18V 5.0Ah Replace for Milwaukee M18 Battery M18B 48-11-1820 48-11-185048-11-1828 48-11-10 Cordless Power Tools 2Packs

I had no idea these were not actual milwalkee batteries. I havent had the chance to compare the duration of these 5.0s with the guys at work yet. I install Solar panels and use an impact to drive 5.5" lags on the roof after drilling and equal number of pilot holes. I hope they keep up. I was a little put off by the bad reviews.My only complaint so far is that one did not attach to my impact smoothly. I had to put my body weight on it to slide in enough to engage and click.Well, either way, scoring 2 batteries for this price is amazine enough. 1 5.0 at home depot is 129$ 2 for 79$ is great. Not to mention that my 2.0 batteries dont last. I can get only 9 lags in before it dies. Im certain these 5.0 will out last my 2.0s so thats a win regardless.Ill post a review after i use them monday.

Bought these batteries a few months back figuring for the price they are worth a shot. And so far they have held up well. One of the front battery indicator stickers is beginning to fall off, and the charge isn't quite as long as a brand new 5.0 but I wasn't expecting it to be going into it. Other than that these batteries have performed very well, and barring any issues I would recommend purchasing them.

As I feared, these batteries are NOT EVEN CLOSE to 5Ah. How these companies get away with selling blatant lies is far beyond me.Pros:-Overall nice construction. Not as nice as an OEM battery, mind you, but probably the best built aftermarket battery I've inspected. Case is Poly Carbonate + ABS-FR(10) instead of just cheesy ABS alone. It is quite rigid and would probably hold up well to impact. It's nice to see they incorporated at least a little fire retardant. The overmold is rubber-ish like the OEM battery, but is very slick and has almost no grip at all. They should have done without it. I can see the rubber just peeling off in short order.-Seem equivalent to OEM in cold performance. After placing both the OEM and Gerit battery in the freezer for 90 minutes (@ ~0 degrees F), both batteries had negligible voltage drop. They were both functional in a tool. I don't have a high power electronic load, so I wasn't able to test the current delivering ability in this cold test, or in general.-Circuit board looks decent. Not to much to say besides the soldering quality looked fine. No conformal coating, though. The battery level indicator seems to function the same as the OEM battery.Cons:-THESE BATTERIES ARE NOT 5000mAh! That is a complete lie. In fact, they're not even 4Ah! Both batteries, after repeated tests, put out 3.4Ah. What a fricken joke! I have two OEM 4Ah batteries that both put out 3.8Ah (Well within reason given they're a couple years old). These Gerit batteries aren't even near their capacity new, and will get worse as time goes on. After a year, you might only be getting 3.2Ah, or less.-Random cells used. Ok, maybe not random, but even according to their own description, they can be various branded cells. I couldn't see the exact model the ones in my pack, unfortunately. If you look at the pic of the cells in my battery, at lease one looks slightly different. I'm beginning to think they use whatever cells fell off the truck. They don't appear to be used at least. This is why they can make a battery for so much cheaper though (and using lower capacity cells than advertised). The only real downside is that my experience, like with cold performance, may not be somebody else's, given they fact they could have a different brand or model of cell. Someone else might end up with more, or God forbid, even less capacity than me.Overall, a good attempt at a sub-par battery. If it weren't for the BS capacity claim, this would be a five star review. Hopefully Gerit Batt will see my review and do their own testing and edit the description or use the proper capacity cells. I feel ripped off, paying $90 for 3.4Ah after-market batteries. The moral of the story, don't trust their description and buy at your own risk.

Ok so I was very skeptical of these aftermarket batteries but for the price I had to try them out. I bought the two pack one for me and one for the guy that works in the bay next to me, we are both mechanics and we use our M18 1/2 drive imoact guns all day on anything from lug nuts to suspension parts to motor mounts and these batteries just don't quit. I can get almost a day and a half out of a full charge. Battery fits pretty tight but I actually like it better since my Milwaukee battery has gotten so loose I lose connection occasionally. I waited a solid month to leave this review, I'm confident now these are good and I will be buying another set.

Like several other reviewers, my experience is that these batteries don't carry their rated charge. In fact, they last only slightly longer than the 2.0 amp Milwaukee M18 batteries I already had. The Milwaukee M18 450 CFM Blower [https://www.amazon.com/Milwaukee-2728-20-FUEL-Blower-Tool/dp/B01LYNG1R5/ref=sr_1_3?ie=UTF8&qid=1524659839&sr=8-3&keywords=milwaukee+blower+m18] is well known for draining batteries quickly, so that was my test base. I get about 1/3 more blower time with the 5.0 amp Gerit battery than I get with the 2.0 amp Milwaukee battery (20 minutes versus 15 minutes). I was expecting to get at least double the run time.Overall, the batteries take a charge and power my tools, but they aren't a bargain in my experience.

Only reason I am only giving this 4 stars is because I haven't owned it long enough to make a full review. So far I am impressed. I have over 20 m18 tools and usually have 10 to 12 batteries. These are the 5.0 large longer runtime batteries. With the 5.0 they produce the power. Great value for the price.
