Replace for Snap on 18V CTB4187 CTB4185 CTB6187 CTB6185 4.0A | Replace for Snap on 18V CT6850 CT6855 Series Impacts Wrench, CDR6850 CDR6855 Series Drills, 18 Volt Cordless Impact Wrench

As good or better than Snapon

Much cheaper than name brand but works just as well

After a very short time charge it works better than I expected and the delivery couldn't have been any quicker. Very next day and no extra was paid

Works great especially since snap on quit making the battery for my impact. The battery has more power than the original snapon battery.

The battery was delivered promptly but completely drained. I put the battery on original snapon charger and red light came up indicating that the battery was bad. Unable to charge at all. Returning this item back with bad review. Now, I am willing to accept that this is just one odd battery and will try with replacement. Whether replacement will be ok or not I will update this review either case. Update. After receiving a replacement battery the symptoms were identical to the first. The battery came completely discharged and attempts to charge on the original snap-on charger were at no avail, only blinking red light telling that the battery was bad. btw, the charger supports nicad and lithium batteries, model ctc620

Excellent replacement battery for snap on tools

I had my original Snap on battery rebuilt but this one has way more power .

Yes it is great and used it for my torque Compact needs
