Great Job. You make it look so easy. I have 3 Norelco Razors so at some time I probably will be replacing the batteries. Thanks for all the information & it was a really quality video. People really don't realize how difficult it is to make a good video that is focused correctly & clear & easy to see all the details. Thanks again. Sincerely, JAMES.

Have a norelco 9800 series shaver but wanted to use my old shaver s738 shaver (which had a dead battery) Saw your video ,highly educational for rookies Now i just need to buy solder material and equipment Thanks again

Fighting against obsolescence! Great tutorial, thanks

thanks for having this video... dad wanted to change battery. Love that you had it step by step.. found out they gave him the wrong battery LOL

Excellent video. Thx for taking the time to record this process in full details with great close-up shots and sharing it.

I think it is very important for safety reasons that you don’t give the wrong information about batteries as they don’t all use the same charger and if an unsuspecting novice on your advice would put it the wrong battery you can make the things go booooom. Another thing I noticed was the way you put the screws back in there holes by straight away turning them clockwise and by doing so you can damage the thread in the soft plastic. ( called stripping the thread ) These screws are “ self tappers and if not put in their proper groove can render your hole useless . My advise “ insert screw in hole, insert screwdriver into screw , turn anti clockwise and put slight pressure on screwdriver until you hear a slight “ click “ which means the screw is in the groove of the tread and now go clockwise and tighten screw !

Excellent video, good quality and smart placement of shaver. Easy to follow. I think I will give it a try. Mine is a Phillips Philishave wet model (pre Aqua touch), at least 15+ years old, so doesn't owe me anything. The battery life is 2-3 shaves, and replaced the blades once so no complaints. Just in case, I bought a new model (on sale) ,but will keep the old shaver as a spare for travel.

Appreciated your detail. All looks same as my 8240XL except my battery is Lithium Ion 3.7Vdc 750 mAh . I liked the demo of the solder sucker. Wish I had one; but, I opted for the less expensive (will seldom use) solder wick. My battery tabs do not match length or width so will need to trim both. My less expensive (older model) Reflex Plus 6617X uses the 1.2Vdc Ni-MH battery, but, your instructions came in handy for both shavers. Note: I removed the battery w/o noting the polarity. Your mention of polarity answered the remaining question I had before finishing my battery install. Thank You

The solder sucking was satisfying to watch ... nice job, Tom 👍👍👍👍

Thanks, Tom. I have a System 7000 shaver that I am refurbishing. It is a little different in assembly detail, but your video worked for me. It was not too technically difficult at all. I appreciate your time in making the video. The Li cell is standard in my model, and I am pretty sure that your original (at 4.0 Vdc) was actually Li also, and the charger should be Li specific also (for safe operation); but, I can only be certain where my own unit is concerned. No matter though, the process was still good and applies. Thanks again! Steve M

Very well done. I accidentally dropped mine in 2012, and broke the part that flexes and holds the blades in place. My girlfriend replaced it with a cheaper one from Sam's Club, which only works when the charging cable is disconnected. I'm very happy with my current razor, but I definitely miss my XL. I recently tore it apart to repurpose, and make a personal fan for my daughter. The unit works as well as the day I bought it, but now it has a new reason for living. My XL is easily the best I've ever owned. Thank you for this video.

THANK YOU for actually telling us what Tool you used (T9). Watched numerous other videos whether they didn't even say what tool they were using. Good job!

Great video, excellent camera work and explanation of the process. Ready to change out my own battery now.

Excellent video! I have a 8170XL that just stopped working and have used your video to remove the battery, and have the new one on order.

Hi Tom, Many thanks. just replaced the battery according to your instructions. Works excellent. All the best Bro

Good man - nice and clear. You'd think they didn't want us to replace the batteries ; -)

Good video, very helpful. It was easy to take apart. Unfortunately the tabs on the new suggested battery were ore than twice as thick than the original and a bear to trim down. Also, on my 3000, I had to unsolder the two small wires so I had access to the battery tabs. Unfortunately, the solder sucker did not want to draw out all the solder from the tiny holes. I had to poke the wires into the holes while holding them in small pliers in one hand, solder gun in the other. A minute and a half to take it apart, hour and a half messing with the battery and wires, a minute to put it back together. Just a tiny bit tedious! Haha! It’s good to have a hobby. I’m not a fan of all the planned obsolescence these days.

Thank you for your efforts and this very informative video. It helped us out big time. 👌👍😎

Nice presentation, thanks! As with automotive repair, it looks like more than half the battle is having the tools on hand to do the job!

Thank you for your help - it may be beyond me but I'm grateful for the clarity of your explanation

Thank you for the video! It was very helpful!

Excellent Video! Thanks for making a positive detailed explanation of a process!

