【Upgrade】 2 Pack CaliHutt 18V 6.0Ah Replacement Battery for Ryobi ONE+ Plus 18V Battery High Capacity 18V Lithium-Ion Battery P102 P104 P105 P106 P108 P107 P109 for Cordless Power Tools

For an Original battery it's like 3X the price. I was shock to find this at a low cost. My old battery is giving out way sooner so I thought I replace it before it dies on me. This one last like a brand new Original battery, fits my weed-waker perfectly.

Apparently I bought this a while back as a replacement for my Ryobi weed whacker (Hank Hill voice). Okay, my Ryobi line trimmer (Urkel voice). It holds a charge, is more powerful than my original Ryobi batteries and is still working. It lasts about half an hour at full strength, then diminishes for about another half an hour, which is fine because I don't have an acre to whack.

Got this battery brought one before. I was so impressed with it I had to buy another one. Now I’m able to use my drills and impacts with waiting for my battery to charge. Would recommend getting the two batteries so that you have extra batteries without having to worry about it it’s charger.

These are good battery replacements for the real thing and cost effective. My Ryobi 4.0AH batteries were beginning to age (I thought) so I increased my stock of them with two of these. They are near identical physically. Although they claimed to be 6.0Ah, after using them a few times I finally connected them to my battery capacity tester. They start off with 19.5v, which is the same starting voltage as my other Ryobi batteries and my Dewalt 20v batteries. I guess its all in the marketing as to what voltage they claim. I set an end test voltage of 16.0v on my capacity tester, and a current draw of 1A. Most tool batteries get hit pretty hard for power demand, so 1A is a relatively low current draw versus how they actually get used. It is know physics that the capacity of a battery actually drops off at higher current loads, so this was a 'kind' test. Having fully charged a battery, I attached it to the capacity tester, and every battery read ~ 19.5v as a starting voltage. Turning on the tester, it drawers 1A, and monitors the battery voltage and the elapsed time. The battery voltage of lithium technology remains pretty stable for most of it's discharge cycle, and drops off rapidly when it is almost fully discharged. I set up the tester to end the test when the battery voltage dropped to 16.0v, where you can then take the reading of the Amp-Hours capacity of the battery under test. I first tested two of my Ryobi batteries that are quite well used. One showed an Amp-Hour capacity of 3.2. The second achieved 3.5Ah. Ryobi claim these are 4.0Ah batteries, and they may have been when they were new. I then tested these 6.0Ah batteries, and one to be 3.2Ah and the second to be 3.1Ah. They had only been cycled a few times in tools, so I was expecting close to the 6.0Ah claim. The ones I received do not meet a 6.0Ah rating, in fact they are only just over 50% of the claim. However, they are the same physical size of my 4.0Ah Ryobi batteries, so I would say they are nearly as good as the original product. Not better, but as good, so I am quite happy to recommend them. Just don't expect they will last longer in the tool you use them in.

Battery does not last quite as long as the Ryobi, but very close. Only half the price, so I am very happy with this battery

Has already died in outdoor use when real Ryobi Milwaukee or DeWalt will hold up. Hopefully returning. Compatible yes but battery life is good until outdoor use happens and it's a little lite for 6 am and it's size is a little off .

So glad I got a larger capacity battery. Last much longer than the battery that came with it. I can now use the weed trimmer and still have enough charge left over to use the blower to clean up all the trimmings. I used to have to recharge between, no more.

Sure looks a lot like the OEM version. And works like it, too. Takes a charge, holds a charge, runs a long time. Just to be safe, I don't let these "live" on the charger 24/7, but I don't do that with OEMs either.
