Bosch Quality
More time. More power=More work gets done! Just realize that this largest version of Bosch's 18 volt batteries will only fit in certain Brushless and/or PROFACTOR tools such as their Leaf Blower and certain Impact Drivers etc etc. But when it fits in the tool, it delivers more energy for more time. A fantastic addition to your Bosch collection!

Really nice battery
Very large 3lbs of lithium-ion bosch power house 👍🏻 I have the new cordless table saw & this works great on it. It won’t fit in the vacuum but if you cut off one small tab that is sticking up (look at another 6.4 amph battery and you can see it) now it will fit in all your tools but vacuum like I said. Works great on the blower/drill/impact/light. So if your in the market & the price is right I got mine for $139.00 I couldn’t say no to that price. It’s a great battery long lasting

Game changer
If you own any BOSCH Profactor tool...just buy the 12ah for all of them. My first saw came with an 8ah...that's a pretty big battery right...wrong. This 12ah makes that 8ah look like a joke on every level. Much longer run time, and the power increase is mindblowing. You won't regret this upgrade.

Like a Bosch should be.
This is the only way to get the job done. I have several high needs tools. Mostly my SDS max. Drilling holes or stripping tile. This will last as long as you. Swap it out with a second on break and it’ll be ready to go by the next break. Doesn’t get any where near as hot as my 8ah’s and last twice as long. Definitely worth the money to make more money.
