You can test your charger under load if you have some 10W ceramic resisters, the kind used in thermostats ( they look like a white block with wire leads coming from each end. ) place one end of the resister lead on your negative side of the charging dc barrel plug and the other end of the resister to the negative post of your multimeter. and the other positive post of the multimeter in the middle of the barrel connector. then place your multimeter to read amperage. look at the big square part of the adapter and read the label on the back. it will show the amperage level it can produce, next look at your battery and see its charging amperage draw. compare the draw to the reading on your multimeter.
