It's funny cuz I typed in three words and found 15 vids of how to do it, and yes for nimh batteries. I'm also not a dick I happen to be a very helpful and easy going person, But as usual ppl need to be spoon fed on this forum... Go figure. A wee bit more then 15 minutes of research may be required, also I'd have steered you in right direction if you had some humility too.
Example: I tried you tube and I was unable to find a video that pertained to my particular battery, what can you suggest I try to search?
Now this shows that your not expecting to be handed an answer but are looking for guidance in the right direction.
It seems more and more kids today have a hard time researching the easiest of things.
