Ridgid drill/driver kit with 2, 2.0AH batteries
#1
I had a 18v Makita Kit, the white and black models, for about a decade, but the batteries became nearly completely worthless in the last 18 months, and 2 new actual Makita batteries cost 80% the cost of a new drill driver kit with new batteries.  Was not going to risk the generic battery replacements.

So, I was using an ancient old Craftsman 9.6v drill, with ~8 feet of 12AWG, to my 18 or 22AH AGM batteries via APP's for any task requiring strength and duration, but the 18Ag AGM battery is 11 Lbs and the cord gets annoying. 
 Gobs of torque and torque for days though.
  The motor could pull as much as 35 amps.  
Its showing its age and abuse, but made the cut in the move, the Makita's didnt. 

So new drill and driver needed.
Basically dedicating to a battery system, although there are now adapters to use one tool's batteries in another brand tool.

I had it narrowed my decision to Dewalt, or Ridgid.
The 20v Dewalt kit was 20$ more and comes with 1.3AH batteries, the Ridgid 18v kit comes with  2.0AH batteries.

Beware of marketing.  In the US, the battery pack can be rated at its full charge voltage, instead of the nominal voltage of the cells within.  In South Africa for instance, Dewalt's battery has to be called 18v, in the USA they call it 20v.  Both ridgid and dewalt use  5, 18650 cells, in series.

Ridgid also has the 'lifetime service agreement', meaning if one registers it properly within 90 days of purchase, they fix it free, for original owner, forever, and dead batteries, replaced for free too whether failed or just worn out and no more capacity.

I thought what other cordless tools that I might like to acquire in the future, and checked out what was available between the two brands. I also checked out additional battery prices, and Ridgid has 2, 4.0 Ah battery deal going,  for 99$, which is far less than Dewalt's offerings, or pretty much any other brand.

So, I Figured I go Ridgid.  I used a Ridgid  contractor's Tablesaw at a friend's workshop, and liked it far more than my Makita contractor's tablesaw.
Another friend had the Ridgid heavy ass iron top workshop tablesaw, and it was almost dreamy to use after the portable models.

I've own a corded Ridgid jigsaw for 6+ years now,  and like its design and function, though I never bothered to register it for the LSA.

I had no experience with cordless Ridgid products

So the Kit arrives 2 days after ordering, via fedex. 
The impact driver's gearbox seems a bit loud and gritty, but had no issues driving 45 3.5 inch screws into old hardened treated lumber.
 The drill's trigger is a bit weird, At first I though it was a delay, but more recently realized the first 1/4 inch of movement illuminates the light, and after that range it responds instantly.  Takes some getting used to  after the instant response of the other drill's triggers, that I am used to.

I don't know why they insist in 6500K+ blueish LEDS. I'd understand if they were super bright, but I find the output a bit lacking and far too blue. 

The batteries are not really a super tight fit in the drill/driver.

The battery charger's wall wart says 18v, 60 watt output,  but voltage has to go as high as 21v to fully charge 5 18650 in series.

I drained the batteries to 1 of 4 bars, down in to the 17.3vDC range, split the wire and used my clampmeter to see how much amperage it allowed the batteries to feed on.  2 amps exactly, lets assume 21 volts, and  42 watts.

Should take about an hour to fully charge a dead battery to full, but I did not drain completely, nor charge until the charger quit, nor use a timer.

My Makita charger was bulky, had a noisy fan for force flow feed the battery, and would draw far more than 40 watts via my PSW inverter IIRC, but was 15 minute charger too.

Anyway,  I don't think the Ridgid has the fit and finish of the Makita's I owned, but I spent more on them 10+ years ago, than the Ridgids 3 weeks ago.
  
My Makita drill developed gearbox issues, and at the end needed new brushes, but with the capacity free batteries and weird intermittent gearbox issue, i just gave up on the drill entirely rather than order 8$ of brushes and install them.

The Ridgid did not come with the handy hooks to hang on a belt, or waist band or pocket, but I ordered some cheap generics.

Been contemplating a leaf/jobsite blower.  Ridgid offers 3.

