PowerextraUpgraded 2 Pcs 10.8V-12V 3000mAh Li-ion Replacement Battery, Compatible with Bosch BAT411 BAT411A BAT412 BAT413 GBA12V30 BAT414, 2 Pack

I was initially concerned about it fitting in my drill as there is a plastic nub or column close to electrodes. This made it really tight fitting, but my tools are pretty new. Upon investigation, that plastic nub is exactly the same on higher capacity Bosch batteries.I am grateful to get both if these high capacity batteries for less than one lower capacity Bosch brand battery.I cannot speak to durability at this time, but for now they are working very well.They are compatible with both of my Bosch tools and with my Bosch charger.

both failed with different problems. first one does not slide in properly to any of my 4 bosch tools. Seems the pins are bent inside so it never bottoms out or makes a connection. Second one does not reliably allow the tool to operate. Oddly when you pull trigger the "spot light" always comes on but about half the time the tool does not operate, except the saw tool which works every time and does not have the light feature. All 4 tools work fine with original bosch batteries. didn't expect issues like this returning for refund.UPDATE: requested return was contacted directly by Powerextra. They sent a return label and immediately shipped out two replacements both fit and work fine. Great customer support could not have asked for more. Sometime things like this happen and a good company will make it right.

fit good

The replaced the originals and have good power and last a reasonable amount of time. Good value if your originals are losing their charge quickly.

They were perfect

So the Bosch oem batteries are overpriced like most brands . These are way cheaper . They look close to oem . They fit my drill and charger . Unfortunately these raise red flags . In the included pic you will see that the electrical contacts on the ones I received were broken off on arrival . 2 out of 4 batteries were defective . Secondly - the batteries safety label has so many spelling and grammar issues that there is doubt that the ROHS and CE certifications are also fake . I do not trust the safety of this product and neither should you . I do not recommend this product.

We have had these batteries for a month or so and so far, they operate all the devices and charge back just fine. THey were reasonably priced and do the job. Hopefully they will last...

Purchased the 2 pack, only one works. After contacting customer service and explaining what exactly was wrong with the second battery, it was suggested by them that possibly I had the wrong battery for my application. Uh, I purchased two batteries and only had a problem with one so... Then they wanted pictures and batch numbers off the battery. Eventually I contacted Amazon and I did receive a replacement battery for the defective one. So far the batteries seem to work ok and hold a charge as well as the originals. Time will tell.
