These work well and last a long time!

I get more power and affordable

I bought 2 of these to replace my 10 year old original batteries. I'm not sure they last any longer than the small ones. The best part about them is that they make my flashlight and drill stand up. That alone was worth the money.

I bought 2 of these batteries knowing that they are really 3Ah batteries. The real 6Ah Bosch Battery was out of my budget so I opted for 2x 3Ah and still came up on top by saving 35%. They come charged at about 66% ( 2 out of 3 bars - see pic) 2 batteries means I can run 2 tools without exchanging batteries all the time. The batteries slide in snug and stay clipped in and release fairly easily as well. I can't review longevity as I just got them but if they die sooner I'll update my review. Don't expect a fuel gauge for the price.; you'll know exactly when they start dying and losing battery power.

I've been using these batteries for a fe months now and I have no complaints. They seem to work just as good as the OEM brand name ones. Of course, I don't really have a way of testing that for sure, but so far they've done everything I've asked them too. I'll never buy a brand name battery again.

Even though this battery is fully charged and fits properly it will not power up the tool, whereas a OEM Bosch battery will. One of the sensor tabs does not read the same as the OEM battery and tells the tool there is something wrong. Do not buy this battery if you have this model sander. BOSCH GEX12V-5N

Just got it well see how it last.

I’ve purchased 4. They don’t last longer than the original batteries, so the mAh rating is BS. On one of four, the clip that locks it into the tool was flimsy and broke within the first week.
