Make sure it fits your 18v tools.
Take a look at this review.
(Reviewed in the United States on September 13, 2020)

Avoid, does not fit ALL Bosch 18v tools

Bosch makes nice tools, pro to prosumer level but their ecosystem is expensive compared to DeWalt.

Same price I got from Lowe's. Works perfect for my impact and lasts multiple jobs.

Though, I just screw up aluminum track and running wire through house siding.

Normally a 4ah battery would have 10 cells correct? This looks like it has 5. Can somebody clarify if they know?? Thanks!

Bosch and Makita are for the real professionals, Dewalt is ok, Milwaukee is for the wannabes

My 5 year old batteries need to be replaced so I've been looking for a deal to jump on but now I'm wondering if I should wait for the new generation...
