I have a bunch of cordless tools purchased over the years from top of line
Panasonic drills to junk Black & Deckers. Except for B&D they all worked
pretty good when new but now all need batteries or will be needing it soon -
different voltages, different companies and none are interchangeable. Part
of my garage look like a repository for dead cordless tools. The cost for a
new set of batteries are hard to justify even for the excellent Panasonic
drills when a new and better model could be had for just a little more money
than a set of batteries and charger. Do you keep on buying overpriced
batteries, do you buy into an endless cycle of cordless (I'm such sucker for
tools) or go back to corded tools (so reliable, almost indestructible, last
forever and cheap when amortized over the years)?
I have six sets od Ryobi batteries and all depleted within 2 to 3 years. If
you work the Ryobi hard (and hot) like installing a fence or a deck with
long screws the battery won't last over 6 months - properly the same with
Panasonic but more so with Ryobi. Ryobi is good for the money but I wouldn't
equate them as fine quality tools like Panasonic, Hilti or Milwaukee.
Thanks for the heads up on the RC car racers. Are those old style chargers
you were referring to? Mine won't let me charge when the battery is hot, and
turn itself off when its fully charged so I could leave it in overnight or
even over the weekend. It comes to the point to decide if I want to get some
work done or baby the batteries - getting work done always come first. At
one time I had 4 sets of the Ryobi batteries and two chargers running
continuously and I was running out of batteries but my Panasonic with two
sets of batteries and a factory 15 minute charger could work all day long
without any interruptions. I know with a 15 minute fast charge the batteries
won't last long (still lasted longer than the Roybi) but getting the work
out is what its all about. The raw Panasonic batteries are pretty cheap at
ebay and I'll get a few and rebuild my power packs when I have some time.
Excellent point. My experience was my 14.4V cheap Ryobi had more torque than
my 12V Panasonic - what was a surprise. Now a Panasonic is every bit and
then some, in my opinion, as good as a Dewalt. Below is the torque found on
the web 12V vs. 14.4V. Couldn't find the torque for the 18V Ryobi but if
anything like the smaller 14.4V Ryobi it would kill the 12V Dewalt.
12V Dewalt 300 in-lb
14.4V Ryobi 350 in-lb
Rechargable batteries can last a long time if you Don`t follow the
manufacturers instructions, Mainly don't over charge, a warm pack is
fully charged, the heat you feel is chemical energy being transformed
into mechanical energy, heat, eating the cells, or only use a peak
charger, don't leave pack charging on a charger. Don`t over discharge,
when a tool just slows it is dead, stop or damage occurs even cell
polarity reversal. Cycle a pack never recharge immediately, or hot after
use, wait a day. Tool manufacturers make their big money selling you new
batteries. I have Makita packs from 1986 that still get some use. I
never ruined a pack yet and have maybe 15. The people that know cells
and how not to abuse them are RC car racers, Usually good articles in RC
car magazines. If you can open the pack get new Sanyos or Panasonics,
the industries best cell manufacturers and solder them in using heat
sinks and quick soldering, heat kills them
It would be electrical energy being transformed into chemical
energy,creating thermal energy(heat) in the process.
I would avoid any cordless tool that does not have a fast charger;one hour
or less.(smart chargers)
I hate cordless tools. They cost a lot of money over the years and
whats the point? A corded tool is cheaper, has more power, and dont
die at the wrong moment, requiring you to stop the job till a battery
charges. I bought a small generator for times when I cant get AC
power. If you ask me, they are nothing but another way to make money.
If you notice, they change the voltage every year or so, so you are
stuck having to buy a new tool. unless you want to spend a fortune on
95% of the time an extension cord does the trick and is the source of
nearly unlimited power.
I also have a small inverter and 12 V battery I can use when I need a
Cordless are a waste.
But the other 5% is sure is nice to have a cordless tool. Many people work
on ladders, towers, great distances from electricity that just love cordless
tools. Where I work, there is a 200' stack and the guys were doing
maintenance up there with cordless tools. As for the other 95%, I still
like the handy part of cordless. Don't like them, don't buy them. Your
choice; that's what makes America great and keeps the Chinese tool makers in
Actually, I did sort of solve that problem. I never could understand
why someone building a deck on their house would use a cordless tool
to drive the decking screws, when there is an outlet right in the
house within a short distance. However, there have been a couple of
instances where a cordless would be helpful. Last year Walmart had a
6volt cordless drill for $9. It does not have a replaceable battery
pack. The batteries are built right into the drill. It's obviously a
disposible drill. It has a nice keyed chuck on it (and I hate keyless
chucks). I was just looking into buying a replacement chuck for one
of my corded drills, and the chuck was $13. I bought this $9 drill
just for the chuck. However, I ended up charging it, and found it
does a nice job for a very cheap drill. I'll use it till the
batteries die, then remove the chuck and toss it. It worked nicely
when I had to change my rural mailbox, and didn't want to bother
hauling the generator and too far from the house for AC power.
Normally I would have just used a common screwdriver for this job but
it was freezing cold outside when the snowplow knocked my mailbox off
the post. This cheapie drill made the job fast enough that I didnt
get my fingers and toes frozen in the process.
Most people would consider this drill a toy. IT IS.....
But I consider ALL cordless tools toys....
I normally would not have bought something like this, except for the
chuck. I would not have. But even if it only lasts a year, it's worth
the $9. Big difference between this and spending $200 for a "brand
name" and then another $50 for each additional battery.
I had an old (30 years ago) cheap B&D drill that had the best chuck I ever
used. For hte most part, the keyless are pretty crappy, but so are the
cheap keyed chucks. I recently bought a Panasonic with keyless that
operates with one hand. It has not let me down yet. A few good ones do
Right, but then why did you buy Ryobi? I won't touch one of their tools
again. IMO, they are crap but I' glad you are happy with yours. Batteries
are junk after a year, switch needed to be replaced. Not worth it.
I really like my Panasonic drill, but I've had it less than a years so I
can't say how well the batteries will hold up. The power to weight ratio is
very good though. Easier to handle than my older lesser powered tool.
