Replacing all AC Power Tools with Battery Powered Tools.

I do like a good ridgid tool.

I have both Makita and Ryobi battery powered drills and a Ryobi chop saw and skill saw.

I use the Ryobi drill as the power feed on my lathe's compound slide. It is easy to control the speed which makes it ideal for that task.

The Makita drill (9 volt) is at least 30 years old and was used almost daily in my former business. I can't find Ni-cad batteries for it anymore, but there are nickel-metal hydride batteries available, Those batteries, however, don't hold a charge for more than a week or so even when not being used. Other than that, they have plenty of power when freshly charged and deliver more power and for a loner time than the old Ni-cad batteries. If i could find lithium batteries for it, that Makita would likely last another 30 years.

BatteriesPlus can rebuild them.

BatteriesPlus can rebuild them.

I wonder - can they convert them to Lithium ion? I'll have to check it out.

I used Dewalt for years but got tired of having to buy new batteries (it was actually cheaper to buy a new drill with batteries than just buy batteries). I’ve switched to Bauer cordless tools from Harbor Freight, and so far, I’m very happy. I guess the best part is that they’re cheap, so if one does crap out, it’s not to costly to replace.

So I know there is always the possibilty Li-ion batteries can fail when charging and possibly rupture and ignite. I don't know if using a trickle charger over a rapid charger helps lessen this possibility or not. I have one of those Li-ion battery jumpstarters. I had charged with the small wall wort charger that came with it several times leaving it plugged in overnight. The last time I charged it, the batteries swelled up and popped the covers off. Lucky it didn't get worse. From now on, I'm going to do all my recharging on a concrete floor with nothing within 5 feet of the charger.

Even if they could, I would question if your Ni-Cad charger would properly charge them or not. If it did not stop charging even after the Li-ions were full, you will have a big problem on your hands.

Let me tell you about this neat Hart Disk Sanding/Grinder, the the disk retaining device 'special nut" if you are using a cut off disk "much thiner then a grinding disk" you need to reverce the retaining device, Hart does not tell you this can be done, but it's the only way you can lock the cutoff disk to the tool and it works just as good as with the grinding disk.

The problem with Lithium is over charging. Do not quick charge and remove when charged.

Most places will only install Lithium in a Lithium pack. Some techs will put Lithium in, if you ask.

The Ni-Cad charger will charge lithium, but the heat build up could be a problem. Don't leave charger unattended.

Getting a higher capacity Ni-Cad will do the job and reduce the leakage hazard.

how does the tattle tale work? is the info stored in the battery?

In the charger.

I have used Milwaukee cordless for years. Lately I have been buying Ryobi and have had very good luck with them. I heard that Milwaukee bought them but have not been able to confirm that.
