I used to use the wall charger overnight until I did some math on my chargers. It would take about 3 days charging to fully charge some of my 2100 mah batteries at the rate the wall charger charged. I use a Triton and other nicd/nimh chargers now and get a full charge. Look into your charge rate and your batteries capacity and figure out how many hours it should take to charge your battery. You might be surprised.
