I've just done this with a cheap Rowenta shaver I've had for about 2 years now..While fixing it I noticed the battery was fine but On/off button stopped working and I don't really have the knowledge or time to replace a tiny button...plus the battery was really crap. Now all I need to do is plug it and enjoy unlimited power. Works like a dream. Good stuff!!!

The battery is $12 on Amazon. This repair, however, is FREE. I was actually thinking about running mine off a USB power bank with a diode on each power wire to drop the 5v to 3.4v, but your solution is much easier - either way, I'm tethered to a power source.

If you desolder the battery from the PCB and simply run a wire from the charge port's + (red wire) up to the B+ (battery pos.) terminal, you can retain use of the power switch! (You will need to find a way to secure the PCB to the case, I rolled up some thin cardboard and shoved it where the battery used to be.) The ground is wired straight through. I just did this myself, it took me longer to find my soldering iron than it did to mod the wiring.

Yeah, I have always questioned the "convenience" of many cordless products as the hassle with keeping the batteries charged can often exceed any issues using a cord may present. I have a former cordless drill that the batteries died on many years ago and I just added a lead to it that goes to a couple of large alligator clips. So I use it with a small 12 volt SLA battery and it goes for ages before I need to recharge or if I am using it for a long duration in one place I can just use it with a car battery. So in effect it's "semi-cordless", but without the sudden death effect of onboard Li-ion or NiMH batteries. The other thing I have is a lawn mower, one of the first rechargeable electric models. These were particularly terrible as the motor essentially overloaded the two 17AH SLA batteries that were series connected as the power source. Thus the batteries have a short & hard life as they were being overrun by design. I got this for $20NZD from an auction site & naturally the batteries were long since stuffed. So I removed the batteries and connected a 25 meter lead made from 3mm^2 speaker cable fitted with a 50 amp Anderson connector. This then mates with a similar connector that takes power from our 24 volt house bank. Thus I now have a standard corded electric mower except that it runs from 24 volts DC, which is great when you are off the grid. I have always used electric mowers so have never had an issue with using a cord. Now with the mod, this one is the best I have ever used! :)

Good on you. Those are great stories on hacking a solution. I once converted a 24 volt batter weed wacker to 36 volt AC source from a small transformer. Being the brushed motors are universal motor you can run them on AC or DC provided the volts are not too far off and the only thing running on the power is the motor.

I found this video because I have a couple of these trimmers but they have the 1.2V NiCad cells. They always have seemed a little anemic so I was considering either a lithium conversion or a DC booster to 3 or 5V. I may try this with one and see how it works out. A couple of things to note about the switch: 1) They are junk. I've noticed the speed dropping off seemingly dead but then I bump the trimmer and then it will speed up again. 2) Notice the 3 pads for the switch. It's a SPDT with the battery + as the common. It connects to either the charge port or the motor. This is why you can't charge and shave at the same time.

Part of the problem with devices like this with rechargeable cells is that they are built down to the lowest cost possible, and don't use proper battery charging circuits. This has become somewhat less of a problem since lots of devices have gone to lithium cells that require proper chargers to not burst into flames. But I have several old Black and Decker cordless screwdrivers that NiCd or NiMH batteries. The charger circuit is nothing but a transformer, a charge indicator LED, and one resistor. That's it. Three components. They are using the charge indicator LED as the rectifier diode to charge the battery with half wave rectified AC and the resistor to limit the current. No actual charge control. If you leave the battery in the charger indefinitely when not in use, the charger kills the battery. I've bought new batteries and remembered to only put them in the charger for 8 to 10 hours and then remove them, and they lasted fine for a year or two, then I forget them in the charger for a few days and after that their capacity is greatly reduced and they don't hold a charge for more than a few days because of the damage by overcharging. Also, I have a cheap battery powered toothbrush with an inductive charging base. I took the brush apart once just out of curiosity and the charging circuit in the brush is just a coil, diode, and battery. If you leave it in the base all the time it is always warm. I realized right when I got it, long before taking it apart, that it wasn't doing proper charge control. The warmth is due to the battery being overcharged. So I only plug the charger base in when the brush actually starts noticeably slowing down, and then I only leave the charger plugged in over one night. The thing is, I can use it twice a day for probably two weeks before it needs to be charged again. So that means when most people just leave the charger base plugged in, it's cooking the battery most of the time. It only really needs about 8 hours on charge once every two weeks. As much as I usually hate the government meddling with things, I've seen so many of these dumb charger circuits that I think they should make a law that requires proper charger circuits that don't kill batteries.

I had this same low charging battery problem with the same model trimmer and I removed the battery and moved/re-soldered the wires from the motor to the corresponding +/- battery terminals and mine now runs off of the cord with the switch working. The blue (-) wire is not long enough so you have to pigtail a new piece of wire onto it so it reaches the far end of the board. This is a great hack and so what if it's not cordless for home bathroom use.

Good to know I'm not the only one with this problem. It looks like the circuit has a couple dual transistor in IC packages that which out the power lines to the charge control IC when jacked into an outlet. It most likely does this as the load would be too much to run the motor and charge at the same time. However a bit of clever switch work on the PCB could have forced a direct power switch to the motor when in the on position and back to the battery charging circuit when in the off position. I guess they just didn't want the extra work and testing to make sure the motor would always kick over and start as 600mA is a bit low and the way the SMP supply works it could very easily not be able to kick on regulation without the correct load.

True, but then I would still be faced with cracking this thing open every year or two to replace the solder tab rechargeable and I really can't recall being in a place where I needed to trim up but didn't have power so I was OK giving up on the battery option. Guess I could always order another male barrel jack and wire up a 3 pack external battery pack if I ever had such a need. It would still be on a cord just the cord would go to a battery pack or one of those 5 volt travel charging packs maybe. Best of both worlds without the need to replace rechargeables.

