Why do my postings in the battery/chargers
section keep getting deleted??

Any classified ad or wanted ad will get deleted as will most personal attacks. Also posts may be moved to a more appropriate area of the forums but in any case whomever did it should have sent you an email.

Those are just some examples of reasons, I dont know in specific about your case.

I think it's pretty obvious, but if you really question why send me a PM and I'll be happy to explain.
