Topic tags/keywords: question drill-driver

I have a Ryobi -ONE set I have had a little over a year now. Run one of the batteries down, put on change to come back later to a light that said it was defective. I am a bit frustrated these aren’t cheap batteries to replace. I know I did not buy DeWalt but really. Am I just a rare case, is it the lithium batteries or do I want to look at going a different route for my cordless future?

I have had a Ryobi One drill for several years. Mine was NiCad when new? Just replaced those this spring after nearly 7 years. New ones are lithium. Really liking the new ones thus far but too soon to tell longevity. My only dislike is that they will overload out if the drill is loaded too much. When I made the replacement on the batteries, I bought them in kit form as an impact tool, 2 batteries and charger. Thought the deal was a little easier to swallow that way. I have had DeWalt, B&D, and Ryobi and as a hobbyist, I have been most satisfied with Ryobi dollar for dollar. Just my 2cents.

Thats why I refuse to give up my old Makitas and their NiCD batteries.. a new NiCD battery for them costs under $20 (and has almost twice the AH rating as the originals). They also have a much wider operating temperature range (well below freezing, which NiMH and Lithium can’t do), can handle heat much better without permenant damage, are not as sensitive to charging temperatures, and have almost twice the charge/discharge cycle life (approx: 500+ cycles compared to about 300+ for NiMH and Lithium). About the only advantage I see with Lithium (and to a lesser extent, NiMH) batteries is a slighter longer life between charges due to their greater energy density and a smaller self-discharge rate when not being used.


PS: If you are considering changing a NiCD device to Lithium, make sure your charger can handle them.. they are very temperature sensitive and most older NiCD chargers are not compatable with them.

In the past I thought Ryobi offered a lot of cordless tool
for the money and I used them. The batteries kind of
always sucked but you used to be able to buy a pair
of 18v NiCads for $40 so the suckage was tolerable.
Later they put the price up a lot higher and introduced
the Lithium format but I’ve seen a lot of complaints
about Ryobi Li-on life.

If you like Ryobi and want to stick with the one-Plus
format, you can get Ni-Cad batteries rebuilt and
with superior modern cells. Ni-Cad battery technology
is probably still improving and today’s cells are better
than the ones that were around in Ni-Cad’s heyday.

In fact, lifespan is a concern with all lithium drill batteries.
They work great as long as they work, but…

quoted from me:

“No matter what type of rechargeable battery you are using, its enemy is heat. Lithium batteries have a protective circuit in them that shuts them down, permanently, if the circuit “decides” the battery has developed a defect. That’s because defective lithium batteries can explode. I’ve researched this matter quite a lot and have only recently adopted lithium power tools, choosing to stay with Ni-Cads up until a couple of years ago. The best maintenance practice to prolong the life of any cordless power tool battery is to let the pack cool thoroughly before recharging it. This will hopefully prevent your lithium battery safety circuit from tripping prematurely and rendering the battery useless. The larger the battery pack the more heat gets built up inside it so smaller packs will cool off faster. Ni-Cads and Ni-Mh batteries don’t shut down the way lithium packs will, but putting a hot battery on the charger will still cook them and diminish their lives. I certainly cooked plenty of Ni-Cad batteries before I learned this.”

P.S. I like the 12v lithium format. I have a Bosch drill
and while it lacks a 1/2” chuck the batteries aren’t
too expensive and they aren’t stacked in the pack
in such a way that they take a long time to cool.

Even better, I consider the latest generation of
Li-on tools to be mature iterations so you likely
won’t see manufacturers abandoning the newest
12v and 18v lithium formats any time soon. Battery
prices seem to be dropping too.

There are still Makita Ni-Cad drills operating with those
long handles and the reason is the batteries cool
pretty quick with that old 20-plus year old format
so they don’t get cooked by careless “hot charging”.

Well, whatever you do, DON’T go to Batteries Plus to have them rebuilt!

The work was shabby, I constantly had to take them back for connection problems, and I SWEAR the dang things DIED AGAIN within a month of the one year warranty expiring.

I’ll try somewhere ELSE next time. >:(

Ridgid cordless tools sold though Home Depot have a lifetime battery replacement warranty. If the batteries die, they replace them, free. Somehow I’m sure there’s a shipping charge, but that’s peanuts compared to a pair of new batteries at $120 for their 4 AH batteries.

