Using 18V Battery in 14.4V Snap-On Tools

[Up And Down]

How many people here are using the 18V batteries in their 14.4V Snap-On tools? I have the CT6850 18V 1/2 inch impact and want to get the CT4410 3/8 drive impact, which is 14.4V. I have heard that some people use the 18V batteries in this tool. If this is the case, I will buy the bare tool and only need 1 set of batteries. I am looking for first hand experiences. How is the performance with the 18V battery? Does it spin faster and make more torque? Any reliability or performance issues? Any drawbacks at all? All responses are welcomed and appreciated.

Fine, no, no, none that I see.

Only real difference that I see is a slightly longer battery life with the 18V batteries in the 14.4V tools.

It definitely spins faster with the 18 volt battery on the CT4410A.

You will need to modify the "shoe" on the bottom of your 4410 if you do this. It only takes a minute of so with a sharp knife, chisel or Dremel. It spins quite a bit faster, produces more torque and has not produced a problem so far.

Thanks for the replies so far. How long have you guys been using the 18V on your 4410? How much use does the 4410 get with this battery on it? No issues with burnt out motors or failed switches?

Any more info on my additional questions?

I've been using mine that way for about 6 months now. It doesn't get used very often (just outside the garage) as I usually run air tools but no odd issues so far.

If it does burn out, I will send it in and get it fixed on the flat rate cost. I look at these things like I do the the batteries, they need to be re-built every now and then. In fact I have 2 SO 18V batteries at Batteries Plus right now getting rebuilt.

let me know the cost from batteries plus please sir...

Batteries Plus is a franchise. They might have a location in your area. The one time I checked, they charged about $60 to rebuild an 18 volt battery. Not worth it for us but its an option for your customers.

To replace all of the cells in the pack, my local guy charges $51.99 each plus tax. That includes the labor and the (15) 1.2 volt cells per pack.

I have used a co workers with my 18v batteries and other than it shooting out a shitload of sparks it spins faster and has more power, My distributor almost condones it. Also my interstate battery dealer rebuilt an older snap on 18v battery for me for 49.00 or so.

Can you post a pick of this modification? I have a CT4850 and may pick up the ct4410 if I can use my 18v batteries.

The newer models require no modifications. The 18v batteries slip right on.

 

[dorksterr]

Thanks for the info!!! I may have to pick one up then.

The ones on my truck still need to be modified to accept 18 volt batteries

Mine must be a freak then

What needs to me done to the tool to accept the 18V batteries Chad?

If you look at the bottom of the tool, you'll see a small tab on the shoe that slides into the battery. Grind or cut that off (takes about 10 seconds to do), and you should be able to use both 18v and 14.4 batteries.

I was wondering about this. I'm going to buy a 18v battery and check it out.

 

[bobcatdan]

It is a beast with the 14.4, way faster, more power, enough sparks to put a 4th of July display to shame with the 18 volt. Do it.

Has anyone tried this with the new 18v lithium battery??

 

[gdav211]

anybody?

 

[Creditor]

I have used the 18v lithium battery in my CT4410A with no issues.

 

[FLACOMAN]

Can't imagine the brushes being too happy with that , but something else may die first.
Over -volting permanent magnet motors will slowly degrade them , but it's just a matter of if you kill something else first.

I used to run the 18 volt batteries on my CT30 which was 9.6v
It worked great, until I let the smoke out of it. I'd do it again in a heartbeat though!

 

[gdav211]
