【Upgrade】 6.0Ah Replace Battery for Bosch 12V Battery BAT414 Compatible with Dremel 12V 8240 N-5 Tools and Chargers for Bosch 12 Volt Battery BAT420 GBA12V30 BAT411 BAT411A BAT412 BAT413

I’m a mechanic at a custom shop in Central Texas. I use these batteries on my impact driver and small drill every day. They work great and have a great battery life.

Logged about 40hrs use so far...lasts 3x longer than smaller stock battery. Good fit on tool and charger.

Fits fine , power is good ,waiting to see how long it holds charge.

This works with most but not all of my Bosch 12v tools: It works with my drills (Both the Chameleon / Flexiclick drill/driver and my 12v hammer drill, both brushless), oscillating tool, rotary tool (Bosch brand dremel, an older one labeled as 10.8v which FYI is exactly the same voltage), and my new 3" mini angle grinder. It does NOT work with the Bosch 12v die grinder I just got. Not a hint of life with this battery. I have no idea why, I can't see any physical difference in the electrical contacts, or battery shape or size that would prevent contact, and I looked very closely. I even tested all five contacts on this and a genuine Bosch battery with a multimeter, and they tested the same. Perhaps there is some sort of electronic protection on certain Bosch tools to prevent non-OEM batteries from working, I don't know. So anyway, I can confirm that this battery will work with Bosch drills, and most Bosch 12v tools, but not all. As for charge capacity and lifespan, I haven't tested that yet, I'll come back and update this review once I've used it enough to share something useful. I would be surprised if it actually has anywhere near 6 amp hours as advertised, but for $15, I'll be happy if has half that.

Fit my fifteen year old Bosch tools and chargers fine, charged properly and operates great, time will tell how long they hold up to daily use.

I love this Battery Pak. I used it in all my Bosch 12v cordless tools. It keeps its charge far longer then the battery the tools are designed for and it allows you to stand them up for safe storage.

This is a decent battery for sure, but it's not the same quality as OEM; no way. And of course I realized that would be the case. I think that this - and generic batteries in general - tend to run through their power faster, especially at high draw applications. So my anecdotal evidence tells me that you'll get a fuller "6Ahr" out of this thing using it on a flashlight than you will on a drill under heavy load. It is sort of cool, though, that you can make some of your tools stand up with this (and on other tools, that is for sure a hinderance). Fits nicely on both my very old Bosch flashlight and on my newer, super-bright LED model.

This fit perfectly. I still haven't run it out of power yet. Design lets you stand the tool upright which is a plus. I will be using this as the replacement for all future batteries.

Dura mucho la batería salieron muy buenas compré 2 no dudaría en comprar más baterías de este tipo y marca 100% recomendables