Nice clean de-soldering job.

I've had an 8150XL for nearly 17 years, regularly shaving 5 or 6 times a week for the last 10 years, and the battery is just now starting to lose charge noticeably faster. Based on the budget you describe I'm leaning towards full replacement when it drops off too much. I've already replaced the blades once along the way

Nice job done! Congratulations! Only the battery link shows a double batteries in parallel each is 2.4v quite different from the video you showed here.

I also have this model of Norelco shaver. Worked fine for almost ten years, and then one day it just quit. It would only run if the charging cord was plugged in. I suspected that the battery had went kaput, so I disassembled it to see if the battery could be replaced. Like you, I found that it was a simple operation to replace the battery. Ironically, the date code printed on the PCB was 06-05-17, which was oddly close to the actual date the shaver quit working. First, I thought that the microcontroller was programmed to kill the shaver on or around that date, forcing you to purchase another one. But since replacing the battery fixed it, that might not be the case. Unless removing the power reset the controller?

Very nicely made video, - thank you!

Very nice job , easy to understand thank you

Very nice video. I am ready to replace mine and this will help tremendously. So how does the new batter holds up after almost 7 years since the video release? Thanks sir.

Thank you so much for your help.

Nice job!I can make modification for my Philips HQ-8100?This shaver have only powered by 220 v.,but inside have also place for a battery.

Great, thank you so much it was very helpful

Where did you get the battery for this razor as the one in my 7340xl Norelco doesn't have any information on it to make sure it is the right kind.

I like the video. Good attention to the [de-] soldering part. What make & power iron were you using?

Great demonstration

ThanksTom for the excellent explanation and video guide. I have a Philips SmartTouch XL which looks very similar to the Norelco in your video. The battery is also green like yours but the only markings on it are STG 2KLO6E?! You say yours is a Ni-Cad. Where would I get a replacement battery? This shaver is really neat and I'd love to keep it going! 🙂

dont they sell these shavers without the rechargeable batteries but with a cord only? How often do you have to replace the blades?

It appears that your new battery was a rechargeable Lithium Ion battery (new battery in video was CR14500) NiCd battery voltages are 1.2Vdc not 3.7Vdc, Also it is not an "ordinary" AA battery as you stated in the video.. You should more accurately describe the parts used in your videos. Yes some Norelco shavers use a NiCd battery, usually a pair. Others seem to use the Li-ion rechargeable.

I have the same shaver, where did you get the P/N battery:. Model 8151XL Shaver. Ni-cad battery: 3.7 volts, 750 mah, metal tabs..

Love that solder sucker going to order one online now

Where can I get a battery for my philips shaver? Mine is a different model than yours but maybe the same battery.

Nice video! thanks

I have Aquatouch 5000 series, i cant find its original cell, in market available cheap one like $2 for one piece, I replaced but its now giving proper power, after full charge it drops within seconds. Is it issue of cell or circuit board?

Excellent. Thank you.

Man thx só much, very usefull, save my device.

The battery you used is a lithium battery, not a Nickel Cadmium. You did replace the battery with the correct battery however you are explaining the battery incorrectly. The battery you used is a ICR14500 which means: ICR - Lithium Cobalt Oxide 14500 - Standard AA size (14mm diameter and 50mm length of cell) Hope this helps anyone else.

Hi Tom! Thank you for the video! Tell me, was the new battery li-ion or ni-cd?

thanks for the great info

Thank you so much for sharing this Video. It was such a Big help. :D

What size of the torx screwdriver?

What wattage is your soldering iron? I may have a solder sucker but finding it... Well it may better to just buy another shaver.

excellent thank you

Hola necesito si es posible donde va soldada la toma de la bateria (-) tengo la misma maquina o parecida

A new model 4500 Norelco Aquatec is $81 today on Amazon. New battery is $15 including free shipping. If this takes me an hour, I've earned $65 per hour, tax free, and had fun doing it. I'd have to earn $80 before tax to clear that. Sounds worth it to me! :)

good job sir i really like the way you repaires this rasoir thanks for this amazing vidéo

illuminating

question i have is why are the chargers 15 volt when batteries are no more than 4 volt

Thanks!

Can you explain, How to Replace Philips Norelco 6866XL Shaver NiCad battery

Hi, I enjoyed the video. Question. I have a Speed - XL shaver. Which battery must I buy? Thanks

Hi Tom,Great video. Can you tell me where you purchased the stand with the alligator clips and magnifying glass? Or at least, what these stands are called? Thanks!

I am thinking about upgrading to 2500 mah NiMh low self discharged battery and three new generic brand razor heads cost $1.69 each($5.07 total one set) on my dad's 7110 then same on my 7310 (originally both use 1.2V NiMh batteries) but not sure about which side is positive and which is negative, any suggestions on that? Will a regular AA rechargeable battery work? I can tell the positive side easily.

