We bought some rechargeable batteries a few years ago. However, we managed to lose the charger that went with it. :uhh: Now we bought some new rechargeable batteries with a new charger. This one is of a different brand. We still have the old batteries. My dad wants to use the new charger with the old batteries, but I'm worried that this might have some dangers. All the warning labels on the box and the batteries themselves have really made me worried, and I want to get rid of the old batteries. (I don't want to end up blowing up my house just to save a few batteries!) I'm sure many people here know more about rechargeable batteries than my father or I do. What would you advise? Thanks.
