Good Value: my feedback

They have worked OK so far - however, have not used them enough to make a final judgement. The price is right! That's my feedback.

Pros
  • No memory effect means longer battery life and consistent performance
Cons
  • The batteries may not work properly if it’s wet from sweating

Spend the extra money for an investment

They certainly aren’t even close to OEM milwaukeeM12 Batteries ! They will get you through a 20 minJam depending what tool your using then in.

Pros
  • Very pleased with the batteries. Just as good as the brand name ones at a much lower cost!!
Cons
  • May not hold a charge as long as expected

Pros
  • its work good, but some time its loos connected , but using original one work perfect.
Cons
  • The battery may not charge fully

Life expectancy vs cost

After right at 1 year I started getting a flashing light on my charger. This is 1 of 4 batteries. Ordered them about 2 years ago and curiosity got to me, so I thought id try to figure out what caused the failure. This battery was in a very light use tool, Milwaukee M12 temperature gun when it died. Occasionally may have been cycled through a 3/8ths ratchet, but doubtful as the tools never really crossed paths. So it's not as if it was in a high load or use situation. Still not a terrible value…

Pros
  • Longer charge life than older battery technology
Cons
  • The charger may not be able to charge the battery fully

Good replacement battery

So far better than the original battery. Not sure how many cycles they are good for, so far have only recharged 4 or 5 times with no issues. Seems to hold a charge in storage as well as the original.

Pros
  • A great investment for DIY enthusiasts and professionals alike
Cons
  • The battery may not work with all Milwaukee chargers

One battery defective one works so far.

One battery works so far the other one defective out of the box would not charge. Flashing red/ green in the charger Indicates it is defective.

Pros
  • A high-performance 12V battery that is both safe and affordable
Cons
  • The battery may lose power more quickly than older models

Get a couple extras at such an affordable price.

Short term - these charge and run it seems just as good as OEMs. They fit the charger and M12 tools no problems.No issues for fit and finish.For the price, what's not to like. Glad to get and give these a try. Absolutely no regrets so far.

Pros
  • No
Cons
  • Batteries may not work well during high-demand usage

Don't buy from Energup

very poor quality as you can see will only charge to 25%. Energup customer service basically said get over it! Don't buy the junk.

Pros
  • Compatible for 48-11-2411 48-11-2420 48-11-2401 48-11-2402 48-11-2401 12 volt M12 Cordless Tools.
Cons
  • Batteries may stop working after a few months

Measured actual capacity at 2272 mAh

These seem better than some of the other knock off batteries. definitely worth the price. I measured the actual capacity at 2272 Mah. While they didn't reach their advertised 2500, they're still more capacity the the 1500mAh Milwaukee originals for considerably less money.

Pros
  • Tight going in and out. Power is ok. Will probably try another brand next.
Cons
  • Shorter lifespan than advertised

Revainrating 4 out of 5

Working, but won't stay installed.

They both work but they don't exactly "clip in" and or stay on that well. They do slide off. I'll just have to try to rig them to correctly stay in. Yet again, it happens when you buy from off brand companies.

Pros
  • Product looks good. Seems to work ok have not had a chance to put them the the test yet.
Cons
  • May not work with non-Milwaukee power tools

great price ! for my opinion

I have used these for a while now held off on the review to see how they lasted and they are still going strong no issues highly reccomend

Pros
  • Lithium-ion technology means no battery memory, so it can be charged at any time
Cons
  • May not last as long as other Lithium-Ion batteries

Taking your chances

Almost a year later , after maybe 4 or 5 full charge/discharge cycles, one of the battery can not be fully charged . The charger will flash alternating red and green light, indicating damaged battery cells. The other is working OK. So by paying less , you are taking your chance with these knockoff Milwaukee m12 batteries. Have not contacted seller for warranties yet if there is any.

Pros
  • 12.6 ounces
Cons
  • The charger may overheat during use
