Rated 3.4 out of 5 by 28 reviewers.
Rated 5.0 out of 5.0 by Fantastic, but buy them fresh and avoid vibration. Some people complain about these batteries being no good to begin with, or not lasting too long. The first thing is, you have to get one that is (ideally) not more than 9 months old or it could be over-depleted and never come to full capacity. Learn how to read Ryobi date codes on all battery and tool packages, eg 0813 is Sept 2013. Secondly, understand that these high tech battery systems have charge computers inside them, called Battery Management Systems or BMS. These little computers are not vibration tolerant, so DO NOT use these lithium batteries on impact drivers, hammer drills, jig saws, or reciprocating saws. For these tools you need the NiCd P-101. Attention Home Depot... the Lithiums are fantastic for most tools but do not discontinue the NiCD batteries! August 19, 2013
Rated 1.0 out of 5.0 by Terrible chinese product Bought Ryobi Cordless Timmer two months ago. Now battery charger wont charge. Charger gets plugged in but does not turn on. Battery life is always 10 mins long. Very disappointed in product. Will never buy this brand again. Just take $90 bucks and flush it down the toilet if you buy this brand. August 2, 2015
Rated 1.0 out of 5.0 by worst grass trimmer ever (ryobi) 1) two batteries in less than one year 2) trimmer line will not release most of the time August 17, 2015
Rated 5.0 out of 5.0 by Electronician is wrong Electronician's statment that they have a charge counter is wrong and since they use solid state circuitry they are immune to vibrations. the only Vibrations that would cause damage would be on the connections. and that's a Spot weld that let go not something based on the electronics I own 2 of these and 5+ p104's and 5+ P103's Why so many? my wife and I use multiple tools at once. when working on our bathroom renovo she was using the drill, hand vac, and bradnailer. While I was manning the Miter saw and helping pull off the old molding and Paint. as well as using a Impact driver for driving screws into a 3/4 Plywood Sub floor section (toilet leaked) there is a Argument that these batteries are not as tough as the older ones. Id Agree. these black packs use the 1300 LG 15 Amp batteries. which gives you 50WH (pack is slightly under rated at 48WH) 4.2v X 1300MAH x 10Batteries= 50.4Wh the older Pack used the tougher 1200 20A Sanyo' Cells rated at 46WH (again underrated) with this pack you will get more run time out of a drill but a HIGH DRAIN device will shorten the packs life this is no doubt a Direct result from the discharge rate 15amps vs 20amps of the older batteries. How much you ask? well... I have a black 105 pack that's Dated 2012 and a older 104 that's dated 2008 the older abused 104 spools up the miter in a hot second. while my black pack takes another. Also if I jam up the 104 while cutting. it puts up a good fight before the circuity cuts it off. the 105? cuts off when you get the low "whirrrr" from the saw. Granted Ryobi's 7" miter is not really up to the task of cutting harwood 8" planks. but I make it do it anways. I have batteries from 2007 through 2013 and I treat all of them well. in fact so much so that Ive keep adding more with tool purchases yet ive not had to throw one away yet.. The key to making them last is to treat them well charge them and don't let them sit dead for too long, store them inside (not in the tool) since too cold or too hot (garage) shortens their Life by alot January 10, 2014
Rated 1.0 out of 5.0 by Lasted 1 Year Worked great, until it didn't. Had it one year and now it won't charge. April 25, 2014
Rated 5.0 out of 5.0 by New Life For Older Tools The newer batteries brought new life to my older Ryobi cordless power tools. May 26, 2015
Rated 3.0 out of 5.0 by Good battery - but still not 2 times as long as the standard battery Need another battery and I hoped the hi-capacity would get me twice the run time. It did not. Lasts somewhat longer than a standard lithium-ion battery does, but not twice the run time. figure 1/3 to 1/2 again the normal run time. I hoped for more than I got, but it is still a good battery if you do not charge it in the colder northern air (inside it charges fine). November 4, 2014
Rated 1.0 out of 5.0 by Ryobi Battery P105 unreliable The battery didn't last more than 4 months. I used this battery once a week for the ryobi edger. September 24, 2013
