I’m not impressed with these batteries. Had small project with brad nail gun, about 2 hours, compressor kicked in about 4-5 times from initial start up, both batteries had been fully charged, first time used since I only got the unit for Christmas. Maybe from sitting or lack of use, wouldn’t want to be to far from a power source if this is what I can expect from these so called 6 hour batteries.
This battery provides plenty of power and it last long. However, I bought this as an upgrade to the original battery pack that came with the impact gun because that battery case started to crack within 3 months of use. To my surprise this heavy duty battery pack also started cracking after about 3 months of use also, and not because it was dropped or mishandled but because of vibration from using it when working on cars So disappointed in the build quality that I wouldn’t even consider buying another one because I feel that the same thing will happen again. And these batteries are not cheap. Mechanics that are thinking of getting this just beware of this issue.
