04-21-2012, 03:25 PM
I decided i wanted to replace my 10 year old battery and get the expensive ballistic buell battery for my 2004 xb12s. When i installed it fans turn on by themself even though engine was cold. nothing turned on with the key on on position. didnt seem right so i swapped back to old stock battery. every time i turn the key on it blows the kew switch fuse. Looking for some help cause there are no nearby harley shops.

Ouch. I literally just replaced the 6yo battery in my '06 XB12Ss yesterday with a Ballistic 12 cell and it's running like a champ.

Hope you get sorted.

has anyone else put the 12 cell in their bikes?

Ballistics keeps telling me to buy the 16HD but i'm not sure it will fit.

Please anyone comment on the fitment of the 12cell b/c it's a little thicker than stock. How does the battery fire up and is it reliable?

And anyone have the 16HD? Fitment ? Fireup?

Are you sure the polarity was correct when you installed it.

after hearing of problems with these, especially in buells, I opted out for a lead for $70. I couldn't chance it especially with accessories in the future like gps and fog lights.

One of the guys on here had a 12 cell twice with issues and then got a 16 and is having issues. He asked me where i got my lead batt. for cheap...so that didn't do any good for ballistics reputation.

I also had issues with ballistics and reps for ballistics giving me two different answers about the terminal +/- configuration.

I have Ballistic battery the 16cell(not the 16cell HD)
starts it quicker than the old lead battery even when the lead was newer. no problems with it. alot of power from it for easier starts .

the 12cell was the biggest in cranking amp that they made until last year sometime and the 12 cell is what they used to reccomend for all big V-Twins and high compression engine bikes but now they have the 16cell and the 16 cell HD with more amps and so this is what they reccomend.
the ballistic and the other Lithium Iron Phosphate (High Power Lithium Ion Cell, Phosphate-Based) batteries are a different breed of batteries and are not for everyone , and may not be the best for you if you have always on accessories like alarm. do some research on before you buy it they are alot smaller and lighter than the lead acid batteries andyour battery holder may need a small modification to help hold it in place.


You should not allow the battery to discharge below 9.0Volts, as this can damage the cells. If the battery is drained below 6.0Volts then the battery is considered to be discharged beyond its capacity

was the ballistic battery a new battery that the shop had not not drained below 9.0V or messed with in any way,first try to take it back to the shop where bought it from and exchange it for another! new technology makes people want to try and test it out and do stupid things to it and then just stick it back on the shelf. next question would be; did you hook it up with the correct polarity ( maybe check the battery polarity to with a ampmeter to make sure its correct too), next??- have you made any mods to electrical system or have anything attached directly to the battery like a alarm, gps, radar?? are all the grounds tight with good connections??

• Do not charge a Ballistic Performance Component Battery above 14.4 Volts. This will damage the battery.
•Do not charge with an automatic charger in desulfication mode.
• Do not allow the battery to be drained below 9.0V, this will damage the cells. If your powersports vehicle has a parasitic draw like an alarm of similar devices, disconnect the battery when not in use. If the battery is allowed to be drained below 9.0V, it may not recharge to its maximum capacity. If the battery does become discharged, recharge immediately.

• Do not attempt to charge a Ballistic Performance Component Battery that is below 6.0Volts. A Lithium battery below 6.0Volts is considered dead.
• Failure to adhere to these charging specifications or exceeding these limits may cause battery failure and will void any potential warranty claim.
