2007 cbr 125 won't start unless jumped and only runs for a few seconds

Has the OP had his battery load tested at CTC ? said he was going to right away- and still hasn't ? That was 11? days ago?

You don't need to go up north to have your battery load tested. First things first - get the battery load tested ! and replace if req'd. Sheesh, simple instructions.

If you don't have tools your motorcycle tool kit would suffice to remove the battery. Best luck, and whatever you do- double check that you don't mix up the neg and positive terminals when installing a battery. This is critical.

Dies and shuts off I can't get a video of it now because I don't have the cables. What do you think would be wrong from leaving the lights on other than the battery cause it was working right before that

does it die out when you remove the jumper cables? or does it die even with the boost battery still hooked up?

Whats a battery tester? Proof read your replies for clarity.
As stated to you by others long ago - the only way to determine if your battery is good or bad is through a load test - at ctc or auto parts place etc.. wtf.

I tested it and the battery is done so I bought a new one it's coming this week I will just need to get it filled and charged. Is it worth doing myself and if so where would I get the acid?
 
If it is not already filled - It should come with the liquid to fill it in a special container that is designed to dispense the right amount into each cell. That stuff is sulfuric acid, which is extremely nasty, so follow the instructions carefully. Upon doing so, normally the battery should have sufficient charge to start and run the engine without doing anything further. Do that, and go for a ride.
 
That battery is not suitable for your bike. It is an open (vented) flooded lead acid battery, not a maintenance-free type. The slightly higher charging voltage designed for a maintenance-free battery will constantly boil water out of the battery. And, your bike does not have a connection point for the corrosive gases that will be emitted by the vent on that battery.

The other thing to check, which I don't remember offhand, is the installation orientation in the bike. Flooded lead-acid batteries have to be installed straight up and down (obviously the caps pointed straight up). Sealed maintenance-free batteries (like the one originally in your bike) can be installed at an angle. The thing that I don't remember, is whether the battery box in that bike has the battery straight up and down, or tipped over slightly.
 
OP- where are you at with this ?
Did you get the battery tested ?
Its a maintenance free type, if its toast just spend the money on a GOOD QUALITY replacement.
 
The correct battery for your bike - a maintenance-free type, without the push-in easily-removable yellow plastic caps - should be delivered either (A) filled, or (B) with a special container with 6 little chambers each filled with the pre-proportioned amount of sulfuric acid for each cell, and with a replacement strip of caps that you permanently install on the battery after it has been filled.

If that's not what you get, it's either the wrong battery or you bought it from the wrong supplier (or both).

The sting of poor quality remains long after the joy of cheap price is forgotten.
 
I don't have FI on any of my bikes - so I don't know what I'm talking about - but if you jump one with a dead battery, shouldn't the alternator be outputting enough at idle to keep it going?
 
Ok than i went with the wrong battery probably i was going with the one that was in my bike and now looking at the owners manual its suppose to be 6 ah and the one he had in is a 3 ah and i went based on that. The one i got also isn't maintenance free.
 
I returned it so how do i know what maintenance free battery to buy all the owners manual says is 12 v 6 ah but they're is so many and i don't have anything to go off of.

These little bikes don't have much of a charging system. If the battery is cooked and dead as a doornail (which is highly likely, in view of what was just posted!) it's not guaranteed that the alternator will produce a sufficiently stable voltage with the engine at idle speed.
