Bosch hits 6.0Ah for 18V Batteries – BAT622


Bosch is the first out of the gate in the US market for 6.0 Ah 18/20V tool batteries.  What does this mean?  It means massive amounts of runtime.  How much runtime? 45% more than a 4.0 Ah.  That is a lot of runtime and will allow the contractor to be more productive on the job.

The packs use the familiar Bosch FatPack setup which is known to run cool and works with all Bosch 18v Lithium Ion tools.  Running cool means extended life.  Check it out via Bosch.


  1. Wasn’t this announced awhile ago. I think Dewalt and Bosch both announced 6.0ah batteries pretty close to each other.

  2. Dan–I haven’t kept up with the newer (longer-lasting) batteries, so is this 6.0 Ah significantly heavier/bulkier than 3.0 or 4.0 batteries? I assume these are good for someone who’s installing drywall or drilling holes all day; they can be a time saver, but carrying extra weight is tiresome. What I’m thinking is that there may be an optimum battery-life-to-weight factor here, where it makes more sense to use two 3.0 or 4.0 Ah batteries in a day, rather than wrestle with one 6.0 Ah. Or has increased battery efficiency brought the weight of the newer batteries down so that it’s not a concern? Thanks.

    • The 6.0Ah is the same size as the 3.0, 4.0, 5.0Ah batteries. Only a fraction heavier than the 5.0Ah battery.
