After pricing new batteries then getting a price to repack them I had given up pity it is a very handy and usefull drill (I have others).
Eventually bought a 1.7 amp/hour 18 volt Ryobi one+ battery for $48, from the green place, batteries are in same order and stack should be easy? Did someone say they are reverse polarity ? all upside down compared to the Triton, did not take much insulated and ran wires to the correct contacts.
Works well and a lot cheaper than any other way to keep it going ( like $100 lower than the best offer). Still charge with the Triton charger havn't noticed the slight drop in capacity, but then mine weren't much good from the start.
Cheers
