The makita 9.6 drill I have from 85 is still made , stick packs are
still sold, even my original 1985 pack still works, so I bought a second
drill kit. My Ryobi pack did not last 6 months. Makita uses Sanyo cells,
the best, Ryobi uses chinese junk. By a Makita, Milwaukee, if you need
serious work out of your tools and no battery obsolesance.
