Great Fit
Thus works great with my Bosch 18V sander and router. A great price versus MFG. Seems to last just as long as the MFG.

Great value
What great value - works well. Haven’t tested full capacity but definitely sufficient for small tasks around the house no issues!!! Highly recommend for domestic occasional jobs than paying for OEM!

It’s noticeably bigger but seems worth the money
The battery seems to work fine though it is quite a bit larger than the name brand. It is also a little heavier but I don’t really notice the weight when using my tools. All in all it’s a good value for the money. I haven’t had it for long so I can’t speak to longevity.

Work great, I would recommend
I'm using this on a drill and impact driver. No problems. Battery life seems a bit better than the oem 2Ah battery I replaced. Keep in mind this battery is roughly 3/4 inch taller than the 2 Ah bosch battery so if you're needing to work in a really tight spot it could be a problem.

Extra power when you need it.
Always good to have a spare battery when the job is a long one. Perfect replacement.
