Sorry to hear about your difficulties. If you can provide some details, perhaps someone can give you advice.

You say the batteries "are no good." What is wrong with them?

Were they "no good" when you bought them? Did they ever work properly? Did you charge them at the recommended voltage and charge rate? Did they work for a while and then fail?

Is there a problem with the chargers as well?

The more info you can provide, the more likely it is that someone will be able to help.
