Snap on cordless impact battery adapter?

[nickelmore]

I have an older snap on 12 V impact that needs new batteries. This is only for occasional use.

My options are to get the old ones rebuilt for $40.00 each or

buy this adapter https://store.snapon.com/Snap-on-174-Battery-Chargers-Adaptor-Battery-Slide-on-P644498.aspx

and upgrade to the newer style.

Are there any benefits to upgrading the batteries?

No benefit. I have that adapter because I have some of those batteries because my drill is newer.

That adapter is for 18 volt batteries, however a CTB4145 and CTB4147 battery will probably slide on there as they do slide on to CT4410 impacts and CDR4450 drills which are 14.4 volt tools. That's the only possible options with that adapter. You say yours is 12 volt?

I use those with my older Snap-On cordless stuff with the new style batteries and it works good. Only problem, the older impact +adaptor + battery can't fit assembled into the plastic case. I would never again get a battery rebuilt. I had mine done at a Batteries + place, it cost almost as much as a new battery, never really worked 100%, made a hissing noise and finally died. I then bought a new Snap-On 18V battery / the adaptor and have been very happy.

Yes mine is an older 12 volt, I probably bought it in the late early 90's and has served me well. It was rediscovered last year after not being used for probably 15 years or so when I moved out of my shop to home. Surprisingly one of the batteries still took a charge.

I was quoted $40.00 to have it rebuilt and "conditioned"
