You could, but it would literally take days as it is only 60ma. I got a Tenergy battery pack charger for 24.00 and cut the adaptor and about 18 inches of wire off the Minelab charger, got male/female connectors at Radio Shack, hooked them up to both chargers and the now separate adaptor wire. This charger has a 900ma and 1.8 amp switch. Using the 900 ma switch it takes slightly less than 2 hours to charge the pack. Whatever charger you buy, stay below 1 amp as I was told by a Battery's Plus guy over that amperage the pack may overheat. Also get a charger specifically for battery packs as the circuits charge the packs correctly. Will use the NICAD pack only as backup and only when I get up to about 14 hrs. I went out this AM with 11.67 volts on the NIMH pack and still got 1.5 hrs use on it before it started chirping. Could probably have squeezed another 15-30" out of it W/O too much loss in depth as it was way before the death squeal , but wanted to re hit a little hole with the Infinium. So I think there is plenty of room for error on the battery-life roulette wheel, especially if you monitor the voltage when you hit double digits on usage hours.
