I believe it was stored fully charged, but when I took it out after a long time, it either discharged or broke, as there's no response from the power lamp, etc. Therefore, it's being sold as junk. I've lost all the charging cables, etc., so I can't confirm its condition. Please purchase it as junk for repair or parts.
