Found a Ryobi 9.6v drill...

.. while cleaning out the garage yesterday, must belong to roomies son.
Drill body has developed a bad case of "The Stickies" (as did my GoPro). Picking it up left fingerprints in the plastic. Looks damn near unused & is now unusable as not only would you need latex gloves, but the battery is deader than disco. Put it on the charger, got a red light for a few seconds & that was it.

Rubbing alcohol will take off the sticky rubber.

Are those NiCd batteries still any good? LiOn seem to last a lot longer.

Look on Youtube and see if anyone's done a LiPo conversion on that style of battery pack. They seem to have done a bit with the makita 9.6 volt drills.

i did see a Youtube video on this using a 12v battery w these Makita 9.6 v tools. I got a couple now, but the 4 in saw that is the most interesting. Might be a fun project using those M12 batteries and an adapter. (i have a bunch)

Another video i saw dispenses with any Battery Management System and just uses a small voltmeter to keep track of battery voltage to make sure it doesn't get too low (and dangerous). I'm going to try this with a small Milwaukee 6 1/2 circ saw (NiCd) that i found at a thrift shop for $5. The plan for that one is to adapt to Ridgid 18v Li batteries (already have the adapter & voltmeter)

One idea for these older drills, if you really want to use one, is to gut the battery case and solder in a 12-14 gauge extension cord with spring clips on the other end, which you can connect to any 12V battery.

This is especially handy if you find one of those 9.6V or 12V Makita right-angle drills (very compact head, good for getting into tight spaces) cheap that has a dead battery. Sure, it's not cordless, but if you are working on a car just connect it to the car battery and get to drilling out those broken off exhaust manifold bolts.

No problem running a 9.6V drill on a 12V battery - it will run a bit faster.

Just curious and never tried it but have you tried a newer Ryobi 18v lithium battery. I know the old ones were not lithium batteries but I thought Ryobi batteries were supposed to be backwards compatible but not sure of 9.6v - 18v formats.

Some things are better left un-found. Scrap it and move on.

My wife drug me to an estate sale, while she was in the fancy area i was in the garage. The auction was not well set up so there was still some digging around. I found a makita 4” circular saw that takes the long battery and the charger, no battery so i got it for $5. I bought a new battery off ebay for cheap and a new blade. I was telling a guy at work, he said he had the right angle drill that he didn’t use any more, so he gave it to me.

I had two of those awhile back that I had bought - same sticky mess. I trashed them.
