One of the Bloog batteries, I received on Wednesday refuses to be charged on 1 of my chargers but yet it works on my second one. The second one doesn't care what charger it's on. The chargers came from a starter kit from another company and it charges 4 other batteries with no problem. I would think that would probally be a battery issue but just want to see if anyone echos my sentiment. PS you are not going to get the Bloog back unless you pry it out of my hands, I will use the charger that works with it
