Question by John S: How can I replace a power tool battery with an ac adapter?
I have several old power tool batteries that have died over the years… I really don’t like buying them over and over.
I got the bright idea (oh no), if I could find an ac adapter with the same volt and amp output, and I could fit it inside a battery case (take the batteries out of the housing), then I wouldn’t need more than one or two batteries while I’m away from an outlet. (Most of what I do, I do close to an outlet. Having cordless tools are just very nice.)
Anyway, I found an adapter with the spec I needed on eBay. Got it home and checked it out on my (right on the money for volts; less than 1/2 amp higher than the batteries).
I emptied out a worthless battery, fit the adapter in, carved a hole for the cord and fit the wires inside to connect to the “battery” terminals. Now it looks just like a regular battery, test the same, it just has a cord hanging out.
When I put it in any of my tools, however, the tool runs in VERY short bursts.
What did I do wrong?
New information…. (I’m still trying to figure it out)

If I the “battery” into a tool that is variable speed and sloooowly squeeze the trigger, THE TOOL RUNS GREAT!
If I squeeze too fast, though, it sounds just like a non variable speed tool.
rumm… rumm… rumm… about once per second.
Well… I thought it ran great. It only SOUNDED like it was running great. When you put it under a load, it dies. At full clutch, I can stop the drill with minimal effort with one hand. With a good battery and at full clutch, this drill is a wrist-breaker if it jams a bit in something!
What’s going on?!
If you read a bit closer, you’ll see I’m talking about a thing I made. Not a gimmick… I created it. It’s not a battery, but an ac adapter that I put in a battery housing.
It is an ac to dc adapter.
And it was not an easy fit into the battery housing; it’s sitting at a sharp angle and a little carving on the battery housing was needed to get the top screwed down. (ryobi 18v)

As every test I’ve learned to do says it doesn’t have enough amps, my next plan is to replace the adapter with a laptop adapter at 18.5V and 6.5 amps.
That will either be enough, burn the motor up or tell me it isn’t going to work no matter what.

I really hope someone has a better idea.

I have never seen the unit you are talking about, but it sounds like it is a battery with a built in charger. Leave this plugged in for an hour, if it runs longer ( like a battery ) this may be true. Sounds like a Gimmick to get you to buy. Sorry. The of cordless drills is to use where power is not available. I have 2 cordless drills and 1 corded drill. Each is designed for a specific use. If you are using near a power source often, I would recommend a corded drill, they are more powerful anyway, and come pretty cheap these days

    This review is from: DEWALT Bare-Tool DCS370B 18-Volt Cordless Band Saw (Tool Only, No Battery) (Tools & Home Improvement)

    This portable bandsaw is great for tradesmen who frequently cut metal, like myself, a commercial plumber. This tool is awesome because I don’t have to use a tubing cutter and wreck my wrists. Being cordless is great for working off a lift too.
    This would be even better for an electrician.

    I have used the Milwuakee bandsaw as well and it is probably superior. It can cut up to 3 1/4″ whereas the DeWalt only goes to 2 1/2″. Actually not a huge deal but advantage goes to Milwuakee. DeWalt batteries are cheaper though. DeWalt saw also has a hook that I love. The grip is differant too, I think I prefer the Milwaukee style grip, the Dewalt is “overhead” so to speak and Milwuakee’s is at an angle. Not a huge deal, and you get used too either. The DeWalt saw also has no breaks so after you release the trigger it’ll go for another second, annoying. Milwuakee’s has breaks. Milwuakee also has a quick release on the blade guard that is supposed to be an advantage(so you can make flush cuts against a wall) but I find this feature annoying. Everytime you set down the Milwuakee down the little guard goes in the up position, not ideal. The trigger saftey on both saws are annoying, but I prefer the Dewalt’s style, but I will likely mod it eventually so I don’t have to bother with it. The Milwaukee feels heavier to me but I have never weighed them.

    So why did I choose DeWalt? I have many Dewalt cordless tools, batteries, chargers, and the radio and this is the main reason. Even though Milwaukee’s is slightly superior to me, having one set of batteries and chargers in more important. I also think the DeWalt drills and sawzalls(cordless) are better so I won’t be switching to Milwuakee anytime soon.

    Portable bandsaw, August 16, 2012

    Every time I cut pipes and strut with a portaband I smile because I remember how long I did it with a recip saw and how much harder it is that way. This bandsaw in comparison to my Milwaukee Deep Cut Corded cuts at the same speed as 3 (out of 4 speeds) on the Milwaukee. However, a regular bandsaw is a much larger tool to drag out for just three or so cuts on small material like strut. It takes up a lot of room on your job cart. That’s where this little guy comes in. Dewalt made one small enough to fit in a 5 gallon bucket. Great for aerial work from lifts. Threaded rod too long and you’ve already put it in the beam clamp, no problem just nip it off with this. It will cut up to 2″ Sch 80 pipe (2 1/2″). I haven’t tested the battery to death but it easily made 10 cuts on uni-strut and still had plenty to go. This is a Stout bandsaw in disguise, but uses your Dewalt batteries. It’s weight distribution allows for one handed cuts freeing your other hand to hold material. If you have this and a Tri-Vise its a lot more portable than a full size portaband and tristand. It has a nice built in hang hook.
    The blades are easy to find here on Amazon and Grainger. Some other reviewer had smoked up some info about discontinued tool and can’t get blades (i don’t know where he got that info from, but it’s false) If they were to discontinue a tool why would they start selling it as a lithium ion kit recently. The DW3986C blades are easy to find. 32 7/8″ x .020. The blades require a little more finesse and patience in getting them in and out of the saw compared to my Milwaukee. Mine did not come with a bag or box from Dewalt – I bought the Bare tool.
    I think it’s a great tool for commercial plumbing and electrical service work and it can be a useful asset to commercial construction projects as well.

    9/23/12 UPDATE: Still love this tool, but I snapped my first blade on it. I noticed that the tracking was off and likely caused the snap. This could have been from a drop or rough handling by an apprentice, so I’m not going to blame it on the tool. Be sure to read the manual and learn how to see if your blade is on track and how to adjust it; it’s pretty easy.

    suprised the thing runs at all.

    consider most battery’s, lets saya 12 volt at 2.5 amp hour, it puts out 12 volts at 2.5 amps for an hour before it dies. most adapters that could physically fit into a battery housing are small and deliver at most 12 volts at .5 amp hours – not enough for serious usage and chances are you’re going to burn out the adapter anytime soon.

    btw, you are using a AC to DC adapter? and not an AC to AC adapter

    By using the transformer to power the tool you have changed the amperage of the power supply , in a nut shell – this won’t work effectively . I’d suggest buying one that has available option for ac power . Very inventive idea though .

    I think its fabulous that someone else has an idea like me. Back in 1995 I had thought of this very idea. It was not until two years ago I invested over $ 10,000 and applied for a patent on this product. Back in June after 1-1/2 long years I received patent pending status. But anyway. What your problem is, is this. You have overlooked how much milliamps you need to efficiently drive your cordless tool. You are on the right path. Most cordless tools need at least a minimum of 1200 milliamps. I guarantee your transformer is only putting out around 400 milliamps. (I had this same problem in my first proto. You can find this on the label of one of the batteries.) Then you have to find a AC to DC transformer that will put out the milliamps you need. Remember Volts are like horse power and milliamps are like Torque. This my friend will correct your problem. Please do me a favor and don’t manufacture and sell this.
