Are you going to get the old cells back from the refurb? I'd be curious to
see how many gave up the ghost. I've been scrounging cells from dead packs
and have made useful (though not anywhere close to a matched new pack)
batteries for my 2 mak 9.6 drills. The cells from the cheap harbor freight
12 v (drillmaster) work but discharge at a surprisingly quick rate (on the
order of a week). But the packs sometimes are on sale for 5 bucks. Pat
