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

So far so good. If my opinion changes I'll change my review

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

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.

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.

works

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.

Lacks the red reinforcement ribs on the base as pictured and like the original batteries. It is thin, light-weight plastic and feels light and cheap compared to the original. I wouldn't have complained had it not been misrepresented in the photos.
