We examined the viability of new-type charged Q-ball dark matter scenario. Weconsidered the case where the relics can be treated as ordinary ions, to whichwe applied the observational constraint from MICA experiment, where no trail ofheavy ion-like object is observed in $10^9$ years old ancient muscovite mica.We have found that the allowed parameter region exists but is smaller than theneutral Q-ball dark matter case. We have also discussed whether our scenario isactually consistent with Affleck-Dine mechanism.
