Hercules with DeWalt
The media could not be loaded. If anyone looking to run Hercules 12v on these. This work with no need for soldering in a resistor into your Hercules tool.You will need to shave down the little bump on the battery

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.

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..

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.

No charging device
Works great but no way to charge. Needs a charging unit as well. Wish I knew that before purchasing.
