2 Packs BAT609 18V 6000mAh Lithium Battery Replacement for Bosch 18V Battery BAT609 BAT610G BAT618G BAT619 BAT621 BAT620 Cordless Power Tool Battery

I have Bosch Batteries and lots of them. Anywhere from 2000 to 8000. They are also expensive. I purchased two sets of these batteries and use them regularly. They don't last as long as the originals, but they do last long enough. When you buy power tools your really buying the brand of the battery. You stick with the brand due to the investment in batteries. Bosch makes good stuff, sometimes you just need something that works good enough. These meet the need.

Perfect replacement/extra batteries for my Bosch tools. Perfect fit, holds charge well and much cheaper than the Bosch brands for the same or better service. These are higher amp/hour than the originals

Seems ok on life. Not as good as oem, but price makes that tolerable for sure. BUT! It's bigger than the oem battery, so it doesn't fit in the circular saw. Works ok in drills and sawzawl.

Warning: Does not fit well into Bosch 18v oscillating tool. Does not go all the way in so it won't clip in. For all other 18v tools I have, works wonders for 1/3 the price.

I purchased these batteries for my Bosch oscillating saw. They do not fit. The battery is too long and hits the front of the slot for the battery. I do have the Bosch drill and these batteries fit just fine.

Given that my old slim pack batteries that came with my drill and impact driver were about 10 years old and only had a 2aH capacity, I figured I'd give some knock-offs a try before committing to the price tag which comes with the Bosch brand batteries. These batteries are obviously substantially bigger (more cells, thicker profile) which was the only real downfall. Otherwise they run all day and gave my drill set power it hasn't had in a few years. Nice fit, like the originals, nice little battery meter on them which the old ones never had...and snagged them for a fraction of the cost of the OEM batteries. I've had them just a couple of months but with very regular use, they've given me zero issues with crappy run time or charging. Absolutely worth it for drill power demand, but can't speak for how well they hold up on other cordless power tools.

So Far So Good. Started using them today and they work very well.They last almost as long as my Bosch Batteries but cost a lot less.Others have commented that they do not fit the Bosch Circular Saw.The batteries I received (June 2024) fit and function perfectly.Only time will tell if they last as long as Bosch batteries.For the price, they are definitely worth a try.

Good battery and price. I have many Bosch 18v tools and this fits all of them but my vibrating multi-tool.I can confirm fit is good for drill, impact driver, led light, 1.6 gallon shop vac, sawz all, circular saw, universal air inflator, angle grinder.Does not fit vibrating multi-tool.Other reviewers posted pics of the battery case screw tunnel that protrudes at 4 corners. This is what causes the battery to not fit. The manufacturers photos are not of the case they ship.
