【Upgrade】3.0Ah Replace Battery for Bosch 12V Battery BAT414 Compatible with Bosch 12V max Lithium-Ion Tools and Chargers for Bosch 12 Volt Battery BAT420 GBA12V30 BAT411 BAT411A BAT412 BAT413

If you own an older PS41 Bosch drill/ driver these batteries plug in the tool and charger with no more resistance than the original batteries. I can't make a prediction on how long they will last but my original batteries were losing their charge fast if I was drilling or driving long screws in thick material . This small drill driver has been a life saver working in tight places especially between flooring joists due to its compact design. It also has a hard drive knocker just like an impact wrench and is really versatile with a add-on right angle drive. Happy to find these replacement batteries AAAA++++

Great price

Takes a bit of force to insert, but works.

This battery charged fine with the Bosch charger and the fit form function works great in Bosch 12volt products. I highly recommend to all needing a replacement 12 volt Bosch battery.

A genuine 12V Max Bosch battery powers a Dremel 8250 just fine. This battery is not the same as the genuine because the dremel does nothing when you try it, even after being charged. Upon testing it, the original Bosch has full battery voltage at all three small terminals, compared to positive. This wanna-be only has voltage at two of the 3 small terminals - the center one and the one beside the large negative terminal. Apparently the dremel uses the small terminal beside the large positive terminal for something, because there is a contact in the tool for it, and the tool does not work with this battery.

Worked perfect for my hand tools

Fits/works great in Bosch 12v drill/impact. Much lower price but higher Ah rating than original. Great deal so far.

The price is the best feature. It's a battery.
