THE BEST Batteries On The Market
I date my batteries when I get them. I am still using 2.0ah Bosch batteries I bought in 2012! One is starting to lose it's longevity after TWELVE YEARS of use! These 4.0 batteries run tools forever, at a slightly higher weight than the basic 2.0ah pack. I grab batteries when they are on special and I just got four of these 4ah batteries to run bigger tools like saws and blowers. I have been a Bosch owner for 20+ years and have 17 tools that have run reliably and taken routine abuse.