Tom-excellent video!! Thank you. Where can you buy a solder iron like you used? Is it an automotive repair store or hardware store purchase? Thanks very much!

Hi Tom, great video. Is there any danger (to the razor's charging system or whatever) to replace the battery with one having a higher mAh rating? Thinking of a 2000mAh battery to replace a 1650mAh. thx

Я думал только в России чинят технику. Молодец!

Hi! So I tried this exact replacement and everything looked good, but before I soldered the battery in I accidentally dropped it and with out thinking put it back in upside down. A puff of smoke came off the circit board and its isn't working anymore. does anyone have any idea what part of the circuit board I most likely fried, and if so is it easy to replace?

Yo busco la cabeza de esta afeitadora

Yeah, but the 50 dollar one does not compare to the way more expensive XL Speed model, it actually has 3 concentric rows of cutters in each head for a total of 9 whereas the 50 dollar one just has one row per head for a total of 3. Great job, let me know your opinion of how they compare if you can. Thanks for great video.

The battery died in mine but when I realized the shaver will run directly off of the wall outlet, I decided to avoid buying either a battery or a new shaver. Win-win for me and the environment.

So the battery has to be installed with the positive up toward the motor..and negative at the bottom?

If it fits, can I replace that NiCd battery with a Lithium Ion 18650 battery? Thanks.

Cool!!!

Does anyone know the voltage of the internal battery for a 8240XL Norelco??

Can you make the shaver run on AC only No battery?

Please correct the battery information. This is a 3.7V Lithium Ion battery (shown at 10:12), not a 1.2V NiCd.

After watching this I put my Norelco shaver into the trash can!

I changed my battery the same as yours and the cost on eBay was £4.00 from China

Where do you get the batter

link in description points to a battery that doesn't fit this shaver. I just purchased this battery for an 8140XL shaver: smile.amazon.com/gp/product/B07H5T6VCT/

Is it still working? Maybe there was a problem with charging?

Lithium ion battery. Nicad is 1.2 volts. It is not exactly a aa size either.

Sorry, 3.7 volts is either a LIPO or a Lithium Ion. AA batteries are 1.5 volt and 1.2 for cadium rechargeables.

One additional complication the DIY razor repair person may encounter - - I discovered today that the Dutchman who assembled my Norelco 7310XL decided to further secure the battery with double-sided tape. GRRRR... Ronsonol lighter fluid to the rescue.

By some (or may be most) shavers one should not try to "unsold" the accu contacts, 'cause the printed-circuit board would "go phut" irreparably! You should just carefully cut ("break") contacts from the accu body!

The soldering job was very sloppy, and I think he got lucky. After he removed the original battery, he should have used the Ohmmeter function of that Fluke meter to check for continuity between the battery soldering pads and the adjacent pads. The spacing between the adjacent soldering pads on this board is very tight, and the original soldering is done in a way that tightly controls the amount of solder that gets picked up by the pad. This guy bent the pads over nearly on top of a couple of adjacent pads and then applied solder to the opposite side of the hole. That isn't the ideal way to do this, and after he did that, he didn't check to make certain that he hadn't created any wrong solder bridges. Sloppy and lucky.

...stopped at "single double-a battery". It's just too much...

Greedy corporate companies are making it harder to change the batteries these days, because they want us to buy new products instead of repairing and upgrading the batteries. Same with Tech companies if the LCD broken buy new phone. I am thankful to EU that they continuous to impose new laws regarding chargers etc. i hope they make laws for -easy to change/upgrade parts. -a common charger, currently Apple's fast charger doesn't fast charge other products and vice versa -a common power plug across the whole world currently every country have their own plug type. -easy to change/upgrade parts. -mobile with atleast 20,000 mah batteries :)... I will write this to EU, i hope they will listen to us.

I'm pretty sure those models use Ni-MH battery and not Ni-Cad

Just one comment. That is not a NiCad cell. It's a Lithium Ion cell.

My Norelco 3D doesn't even have visible screws to disassemble it. When the battery quits charging you have to throw the whole thing away. That's $100 wasted.

So heads ~$20 and battery ~$10 and entire package (including the razor itself) ~$30 ? So Norelco essentially gives out the razor for free when you buy as a package? But why toss out a perfectly good razor with a good motor? Good economic sense, bad environmental sense. Would be nice if it was solder-less, usually batteries just snap in and out.

🤒😓

I’ve seen paint dry faster than this video.

It's not an AA battery.

Are you morpheus asmr?

Try a nitecore 14500 next time . Its 6.5 amp!! 650ah