While comparing the three, I saw that the two ,4.0Ah battery deal for 99$, was now 79$, for the next 5 days. 

Trying hard to not click 'add to cart'.

My dad has a 18v Ryobi leaf blower.
Pretty weak as blowers go, but adequate for his needs.
First 1.5ah 18v battery failed a whike ago, and was in a cabinet.
He bought a single 4.0 ah battery to replace it, still complains about its price.

I took it apart.
5 18650 LG cells in series
4 cells measured 3.6, one cell 1.67v.
They are respected.1500 mah, 22 amp max cdr high drain LG flattop cell.


Used some sidecut plyers to cut then rip off welded tabs, dremeled off the sharpies, and added a solder blob to the + tips filed it to a flat button shape.
Charged them, drained them to low 3 volt range, then re Charged them to full measuring mah accepted via a USB inline powermeter.
All 4 were within 20mah of each other, right near 1200mah.
Far better than any other 18650 cells i have salvaged in the past.

In one.of my high power flashlights, they can maintain peak brightness for 2x as long as my ncr18650b cells which are high capacity cells, not high rate cells.

Also the ryobi battery has a real nice18650 battery caddy inside of it, as one woukd expect on a power tool battery.
Beats having loose cells rolling around.
I have just enough 18650s of adequate health already, but a few introduced into rotation will just have them all cycle less.

Pretty much sums up so much of why the contractor wars over Makitta/milwalki/Dewalt died years ago.

So many yotube creators doing the testing and highlighting. Issues between th e brands and the slowly diminishing differences.

If you don’t make a living with it the return/replace factor for this living in the USA a non issue. Burn out a drill or cap the batteries just dial and replace. Take a 24hr brake and…new shit in your mail box.

My trashed shoulders and small hands love the Dewalt mitymini atom driver. But it ain’t every going to be cracking suspension bolts. But then again never are these shoulders.

Yeah getting locked into the battery systems were a pain but as you point out not an issue anymore. With the repair or replace for life at sub 300 tool where’s the choice? Unless your build outfit just has to have yellow or red colors hanging off your belt. Lol.

Good read. Just sitting in Lufthansa Lounge to board a 10 hour flight to Kazakhstan. Long because of the can’t go over Russia bit and it lands in the capitol city first and then on to my destination. How that qualifies as direct IDK. But that’s what’s it’s called. Front of the bus so I’ll be drunk for most of it. International chapter out.

I was reading abut a dewalt.drill with issues within warranty periox amd to get it warranti3d in the US the owner has to mail it off , AND provide a credit card number which will be charged 89$, and then reimbursed if dewalt determines the failure is their fault, but then charged for return shipoing of the fixed/replaced unit.

Id just write it, and the company off in such a scenario.
Im hoping no warranty work is ever required.

My makita charger, well wanted a PSW inverter to charge via van when required.
I.decided.to split the wire amd measure amperage bia clampmeter, amd saw an initial rate that made me get a 400 watt PSW inverter. I believe it was drawing 250 watts initially.

The ridgid charger has a separate cradle amd a '60 watt' wall wart '18v' power supply.

I suslect there are no brains in power supply, only cradle.
I.suspect.one could cut the 2 cradle wires, and supply it 21.01v via a dc to dc buck converter, and avoid the inverter.

If i decide to buy 2 new 4.0 ah batteriezs, with the charger, ill void waarranty on one charger and open it up and check voltage on the + and -, and see what terminals T1 and T2 are doing, while charging.

Thd ryobi failed battery had a plug driven into casing over one deeply recessed security torx bit screw which js imossible.to remove without mangling the plug, making it obvious it was tampered.with.

I didnt notice any such device on the Ridgid, to determine if the consumer tampered with it, but didnt examine super. CLosely, yet.

I have a 150 watt boost.converter.
The 400 watt PSW inverter i bought, primarily for.Makita charger, failed a few years ago, with very little use.

The ridgid 18v system is likely more vandweller friendly..

Generally the wall wart.power.supplies.dont have issues with MSW inverters, but the ridgid cradle might just need 21vdc delivered to it, and a 150 watt dc to dc bokst converter can be obtained for as little as 1.50$

I.am.inter3stex to see which 18650 cells ridgid used.
While the battery packs are rated in voltage and amp hours, the highest capa ity cells cant maintain their voltage at high loads. Kind of.like deep cy le vs startkng.

