    • Smoking deal!!
I love my small 12 volt DeWalts, they have really taken a beating and still work great. Shocking how much replacement batteries cost though, huh? These are, near as I can tell really 4 amp batteries. Let me put it this way, I ran my car starter motor with them. Yes, the 6 awg wires caught fire, and yeah it was exciting, but the battery didn't heat up, and it was just starting to lose power as the fire broke out. I tried to use a fat resistor, but that nearly set tge bench on fire. After clamping the resistor to a big piece of aluminum as a heat sink, the battery voltage refused to drop and I popped the resistor. DeWalt wants $50 for one 1200mAh battery, I got 2 4000mAh batteries, for half that. Excellent value! In actual use and not shenanigans, I have yet to run one down.. ... show more

    • Great batteries for the price
I have multiple Mac/Dewalt 12v tools. I was starting to think that they just weren't doing the job anymore. Then I realized that maybe my Batteries were just old and worn out. I ordered these because they were cheap enough to test my theory. Well I am completely blown away, these new batteries run my tool way better than the original ones. They are stronger and hold a charge longer. Time will tell how long then last but for the price even of they only last a year or two they are definitely worth the cheap price tag. Awesome batteries ... show more

    • Perfect fit
As your batteries start to fail, this is a GREAT alternative to OEM. Half the price, and actually better capacity.

    • They work great and seem to be stronger than the original dewalt batteries
I was a little hesitant getting these as there not the dewalt name brand however they work great and the extra battery life is really nice when using it in the little dewalt flex head flashlight, i can usually run it most of the day without having to recharge. They have been dropped while installed in the flashlight multiple times and covered in every car fluid you could imagine and seem to keep coming back for more without any real color fade were as the dewalt one cracked the case of the battery after the first couple drops. update: 08/31/2020 I Have now purchased two more sets of these as the first set after many drops has finally broken the internal battery tab spot welds unfortunately making the packs useless but before the spot welds broke the batteries were still holding on strong. ... show more

    • Good product at a fair price
The batteries looked exactly like what was shown online. They both work well for my impact which was great because the original batteries both had given up holding a charge. This product was worth the price and I would look for other items from the seller if needed.

    • They work
They work. Time will tell how long they last. My old batteries are from 2015 and 2018 (OEM). I had a cold charge error with one until pulled it out and reinserted it in the charger.

    • Read all info before purchasing any product.
It’s Definitely not Dewalt Quality. But they do fit in all my Dewalt tools. I just hope the battery hold up as well as the factory batteries.
