    Bought this battery back in December of 2022 and here is is July of 2023 and it is refusing to take a charge. Tried multiple chargers with no luck. Would not advise you to buy it.

    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.

    Not much to say about them, they’re batteries. They were a great price, I get a little over an hour worth of usage out of them on my Bosch cordless sander, and that’s with the 4ah batteries. They do however take a long time to charge which probably has more to do with the charger then the batteries. But I will be ordering another two pack soon. It’s a great deal considering what Lowes is asking for them.
