Still great after 3 years
Bought these batteries because they were significantly cheaper than OEM Craftsman batteries, but was concerned they may not run as long. Tried one battery out for the first time today in my edger/trimmer, and was impressed. Using my old 19.2V edger/trimmer, even when batteries were new, would require 3 fully charged batteries to complete the job. I was able to do everything on one of these 6.0Ah 20v batteries, and there was still charge left. Used the other in my chainsaw to make about 50-60 cuts on small branches that were 2-3", and when I was finished, battery still showed 3 charge lights. I don't know about longevity yet, but initial results are looking good. I'll try to remember to come back and update this review later after I've used the batteries for a while. ---------Update ---------------------------------------------------------- I've had these batteries for 5 months now, and am still impressed. The charge still lasts as long as a 6 Ah battery should, and I've used them quite a few times, so the quality seems to be there. I have quite a bit of trimming to do around the house, and 1 battery is sufficient. They also last a long time in the hedge trimmer and blower. Definitely worth the money. ---------Update ---------------------------------------------------------- So, I've had these batteries for 3 years now, and they are still working great. I numbered the batteries when I got them and try to use battery 1 first and only use 2 when 1 is dead. I can't tell a difference between them still, and battery 1 has a lot more charge cycles on it now. Both are still working equally as well as the OEM Craftsman batteries. I can still blow off my driveway and street in front of house, then do all my trimming, on a single battery charge. When I use it one in chainsaw or angle grinder, I normally need both batteries, but they are a lot heavier power draw. I've put in my Craftsman battery a few times over the years, just to see how long it lasts compared to these, and it's always been very similar. This was definitely a good purchase. ‐------------------- Last update I've been using these batteries for a little over 3 years now, with the majority of the usage being on one battery and the other as a backup. Im sure they have degraded some, but the one most used battery still seems to run about as long as it did new, and about the same as the lesser used battery. I wish I would have measured runtime when they were new so I could give exact reduction in runtime, but I'd be surprised if it's dropped much more than 10%, and the one battery does get used several times each week. I'm still very impressed with these batteries.

Great bang for your buck
Great. Bang for your buck. Absolutely destroys the OEM prices They work as expected with the higher amps. Easily last twice as long as the two amps. Perfect o e m fit. They are a little heavy, but that's 2 beaks expected. Considering their size.

Great product and excellent customer service...
This is a definite 5-star just based off their customer service. I bought the two pack and one battery was completely dead. I have two chargers and neither one of them recognized the dead one. I contacted them and they told me to dispose of the bad one and they'd send me another battery. They kept in constant contact with me and I got the new battery within a week. Both work fine.

After two years.
Bought 2 batteries two years ago. Both batteries were used weekly for home and yard work and a couple of bigger jobs involving multiple charges daily. So no jobsite type daily use. Batteries were not abused or dropped. One still working fine, holds good charge. The other developed an internal loose connection rendering it useless almost exactly two years to the date of purchase. Can't really fault the manufacturer after this long and can't really complain after the two years of Steller performance. I would buy again.

Adequate
I've held off reviewing these for a while. After a few months' use, I feel safe in reporting. They work fine. Their charge is falling off fast than the 5AH Craftsman branded units did, but are still working. At half the price of the branded units, I'm more than happy with their performance. My use case is pretty rough. I have a 2 x 20V branded lawn mower that has a sustained higher amperage draw, that will usually start once, then stay at that usage level for more than 30 to 45 minutes until the low battery warning. If I was using these for my other tools, they'd likely last a lot longer. Despite what I perceive to be a more rapid fall off in performance, these still far exceed the price/value. Qualified Recommend.

on the very last page of the owner's manual...
Used this battery for a lawn shears CMCSS800. The OEM battery (1.5Ah) didn't last maybe 15- 20 minutes, so was looking for something more substantial. The shears' model number didn't match anything on the battery lists. Neither did the battery (CMCB2015/1.5Ah). Searching Amazon did not turn up either (shrug), so was about to give up. R T F M-- all of it! Then, while reading the owner's manual, on the very last page, in a little box, there was a "compatible battery packs and chargers" list. That list suggested that this particular battery would fit my lawn shears and its charger. Had I known there was a compatibility list on the last page of the owner's manual, I could have saved myself an hour of frustration searching online, reading reviews, and otherwise being a numpty. The new battery still had power when I gave up yesterday (too hot, y'all!) and showed a little less than half strength when hooked up to the charger. There is a teeny, tiny little "feature"-- There is a "push here" kind of button/widget on the front of the battery that you can press and illuminate a "how much charge" LED row. On mine, the little widget must be pressed just exactly one certain way. Handed battery to my family and explained how the "show charge" button worked. They followed along as I demonstrated a few times. Then they read the manual, and it still took two or three minutes and several tries to get it to light, because it isn't just "press here" It's more like "press just exactly in this four square micron point with exactly 8.25376 Kg pressure while standing on your left toes and facing due south. However, that isn't even a Planck second of a problem, since we don't really have a need for it. We aren't going to be laboring in the vineyards all that long. Overall, this is a superior little device that does exactly what it is supposed to do with no muss, fuss, nor bother (not like my second wife). Would buy again (not the second wife).

Good price and good company too
I have bunch of 2a batteries. At least 8 I figured I would get one that would last long on a higher pull tool like loppers or chainsaw or clippers. In my mind the name craftsman on the battery doesn’t warrant the extra price. They do t make the batteries themselves anyway. Just get their name out on it. The important thing to me here is that when I charges this all night and was getting 2 of 3 lights as far as charge status I emailed the company. Immediately they sent me another. The new one charged right up. I haven’t used it long term to know about life but am sure it will be fine. It is heavier as to be expected but hardly noticeable on the tool. As for value a 6ah battery is better value than 2ah as far as life and these are much better price than craftsman branded. The only change I might make and it’s not that big, is 4 lights instead of 3 to check life as you go, but that is nitpicking
