spark batteries in stock

I have a couple of spark batteries that were sitting idle for over a year, and they won't charge again. I read that since they were uncharged for such a long time; the "smart chip" that "protects" the battery, takes is to a point that you can not charge them anymore. Does anyone know a hack on...

firstly, thank you for all the help and advice today, brill forum! Spark Batteries? Is there any model to look for? I've just seen a 'part3' battery and it made me wonder if there were different batteries... Cheers!
