looking for a charger

Just bought a yak and it came with a icom icm88 radio but no charger.  I would like to see if the battery is good before I buy a charger, but may just have to suck it up.  Does anyone have a charger for sale or one that I can use just long enough to see if the battery is good?  I am in Salinas CA. 

You could buy a 12v charger should be able to get 1 for $10 or so. I keep one in my car it charges very fast.
