What happens with most people is that they fly only 2 or 3 flights and then give their batteries a full overnight charge. If you only flew 3 flights and the batteries could have taken you 5 flights, your batteries were not fully used thus giving a full charge means your overcharging your batteries by approx 40%

Doing this constantly causes whats referred to as "Memory". Its actually a change taking place in the cadmium within the cells.

Refresh/recycling/reconditioning removes the chemical change and brings the cells back to normal or near normal. (Batteries do get old) So it greatly depends on how you use your batteries. Cycling on a regular basis during regular use like for summer flying, is good practice. I cycle my batteries once a month (Ni-cads only - no need to cycle NiMh)

Also I use another little trick an old timer showed me. Regular overnight charge is approx 15 hours and your batteries will deliver 5 flights. So for every flight I do, I charge the batteries for 3 hours. Example: I go out and get in 3 flights. I charge 3 flights X 3 hours per flight = 9 hours only! This way I never over charge my cells causing the memory effect thus recycling is not as critical. If you fly 4 or more then give it the full 15 hrs of charging.

I tried to explain this as simply as I could. Hope this helps. For more detailed info go to

another vote for Red's := Best souce of battery info online.

Also, excessive cycling will reduce the life of your pack. I've seen this case all too often when someone first invests in a cycler...

I recycle in the Spring and check all my packs. If one is weak it is used for a non flying purpose. Otherwise I will only do a recycle if I think my capacity is getting short. I use an ESV to check before a flight as you never know when or if you lose a cell in the flight pack. Been there done that.