Would there be any way to hack a shaver though so that the charging circuit does work but only when it's not turned on by the switch on the shaver body? I have a Philips SW5700 and if it runs out then you can't use it until it's charged again. Would be nice to still be able to charge it though as when going somewhere you may not always find a shaver socket or plug (out in the wilds) so being able to still have it as rechargeable but also work from mains would be great. My old shaver (unfortunately broke down some time back now) used to allow you to plug it into the mains and use it and then when you weren't using it (in other words the shaver on/off button was in the off position) then it would charge up. Would be great to be able to do that as then you have the absolute best of both worlds.

In the trimmer there is not one, but two identical AA size Ni-MH rechargeable batteries connected together in series (the + end of the first unit to the - end of the second), each unit is of 1.2V and 600mAh, which means the overall voltage of the system should sum up to 2.4V, and the overall storage capacity remains the same, 600mAh. I have no idea why this method shown in the video didn't worked for me, because in theory it should.

Most likely there is a boost converter in the circuit that pushes the volts up anyway. If you have a variable bench power supply then hook it up to the motor and ramp up the voltage and watch the current loading. If the motoer stays within normal operational limits as compared when powered through the 2.4v battery hookup point then you're fine. If you don't have a power supply then just hook it up for few seconds and if it sounds like it's running at the same or close to same speed then it's fine. In my case I didn't care if the motor didn't work on its direct wall wart power because it was trash if it didn't work anyway.

Hello there, i have charger with 3,6V and battery that is inside is 1,2V does this 3x difference could destroy my motor inside?

If you bypass all circuits and connect your charger to the motor you will be fine. If the changer cnd put out enough amps it will even work, just like in my video. Sometimes I have to give it a wack and/or clean/oil the blades good before it works will on the charger.

@@ToddFun problem is that batery was 730 mah and the charger is 100mah ... i tryed with 400mah charger but that was not enough... now i will try to find stronger one with atleast 700 mah... or do you recommend something else to do? Thank you for reply.

@@dejanmarkovic1974 mah is just capacity. Like saying you have a gallon of water or a cup of water. Chargers are not rated in mah they are rated for a given regulated voltage and max current in amps. You just need a charger with something close to what the motor runs at voltage wise and also has a DC amp rating high enough to power the motor. 600 ma to 1 amp should be fine. Any good old usb phone charger will do just fine. They put out 5v regulated DC and 1 to 2 amps. you can even use a usb cord, just chop of the end to wire up to your shaver motor and you'll be good.

Thanks for this as my Wahl trend trimmer Ni-Cad battery is just about dead. I have taken the trimmer apart and there is a single 1.2 volt battery and my charger is AC/DC 1.2v -2000mA. My query is that at the 1.2v DC motor I have three compnents which are indicated 47. Not sure if they are capacitors or resistors, two connect each motor input to its' casing and the third joins both inputs. So when checking continuity from the charger lead I get readings from both leads to both motor inputs. Can you please advise if it is safe to proceed or should I remove the linking component? Thanks Graham

Not sure at all what you are asking. However I can say that a motor will only read as a few ohms and so will pass a continuity test at both its positive and negative leads when in a circuit.

would the same principle work on 20v cordless tools?
@ToddFun
7 жыл бұрын
Not likely as the amps needed to keep the 20v tools running correctly would be higher than what the charger pack's power regulation could deliver continues. You would need a new power source that puts out 20v DC at very high amps. Some cordless tools do still use universal motors so you could use AC instead of DC from a large 24v AC transformer like found in sprinkler controls and old school door bells. You could use that straight into the tool. So if the tool uses brushes it should work straight off a large 24v AC transformer and should get enough amps to run too. If the transformer starts to get hot then you know you need a bigger 24v transformer. If the tool is brushless or not a universal motor then you will have to create a power supply that included 20v DC regulation but can still deliver a lot of amps which would be costly, best to get get new batteries and a new charger if needed. One last note, if the tool is of the top shelf variety with the fancy speed control triggers the 24v AC might make the control circuits malfunction and might even damage such circuits if they don't have reverse blocking diodes so do such tests at your own tool's risk and don't hold me responsible for such failures as I'm not there and I don't know what is inside ever power tool. Good luck hacking.

Would anyone recommend me doing this to my trimmer? I just bought it yesterday and when I got home I realised that it charges for 10 hours and only runs for 45 mins..
@ToddFun
6 жыл бұрын
No, 45 mins is just fine for such a device. The batteries don't have that much capacity in these small trimmers and they do charge slow. However, if you don't care for the cordless you could do this hack. I know I still use mine and it love that it never stops because I'm always at my sink and there is always an outlet to plug into at my sink anyway.

would the same principle work on 20v cordless tools? how do I know how many Amper does the drill needs? I was thinking about laptop charge but I was stuck with the ampes.
@ToddFun

The amp reading will be on the laptop power brick. Their range can be high but maybe not enough for power tools for full torque. As long as the power brick puts out 18-20v DC you can try regardless of the amps. If the amps are too low the tool will not run or will just torque out and stop. If the amps are too much the tool will run just fine as it will only pull as many amps as it needs from the 20v DC regulated supply.

Todd Harrison, what will be the life of my trimmer if I use your method with a 5watt source once a week? For these type of dc motor, i read that they can run upto 7000rpm. So using a higher watt source will definitely increase the rpm. Are there any chances that the motor will burn because of this? Thank you in advance
@ToddFun

Sounds like the source is going to be limited to 200 mA so it might even brown out on you under load or if it gets dirty. The 5v is going to be just fine. It can't hurt itself on 5v. The issue is will it get enough current to even drive it well, 1000 mah isn't much at all for a motor at 5v.
