Hitachi Impact Driver & Battery (Nicd to Li-ion) Restoration | HITACHI FWH 12DC2

Hitachi Impact Driver & Battery Restoration Video.
I found this impact driver from secondhand container from Japan. This tool is designed really good quality, made in China and selling in Japan. The inside mechanic is the same other impact driver, but the battery is different, I spent a lot of time on battery conversion. I upgraded the battery from Nicd 1200mAh to Lithium battery pack 3200mAh. I also cleaned the driver housing, add new grease into gearbox and restored the dead DC motor. After I have done the battery rebuild and refreshed the driver, I started the testing. This impact driver is more silent than the Bosh impact driver I restored last time. I feel comfortable while using this driver, I love it.
Battery upgraded items
- Battery 18650 Lithium or Li-ion 3.7V 3200mAh
- BMS 3S20A enhances the life span of the battery cells
- DC female power jack for charging the battery pack
- Nickel strip
Cleaning substance
- Backing Soda
- Hot water
- Laundry powder
- W-40 degreaser
I hope you find something useful & enjoy this video!
I am happy to receive your feedback, advice, suggestions to improve myself.
!!! I apologize for the mistake if I have made in this restoration !!!
**I still keep some parts, I want to save the world's environment**

Better than new because it's Old! Very well done. You could make millions just rebuilding Battery packs. Thanks for machine noise only.

I'd have painted that motor to prevent rusting again. Great job as always

[@taunteratwill1787]

Oh my god! This is so original and new! You never see this on KZbin! Please do another one for all who might have missed this enlightning work!

[@JimNicolaus]

Great videos, I like to put the new charger in the old charging station. Remove the charging station internals, replace with new charger and charge the lith batteries in the station as before.

Molto bravo, come é in uso dire due mani d'oro. Avessimo i politici con queste capacità avremmo risolto molti dei problemi del n.s. paese. Rinnovo i miei complimenti.

...most fascinating to me is the battery rebuild...that could become a side business in itself...there a literally thousands of cordless tools piled in our garages begging to be restored, mostly due to battery issues...

[@aserta]

It is a business. There's lots of people doing this at greater or lower cost, with good or bad results. Ultimately, unless it's a company, you'll never get a guarantee the job's done right, and even then it's a dangerous affair. Battery packs are not something you mess with and get away with if you don't do it correctly. So that's why it's not a hit and miss, on both sides of the spectrum, customer, and service provider.

[@ltdees2362]

@@aserta your so right, there are many aspects you must consider before attempting a battery restore/repair of this nature. For me, I just purchase a new battery and be done with it 👍

[@hunter7476]

@@ltdees2362 even if we dont its still cool that people like this guy that restore these tools back to their original condition fully restored and back to work its fun to build and fix

What I love about his videos is that he has repaired/restored so many nice brand tools and yet he stays attached to the same ghetto brand impact driver when doing work. :)

Amazing work man. Hope to try this out one day on tools. Currently helping clients by servicing their fishing reels follow most of your steps. Have you ever though of getting a ultrasonic cleaner for the part that require proper washes? I've heard that it does amazing work on cleaning. Thanks for video keep it up Cheers

I have this same impact driver.. U.S. branded. Still use it a lot as it fits the hand well and always worked good. I rebuilt the nicads a few times. Now I've just mated the handle insert of the battery to a 3-D printed DeWalt adaptor. Now it accepts Dewalt 12v Li-Ion. There are no adaptors made for these old Hitachi drills
