Technically, at the charging rate of 3A-hr, your 1700mah should be fully charged by 33.6mins.
-too much heat can damage your batteries during charging
-your aeg won't be damaged by the battery, only the battery will be damaged
-charging a battery would really involve heat, but it depends on the heat the battery takes. If it's too hot, there's a problem.
