Up grading from 2.0Ah to 4.0Ah for additional time

These are a Christmas gift but have 5 of the Hart cordless tools and some of the have the 2.0Ah batteries but with the 4.0Ah they can be used for a longer time and they are made to interchange with any of the tools. They seem expensive but are rechargeable so that's a PLUS.

good value purchase

the hart batteries seem to be resilient and durable, they xharge faurly quick and last quite awhile depending on the tool your using, personally the 4ah are probably the best for size and efficiency, the 2ah die pretty quick and really only have a few benefits, being small, lightweight and charge quickly

Didn't know batteries were bad and thought it was tool. When I saw the discount for battery I got them cause they are too expensive and knew there wouldn't be no more price drops. It worked out good cause tools working fine now. I just needed new batteries. I will let you know how long they last and I follow all the manufacturers recommendations.
