Battery Pack for SNAP ON 14.4V B CTB4145 CTB4147 3.0Ah Impact Drill with Top End

I replaced an aging battery with this pack and it worked simply. You just need a Torx screwdriver and swap the old pack with this one. I see no loss in torque - charging is quick and seamless.

Fit was perfect slid the old out put it back together and thre it on the charger no surprises

New battery for the price of repaired battery

Fits like a glove. Would give a better rating but one tab came bent. Straighten it out easy. It also came charged

Fit my 14.4 volt CT4410 Snap-on 3/8 drive impact perfectly, will buy a second as a backup!

So far, this replacement cell pack has been up to the task. Swapping with old cells took less than 5 minutes. Charge time is quick, capacity, and run time are better than expected. Much cheaper than the tool truck replacement alternatives.

My Snap On 3/8" impact is now "obsolete" which is like saying useless. I don't really need it too often, but there are times running an airline is either inconvenient or impossible. Both of my original batteries are not holding any charge at all and are considered obsolete by Snap On soooo I figured I'd try this replacement vs. throwing away my very expensive tool in disgust. Package arrived early actually and 10 minutes later I had a fully functional impact gun. Charged it up in my existing charger and if it has an acceptable runtime I intend to buy an additional battery pack so I can use both of my batteries. Time will tell, but so far very happy.

Worked for a little while.... now they charge fully but lose charge in a day......junk
