I got this 2000 mAh NiMh battery but I only have the stock charger that came with my radio. it has an output of 80mA, I have another 600 mAh battery that states a 15 hours charge with a 60mA charger, then I'm assuming that to get a full charge on the 2000 mAh battery, I need arround 36 hours of charging with the 80mA charger... am I correct? should I get another charger?
That's too much time but if you charge with that time from a fully discharge battery as long as the charging rate is similar to that, the battery is fine. The rate is less 5% of the capacity. That would not heat up your battery internal resistance instead charger internal resistance compensate when battery is fully charged. That is to make sure the battery is fully charged.
