This Milwaukee M12 battery replacement seems to be of excellent quality and works well. I’ve been using it on my drill-driver for several days and it’s still at full charge. The fit and finish are identical to the OEM product, but at a fraction of the OEM price. If anything, this battery fits my Milwaukee M12 drill better than the original and is easier to install and remove. It helps make the M12 line of tools more affordable and I highly recommend this battery!

This has to be the very best aftermarket replacement I have ordered/purchased for my Milwaukee M12 tools.This battery is large, with it living up to the 6.5 Ah rating and easily outlasting what I thought were my large 5.0 Ah M12 batteries. This battery routinely lasts a full day with intermittent use in my ratchet, small impact driver, and small drill. What a difference a few amp hours can make!No issues at all with recharging on both a Milwaukee brand charger and an aftermarket charger. The fit in the tools is just as precise as the Milwaukee brand batteries.As far as I can tell, this has to be one of the best aftermarket options I have for the M12 line of Milwaukee tools. You really should give it a try because at this price point, you can't go wrong.

I don't see how every other "reviewer" didn't test or catch the fact that this battery pack is an outright lie. I ran this battery against my regular "XC" battery pack and guess what...it lasted the same amount of time as the "XC" from Milwaukee. Not the XC 4.0, or 5.0 high output or even the 6.0ah that's offered now. It lasted the same as a regular old 3.0ah. That's FAR from the 6.5ah claim that's all over this listing!Now I assumed that I wouldn't get 6.5ah from this battery, however, I thought I'd at least see 4ah, maybe 5ah if I was lucky. So this is just another china-clone with big numbers slapped on the side to lure in unsuspecting / uneducated buyers. Don't be one of those buyers. Also, upon taking this apart for further inspection, there is NO battery over-current protection built in (no surprise there) to protect this battery pack from being discharged too low and thus damaging / ruining the cells inside. Not to mention possible damage to your tool as well.Does it work with Milwaukee M12 tools? Yes.Does it last? Yes, for 3ah run time, nowhere near 6.5ahWill it hold up like a OEM battery pack? Probably not.Will it be a waste of money and you should've just bought the Milwaukee brand instead? (buy once, cry once) Absolutely.I'm saying this and I received this as a FREE item to review via the Vine program. However, I tested this so you don't have to waste your money on a big fat China lie (again).If you absolutely NEED a battery and can't get an OEM, then this is for you. But be warned, you're not getting what you paid for based on the claim of this listing and you could very well damage this battery or tool.

I ordered this ‘Lizone 6.5Ah 12V Battery Replacement for Milwaukee 12V Battery - Compatible with Milwaukee M12’ just to keep on hand as a spare battery for my Milwaukee M12 tool set. The OEM batteries are so expensive that this one offered a economical alternative.This battery fits my M12 tools perfectly. I like the fact it has a wider stance on the bottom than the OEM batteries do. It allows you to set the tools down upright whixh I really like.This ‘Lizone 6.5Ah 12V Battery Replacement for Milwaukee 12V Battery - Compatible with Milwaukee M12’ has decent power and runtime…but not quite on par with the OEM ones in my opinion. It charges reasonably quickly as well.My big complaint about this ‘Lizone 6.5Ah 12V Battery Replacement for Milwaukee 12V Battery - Compatible with Milwaukee M12’ is that is doesn’t have an integrated charge indicator built like a number of my other generic batteries do. That’s a super handy feature to have on a battery and pretty essential for me.All in all, this ‘Lizone 6.5Ah 12V Battery Replacement for Milwaukee 12V Battery - Compatible with Milwaukee M12’ is a good value even without the charge indicator built in. It charges relatively quickly…has good power and runtime…and has a nice vase on it to keep your tools upright. And it is available at a good price…about half what you’d pay for an OEM battery.

NOT ELECTRICAL SAFETY LISTED AND LABELED – NO WAY I AM I USING THESE IN MY HOMEI am so disappointed receiving these dangerous NOT Safe Milwaukee type 12 volt Lithium batteries.– NOT Family Safe – NO electrical safety testing certification – I returned itSafety First -The most important thing is that these NOT Safe Milwaukee type 12 volt Lithium batteries ARE NOT SAFE to use in your home. The NOT Safe Milwaukee type 12 volt Lithium batteries DO NOT have an electrical safety certification label.- If these Milwaukee type 12 volt Lithium batteries were safe and high quality, then certainly the manufacturer would have submitted this product to one of the independent electrical safety testing laboratories for electrical safety testing, certification, and labeling. I wonder why the manufacturer did not have this product safety tested. I am NOT going to use this product. You should not use this product. Why would you use it when you can buy proven safe electrical safety tested certified products from all over Amazon?- I am NOT using these dangerous NOT Safe Milwaukee type 12 volt Lithium batteries. I returned them. I often buy light fixtures, or electrical products, or Lithium Ion Batteries on Amazon where the website description does not bother to mention the electrical safety testing certification. I just assume that I will receive a product that is safe for my family. I am always surprised and dismayed when the light fixture, or electrical product, or Lithium Battery DOES NOT have an electrical safety test certification label.- I only recharge Lithium Ion batteries in a charger that has an electrical safety test certification label. A Lithium Ion Battery Charger is a very complicated device that has a semiconductor computer brain chip and sensors that constantly monitor battery charging parameters. Those charging parameters include starting charge and ending charge voltage and current, battery temperature, and has Over Voltage protection; Over Current protection; and Over Temperature Protection. The computer brain also charges the battery via a very complicated routine that is constantly monitored and accordingly altered to protect the rechargeable battery. I am sure that many of the Lithium Ion battery fires are not always the fault of a defective battery, but instead the fault of improper charging.- For my moral values, to keep my family safe, to keep other families safe, for my liability insurance requirements, and to keep my home owner’s insurance valid, I only use or install ETL or UL or CSA, or TUV, or Triangle VDE, or Diamond VSE, or BACL electrical safety certified and labeled electrical products in my own home and in other people’s homes or businesses. These electrical safety certifications are provided by third party electrical product safety testing laboratories that are independent from the manufacturer.- The CE label IS NOT a certification of independent laboratory electrical safety testing.

If a product has passed the strict electrical safety testing by these laboratories then it must show that safety certification label on the product itself. There is NO such electrical safety certification label anywhere on these NOT Safe Milwaukee type 12 volt Lithium batteries.- Before installing an electrical device, the first thing an electrician does is to check for the electrical safety testing Laboratory Label Logo and Certification Listing number.- Ask your city’s electrical inspector if they will approve use of NON-safety certified and labeled electrical devices in your home. Then ask your professional licensed electrician if they will install UN-certified electrical devices. Then ask your home owner’s insurance agent if your home owner’s insurance will be valid if you install such NON-safety labeled electrical products. Of course, your home owner’s insurance agent will not inspect your home’s electric appliances until AFTER the fire, or electrocution, so that the insurance claim can be denied.
