And if you didnt know, its nothing to worry about but this only means the battery will last for 1 hour if all the consumers ie headlight, tail light etc etc were drawing 9 amps of current, if they were drawing 4.5amps then obviously it will last 2 hours.(Allegedly..dont take it as gospel as newer bikes need a good voltage for the ecu's etc to function)

Like the masses say if it fits then it will be ok, the only thing you really need to worry about is CCA (Cold Cranking Amps), lets say your starter needs 225CCA and the new battery is 180CCA, the starter will still try and draw 225A from the battery, the starter wont get the current it needs so cables will get hot, which will change the resistance and may make the cables breakdown, melt etc etc

A perfect example of this is those cheap crappy jump leads you get, you attach them up to the two cars they get hot and stop working.

Sorry you can all wake up again now, I have bored you to death with batteries.

Is this just when the bike is starting then? The gsxr has been started with the ZX battery plenty of times and goes first try... fits fine in the tray and connections are he righ way round.

Hi

The CCA is used for under extreme conditions ie

-25 degrees

Oil Viscosity(Its ability to flow) Obviously in cold conditions the oil will be thicker, the "W" in oil ie 10w50 means "Winter" so its ability to flow is decreased

New Engine

The starter may need that sort of current when the bike is any of the above, or all of the above conditions, so if you had a new engine and it was stupidly cold outside then the starter will need more current to turn the engine over, with it being a track bike I would say the bike will never need that sort of current so you will be fine just if its if we get stupid and start putting a 125CCA onto a bike that needs 250CCA then you may get problems, but dont worry about it

I was thinking about that when I posted last night and wondered if I worried you. But I hope that explains a little better

[BoB3rt]

Indeed that is alot better

however the only other thing that worries me is the bike charges the battery with the alternator and its worrying if it over charges it?!

No it wont Regulator will sort it out for you.

Hi, so long as the battery is the right voltage and strong enough to start the motor there should be no problems. The main things to watch out for is, makeing sure the battery is secure - well strapped in, vibration especially under track conditions could cause it to come loose or even crack. The only thing that can damage the alternator and regulator unit is a dead flat - knack battery.
