A123 battery charger near Chicago?
« on: August 13, 2011, 01:06:42 PM »
Hi,

I killed my A123 battery pack today cranking my bike.  I understand these need specific chargers and if you let them sit dead too long they're hard to revive.  Anyone in the chicagoland area have a A123 charger?

I use the standard Battery Tender trickle charger.  Get it on a charge FAST.

Also, just curious--is yours the 4 cell or 8 cell, what bike do you have, and how long did you turn it over?  I've got the 4 cell on my CB400f and have never come close to depleting it (at least that I know of--from what I hear they go full blast till they're gone).  I was worried about taking off the kick starter (had to for the rearsets), but I barely have to even look at the starter button and she fires right up.

You can use any small charger. The recommended rate for a 4 cell pack is 3 amps. Closely monitor the voltage with a meter. As the battery nears full charge, the voltage will start to rise rapidly. Shut off the charger when the battery gets to 14.4 volts. Get some electrons back into that battery, quick!
Don't fix it if it ain't broke!
