No. If you are using a genuine battery and an original charger. If you are using a third party "compatible" battery and/or third party charger - anything can happen. Both original camera batteries and chargers have circuitry inside to prevent overcharging. When the charger senses that battery is full, it switches to trickle charging mode, when battery is getting just a little amount of charge routed to it, which helps it stay fully charged and ready to go, but won't harm the battery... So it is perfectly safe to keep the battery in charger for as long as you wish. Many photographers have an extra battery that always sits in a charger, when battery in camera needs replacement, they just switch them. A poorly made battery may fail to properly communicate to the charger that it's full, and a cheap non-genuine charger may not be able to interpret the message from the battery (so to speak), and again, overcharge. This is why it's important to use genuine batteries and chargers, there's a reason why they cost more - of course you're paying a little "brand name" premium, but you're also paying for the electronics inside. If your battery and charger were original ones - then you may have a case for warranty service of either camera, battery or charger, because this should not have happened!
