fakes? never thought there could be fake batteries, will definitely be more careful next time i find a battery. thanks!

Thanks sfbp for the tip, yet there are no deliveries to Mexico. Avrin, I do clean the batteries every month, so I really don't think that was it (plus even the new ones would not charge), but thanks for the tip.

My first post, please be nice. I've had my MZ-RH910 for a few years now, but only recently did I regret changing from MD to Hi-MD, the reason being the batteries are no longer available (in Mexico); I have not been able to charge the last battery I could get (about 6 months ago), so now I don't even know if my problem is with the built-in battery charger or the batteries. I hate the AA battery case I can use to make the player usable so, is there any advise for testing/charging a new generic battery?
