No, just charge them for 2-3 times longer to get them to maximum capacity.

For instance, if your charger is rated at 50mA (I don’t remember) and your batteries \
are rated at 200mAH (note that the batteries are rated as milliamp HOURS) it would, \
theoretically, take 4 hours to charge. The batteries aren’t perfect and you should \
multiply this time by about 1.4, so 5 or 6 hours.

With 600mAH batteries, 600mAH/50mA*1.4 = 16.8 hours.