The actual cells used pretty much determine the power.of the tool.
There are some.powerful higher capacity cells.availabme now, bit they are not cheap.

Here are the cell specifics of the 4 good LG cells i pulled from the  Ryobi battery pack.

https://lygte-info.dk/review/batteries20...%20UK.html

Note his conclusion at the end.
This cell is rated at 22 amps max, and only has 1500mah capacity.
I know samsung has a 30 amp 18650 cell.with 3000mah capacity, and 21700 cells are.now being out into some.powertool battery packs.
Some.of these are rated at 4500mah amd 50 amps max.  One coukd possibly get/make a 4.5ah 18v battery out of just 5 cell,.or a.9ah battery out of 10.

The 2 4.0 ridgid 18v battery packs.for 79$ is likely using 10 2000 mah cells, but which cells?

The 4 good LG cells i pulledd from the ryobi pack test very similarly now, after lots of abuse then sitting on the shelf for years.
Its important to have relatively closely matched  grade A cells, which js why i dont trust the generic half price makita baTtery packs.

I was.going through  cheap 6 and 9  cell laptolp battery packs, and when theyd fail and id test the ok cells.individually, their capacity was all over the place, and way low, 450 to.600 mah.

I quit bothering with trying to repurpose them.

The 2 ridgid 18v for.80 $ deal has me suspicious. 
Perhaps they are about to offer a new line of  marginally larger 18v batteries with  50 amp rated 21700  cells.with 4500mah.
Perhaps these 80$ deal.batteries are known to have the occasional bad  cell And high return rate.

Anyway i want the jobsite blower, and more batteries, but dont really need them,.presently.

Stupid Ryobi leaf blower.
HIDEOUS baby puke green color
Weak output.
On/off only, no speed control.
Stupid paddle .on off.switch.

Horrible.non axial fan design with its ultra annoying pitch.
Cant even put.it.down as its.intake gets blocked.

Stupid worthless.POS.

Its mother is so fat and ugly.....

I should really just order the Ridgid blower, and 2 4.0 ah batteries right?

I.promise.ill take caRe.of it, walk it and feed it and give it flea baths,.only allow.it.to feed.on filtered lemon scented air....

Right?

Snost
lost. the 80$ deal, for 2 4.0Ah batteries, is now 277$

Said the offer was good for 5 more days, last night, and 6100 units left at that price.

nevermind.

Oh Ryobi, please forgive me.

You know what tool now deserves some mocking? my corded chicago electric 4.5 inch Angie grinder.

The stupid thing set me back about 18$ in 2005 and has been beat to snot, caked in cut off wheel dust and 'other'

Had to fix power cord once, and now brushes have to be near toast, and one.of 4 gearbox screws loosened and lost itself.

I.didnt use it at reduced speeds on a router speed controller, for hours.on end, foiling wood.surfboard fins, or.honing the sliprings on my chrysler alternator, or wirewheeling roof gutter rust.
The switch is not a bitloose and imprecise
It otherwise does not still work perfectly and spun a 40 grit flap sander just today.

Yesterday , the Ridgid 18v 4.5 angle grinder was 139$, tool only. Nope.

Today, it comes with 2, 4.0 ah batteries, and charger, for 179$.

Arrives by friday......

Woulda preferred the blower and batteries/charger for same price, but snost and lost.

This is the plastic 18650 holder that came inside the 18v Ryobi battery pack.
   

It's quite burly...
If I leave the 2 screws loosened, just enough, then can insert and remove cell    


 squeeze together to lock,.pry apart with 2 hands to tip out one cell.

The protected 18650.cell that I have are a bit taller, like 68mm tall, not 65 .which is not.so much an  issue, but the 18.25mm width that is.

Solder blobs on the + end of flattop cells are frowned upon.

The panasonic NCR 18650 B cell on the far right, is my oldest quality high capacity cell. 10 years old seems a reasonable age guestimate
 
First solder blob too. Added 8 years ago or so.