You have to register them online and send in the receipt within 90 days, and you’re set for life. The warranty does not transfer to a new owner if the tool is transferred.

I forgot to register my ridgid cordless tool set (recip saw, hammer drill, cutoff saw, flashlight, 2 batteries and a charger) and now I’m kicking myself. The batteries still hold and keep a decent charge, but they are definitely showing their age and do not seem to last quite as long as they used to. I bought the set in 2008 (or 2009?) so for 5-6 years of light-duty work I think I have gotten a good run from them (and they are still usable for projects). The batteries are 24 volt Lithium, they don’t make them anymore. The only good thing is that the current batteries riodgid sells will work with my tool set. I won’t speak to the current generation of lithium batteries since I don’t have any 1st hand experience with them.

I’m taking a look at a drill set I linked above which comes with an impact driver, a hammer drill, and two 4.0 ah batteries which are compatible with my current set. It’ll cost less than buying two 4 AH batteries & a Charger. I’ll be sure to register the set this time.

I only have a lithium battery on my Dremel tool and while it has a “fuel gauge” on it, it’s still frustrating getting little warning before the battery turns itself off. Most of my cordless stuff is 14.4V and 18V Milwaukee with the old NiCad batteries and now they’re starting to drop like flies. The tools themselves are in excellent shape and I have no desire to abandon them just for lack of available batteries. I haven’t tried Interstate batteries, but some locations will rebuild NiCad and for far less $$ than buying the few remaining OEM offerings.

I have a Ryobi 18v drill and impact driver. They came with lithium batteries, the high capacity ones, as that was all they offered in the beginning. I have used these regularly (though not constantly) for 4 or 5 years now, with nary a whimper from them.

The only way to get the batteries reasonably is to buy them as part of a kit. I paid $99 for mine, which was the price for 2 batteries alone, so it’s as if the tools were free. You have to keep an eye out for specials.

I used to have Makita 12v nicads, but they eventually gave up the ghost, and wouldn’t take or hold a charge anymore. I considered having them rebuilt, but decided against that.

I used to hate the fact that lithium batteries clocked out quick, like always at the last screw or hole to be drilled. With NiCad you could always pry that last chore out of the battery.
But I have to admit, my lithium Rigid little 12V drills, with the battery in handle, (I own three of them, all identical), have given me two years of faultless service. They each came with two batteries, so I keep the three out of use batteries in a row. The last one charged goes to the back of the line and comes forward as I need it. I often have two or three things chucked up at a time to shorten my assembly times. My old Milwaukee and Porter Cable, I use them so little now that I often find that the NiCads are dead and need to be charged, just from sitting.

And I follow religiously the old adage, Run, Charge, Rest. Never let a rundown battery sit around. Charge it then let it rest.

A word on Lithium batteries; I have had a Dewalt cordless with Lithium batteries for the last 6 years and have replaced both batteries once. One thing I have noticed about them is if you do a lot of drilling all at once and kill the battery, you have to let them rest a bit before recharging. If I immediately put the battery I just killed on the charger, the charger would blink furiously at me telling me to replace the battery. Waiting ~5-10 minutes and reinserting the battery it charges fine. I’m not sure what is going on with the chemistry in the battery under that scenario. Just an FYI.

I’ve been very please with the Ryobi drill I purchased. I wired and entire 5500 sq ft house, drilling every hole with it for every wire. That was 4 years ago. They are still going. Combination of nicd and lith. batteries.

Thanks guys, Just frustrated this stuff is not cheap anymore. Seems money is harder to come by.

So from what I am reading it would be advantageous to let the batteries cool prior to charging. This I did not know.

I have loved these things. Yes took a bit of getting used to the battery dying when its done, thought I had broke my drill the first time.

What is this I am reading about over heat circuit in the batteries. Is this something you could replace and reuse the same battery?

Just a though, I though I ran into the same problem once, but it actually turned out to be the charger. I was ready to recycle what I thought was a bad battery when I put it on a second charger on a whim and it charged and works fine.

Also, if you have to replace them home depot seems to always have a battery deal on black Friday or cyber Monday. Two of the large ones for $99.

My Ryobi charger does the exact same thing if I leave the battery on it for a prolonged period of time, but the battery isn’t actually defective. It’s been doing that since day one. I’ve now had the same battery and charger for 3 years.

You cannot repair a lithium battery with a tripped
safety circuit, nor can a battery shop.
