Can a charger that was made for 1.2 volt AA batteries charge 3.7 AA batteries?

A rechargeable battery has specific charging procedures. For instance lithium-ion batteries will burst into flames if they are not charged just right. Figure out exactly what kind of batteries you have and go get a charger for that exact type. I never heard of a 3.7 AA battery, but a google search shows that there are in fact 3.7 volt lithium-ion batteries in AA size. Amazon.com has chargers, or any place that sells the batteries.
